说明书多功能双向髙密度电缆及其应用技术领域 Description Multifunctional bidirectional tantalum density cable and its application

本发明涉及地球物理勘探设备领域，尤其涉及多功能双向高密度电缆及其应用。 The present invention relates to the field of geophysical exploration equipment, and more particularly to multifunctional bidirectional high density cables and their applications.

背景技术 Background technique

地球物理勘探简称"物探"，即用物理的原理研究地质构造和解决找矿勘探中问题的方法。它是以各种岩石和矿石的密度、磁性、电性、弹性、放射性等物理性质的差异为研究基础，用不同的物理方法和物探仪器，探测天然的或人工的地球物理场的变化，通过分析、研究所获得的物探资料，推断、解释地质构造和矿产分布情况。目前主要的物探方法有：重力勘探、磁法勘探、电法勘探、地震勘探、放射性勘探等，其中电法勘探和地震勘探，是成本较低、施工最简单、探测效果也很明显的两种方法，目前在物探领域得到大规模的使用。 Geophysical exploration is referred to as "physical exploration", which is a method of studying geological structures using physical principles and solving problems in prospecting exploration. It is based on the differences in physical properties such as density, magnetic properties, electrical properties, elasticity, and radioactivity of various rocks and ores. Different physical methods and geophysical instruments are used to detect changes in natural or artificial geophysical fields. Analyze, obtain geophysical data from the institute, infer and explain the geological structure and mineral distribution. At present, the main geophysical methods are: gravity exploration, magnetic exploration, electrical exploration, seismic exploration, radioactive exploration, etc. Among them, electric exploration and seismic exploration are two types of low cost, simplest construction, and obvious detection effect. The method is currently used on a large scale in the field of geophysical exploration.

电法勘探是根据岩石和矿石电学性质（如导电性、电化学活动性、电磁感应特性和介电性，即所谓 "电性差异"）来找矿和研究地质构造的一种地球物理勘探方法。电法勘探分为两大类：直流电法（包括电阻率法、充电法、自然电场法和直流激发极化法等）和交流电法（包括交流激发极化法、电磁法、大地电磁场法、无线电波透视法和微波法等）。高密度电法是在常规电法基础上发展起来的，与常规电法相比，它具有成本低、效率高、信息丰富、解释方便、勘探能力强等优点。高密度电法指的是直流高密度电阻率法，但由于从中发展出直流激发极化法，所以统称高密度电法。 Electrical exploration is a geophysical exploration method for prospecting and studying geological structures based on the electrical properties of rocks and ores (such as electrical conductivity, electrochemical activity, electromagnetic induction and dielectric properties, the so-called "electrical differences"). . Electrical exploration is divided into two categories: direct current method (including resistivity method, charging method, natural electric field method and DC induced polarization method) and alternating current method (including AC induced polarization method, electromagnetic method, earth electromagnetic field method, radio). Wave fluoroscopy and microwave method, etc.). The high-density electrical method is developed on the basis of the conventional electrical method. Compared with the conventional electrical method, it has the advantages of low cost, high efficiency, rich information, convenient interpretation, and strong exploration capability. The high-density electrical method refers to the DC high-density resistivity method, but since the DC-induced polarization method is developed therefrom, it is collectively referred to as a high-density electrical method.

目前高密度电法测量***按照接入及布线方式的不同分为两类：集中式高密度电法测量 ***和分布式高密度电法测量***。其中集中式高密度电法测量***所采用的电缆为多芯多抽头高密度电缆（以下简称 "集中式电缆 ")，分布式高密度电法测量***所采用的电缆为分布式智能电缆（以下简称 "分布式电缆")。如图 1，集中式电缆的每根线芯与一个抽头连接，抽头与电极连接，从而实现电极与电极交换装置的连接，因此线芯的数量至少等于电极上数量，线芯的长度为电极至电极交换装置的长度。若每个抽头需同时接入两种类型的电极，那么线芯的数量要增加一倍，电缆重量也将大大增加，因此集中式***一般只进行电阻率测试而不进行激电测试。分布式电缆将发射和接收回路所需要的线芯，以总线形式分布在高密度电缆里，横跨所有的抽头，同时在每个抽头上嵌入交换电路，将与电极相导通的抽头交换连接到发射回路、接收回路或空回路上。采用此种方式能够有效减少电缆中线芯的数量，但分布式电缆需要在每个抽头内集成交换电路，因此抽头的结构设计十分复杂，完全依赖手工生产，效率较低且造价昂贵。若单个抽头损坏，整根电缆都将无法使用，替换成本高。此外，无论是集中式***还是分布式***，在进行大电流测试时，均需加大电缆内线芯的线径，从而增大了电缆的体积与重量。 At present, high-density electrical measurement systems are divided into two categories according to different access and wiring methods: centralized high-density electrical measurement system and distributed high-density electrical measurement system. The cable used in the centralized high-density electrical measurement system is a multi-core multi-tap high-density cable (hereinafter referred to as "centralized cable"), and the cable used in the distributed high-density electrical measurement system is a distributed intelligent cable (below Referred to as "distributed cable"). As shown in Figure 1, each core of the centralized cable is connected to a tap, and the tap is connected to the electrode to realize the connection between the electrode and the electrode exchange device. Therefore, the number of cores is at least equal to the number of electrodes, and the length of the core is the electrode to The length of the electrode exchange device. If each tap needs to be connected to both types of electrodes at the same time, the number of cores will be doubled and the cable weight will be greatly increased. Therefore, centralized systems generally only perform resistivity tests without performing an IP test. The distributed cable connects the cores required for the transmitting and receiving loops in a high-density cable in the form of a bus, spanning all the taps, and embedding a switching circuit on each tap to exchange the taps that conduct the electrodes. To the transmit loop, receive loop or empty loop. In this way, the number of cores in the cable can be effectively reduced. However, the distributed cable needs to integrate the switching circuit in each tap. Therefore, the structure of the tap is very complicated, completely dependent on manual production, and the efficiency is low and the cost is high. If a single tap is damaged, the entire cable will be unusable and the replacement cost will be high. In addition, Whether it is a centralized system or a distributed system, when performing large current tests, it is necessary to increase the wire diameter of the inner core of the cable, thereby increasing the volume and weight of the cable.

地震测试时，每个检波器均需要大线电缆（以下简称 "大线"）中的两个线芯构成一个回路，如图 2。很明显，回路的总线长会随着测点的不同而发生变化，故不同回路受到的噪声干扰和线阻差异较大，所得测试结果的精确度受到影响。考虑到大线的重量和体积，目前使用最为广泛的是规格为 24芯 12通道。采用这种电缆进行测试时，离设备最远的检波器和最近的检波器相比，测量回路的长度相差 11倍，意味着两个通道被环境噪声干扰的强度、接入到主机的电缆的线阻都相差 11倍，从而导致不同通道之间的一致性得不到保证。对于高精度的地震测试，这种误差是非常可观的。 In the earthquake test, each detector needs two cores in the large-line cable (hereinafter referred to as "large line") to form a circuit, as shown in Figure 2. Obviously, the bus length of the loop will change with the different measuring points, so the noise interference and line resistance of different loops are different, and the accuracy of the obtained test results is affected. Considering the weight and volume of the large line, the most widely used is the 24-core 12-channel. When testing with this cable, the length of the measuring loop differs by 11 times compared to the nearest detector, which means that the strength of the two channels is disturbed by environmental noise, and the cable connected to the host. The line resistances are 11 times different, resulting in unmatched consistency between the different channels. For high-precision seismic testing, this error is significant.

另外，当测试较长或超长的测试面时，往往采用分布式测线***，即通过多台设备覆盖断面并进行测量，如图 3。因此各分布设备之间的有效通信，对于提高测试效率有着十分重要的意义，否则每台设备都必须有专业人员进行操作维护，各设备上的测试数据依靠手工拷贝方式进行汇总处理，效率会很低。并且，地震勘探是通过仪器检测、记录人工激发地震的反射波、折射波的传播时间、振幅、波形等以获取相关数据，因此对时间的同步性要求高，因此必须具备专门的同步功能。传统的测试中每台设备均需专人进行控制，因此在时间上难以达到较高的同步性。设备与设备之间往往采用无线通讯的数据传输方式，易受周围环境的影响与干扰，稳定性不强。 In addition, when testing long or long test surfaces, a distributed line measurement system is often used, that is, the sections are covered and measured by multiple devices, as shown in Fig. 3. Therefore, effective communication between distributed devices is of great significance for improving test efficiency. Otherwise, each device must be professionally operated and maintained. The test data on each device is processed by manual copying, and the efficiency will be very high. low. In addition, seismic exploration is to detect and record the reflected waves of artificially excited earthquakes, the propagation time, amplitude, and waveform of the oscillated waves to obtain relevant data. Therefore, the synchronization of time is required, so it is necessary to have a special synchronization function. In the traditional test, each device needs to be controlled by a dedicated person, so it is difficult to achieve high synchronization in time. The data transmission mode of wireless communication is often used between the device and the device, which is susceptible to interference and interference from the surrounding environment, and the stability is not strong.

电法和地震方法虽然在技术原理上完全不同，但是在施工布置和测试方法上，有一定的相似性。它们都需要在连续的测试断面上，按照一定的间隔布置一定数量的电极或检波器，并采用特制的多芯电缆将电极或检波器接入到测试主机。对于更长的测试面，通常采用有多套独立的***进行分布式测量，或者使用更大更长的电缆，覆盖整个测试区域，连接所有的电极或传感器。实际测试中，考虑到电缆的体积和重量，因此必须限制电缆的长度和芯数. 随着各类物探应用逐渐向更大范围、更长断面、更深、更偏远的区域发展，对于物探仪器***也提出了很大的挑战。一方面要求设备能够覆盖到更大的测试范围和更长的测试断面，另一方面还要求设备体积更小、重量更轻，更便于携带和搬运。 Although the electrical and seismic methods are completely different in terms of technical principles, there are certain similarities in the construction layout and test methods. They all need to arrange a certain number of electrodes or detectors at regular intervals on a continuous test section, and use a special multi-core cable to connect the electrodes or detectors to the test host. For longer test surfaces, multiple independent systems are typically used for distributed measurements, or larger and longer cables are used to cover the entire test area and connect all electrodes or sensors. In the actual test, considering the volume and weight of the cable, it is necessary to limit the length of the cable and the number of cores. As various types of geophysical applications are gradually developed to larger, longer, deeper, and more remote areas, for geophysical instrument systems. It also presents a big challenge. On the one hand, the device is required to cover a larger test range and a longer test section, and on the other hand, the device is required to be smaller, lighter and more portable and easy to carry.

具体实施方式 detailed description

为了更好的说明本发明，现结合实施例及附图作进一步的说明。 In order to better illustrate the present invention, further description will be made in conjunction with the embodiments and the accompanying drawings.

实施例 1：多功能双向高密度电缆应用于高密度电阻率测试 Example 1: Multi-function bidirectional high-density cable for high-density resistivity testing

多功能双向高密度电缆应用于电阻率测试时，其总线线芯作为发射回路、接收回路、通信回路和供电回路覆盖所有电极，电缆头中的电极交换装置将测试需要的发射和接收回路分别与抽头对应的 10〜12根线芯中的某一根交换连接，从而对电极进行选择。由于发射回路和接收回路与抽头 /电极之间存在不确定性，因此，电极能全部接入电极交换装置并续接到主机上。本实施例在用于测试较长断面时，可将电缆首尾逐一相连，大大减少了设备重量，野外作业时更为便捷。同时，单根电缆长度较短，在做滚动测试时步长较小，盲区较小，测量深度较深，适用于滚动测试。本发明的电极交换装置集中在电缆头部分，因此抽头的结构简单，制作成本低，生产效率高。由于线缆部分与电极交换装置在结构上完全隔离，因此当电缆出现磨损、内部线路断开而报废时，只需要更换线缆部分，成本较低。 When the multi-functional bidirectional high-density cable is used in the resistivity test, the bus core covers all the electrodes as the transmitting loop, the receiving loop, the communication loop and the power supply loop, and the electrode switching device in the cable head separates the transmitting and receiving loops required for the test respectively. One of the 10 to 12 cores corresponding to the tap is exchanged to select the electrode. Due to the uncertainty between the transmit and receive loops and the tap/electrode, the electrodes can all be connected to the electrode exchange and continue to the mainframe. In the embodiment, when testing for a long section, the cables can be connected one by one, which greatly reduces the weight of the equipment and is more convenient in field operations. At the same time, the length of a single cable is short, the step size is small when doing the rolling test, the blind zone is small, and the measurement depth is deep, which is suitable for rolling test. Since the electrode exchange device of the present invention is concentrated in the cable head portion, the structure of the tap is simple, the manufacturing cost is low, and the production efficiency is high. Since the cable portion is completely isolated from the electrode exchange device, when the cable is worn out and the internal circuit is disconnected and discarded, only the cable portion needs to be replaced, and the cost is low.

实施例 2 : 多功能双向高密度电缆应用于激电测试 Example 2: Multi-functional bidirectional high-density cable used in IP test

本实施例采用本发明双向交换功能，在配合多功能双向高密度电缆进行测试时，可将发射电极挂接在 P1上，接收电极挂接在 P2上。当测试主机需要将某个电极作为发射电极时，该电极的前端交换装置，会将电极交换连接到发射回路上，当需要该电极作为接收电极时，则由电极后端的交换装置，将电极交换到接收回路上。在不增加线芯和电缆的情况下，实现了激电高密度测试要求。 In this embodiment, the bidirectional switching function of the present invention is adopted. When testing with a multi-functional bidirectional high-density cable, the transmitting electrode can be attached to P1, and the receiving electrode is attached to P2. When the test host needs to use an electrode as the transmitting electrode, the front end switching device of the electrode connects the electrode exchange to the transmitting circuit. When the electrode is required as the receiving electrode, the electrode is exchanged by the switching device at the rear end of the electrode. Go to the receiving loop. The requirements for high-density testing of the induced voltage are achieved without adding cores and cables.

实施例 3 : 多功能双向高密度电缆应用于地震测试 Example 3: Multifunctional bidirectional high density cable for seismic testing

将电缆的一端接入仪器主机，另一端通过跳线连接，接入一组检波器，由此构成一个回路。设抽头数量为 N，间距为 L，测点 M所构成的回路总线长 Y为： Connect one end of the cable to the instrument main unit, and the other end is connected by a jumper to access a group of detectors, thus forming a loop. Let the number of taps be N and the spacing be L. The loop bus length Y formed by the measuring point M is:

Y=N*L+(M+N*L-M)=2NL Y=N*L+(M+N*L-M)=2NL

可见，回路总长恒为 2NL，与测点的位置无关。因此，本发明在用于地震测试时，每个回路所受到的干噪声扰和线阻差异小。 It can be seen that the total length of the loop is always 2NL, regardless of the position of the measuring point. Therefore, the present invention is less susceptible to dry noise and line resistance per loop when used in seismic testing.

当所测断面较长时，本发明也适用于分布式测量***。如图 6，电缆一端接入仪器主机，另一端接入接线盒，将分布的所有地震仪主机连接起来。如图 7，接线盒能够识别并处理测试信号，在测试阶段，接线盒将每条电缆的总线交换到抽头上，从而形成检波器的测试回路，并且每个检波器的回路长度是完全一致的。在测试结束后，接线盒能将总线切换到通信模块上，完成设备间的数据传输。通过这种方式，只需要一人对一台主机进行控制，时间上的同步性高。同时，使用电缆内部的总线进行数据传输不仅使数据传输更为便捷，也能提高数据的准确度和可靠性。 The invention is also applicable to distributed measurement systems when the measured profile is long. As shown in Figure 6, one end of the cable is connected to the instrument main unit, and the other end is connected to the junction box to connect all the distributed seismograph hosts. As shown in Figure 7, the junction box can identify and process the test signal. During the test phase, the junction box exchanges the bus of each cable to the tap to form the test loop of the detector, and the loop length of each detector is exactly the same. . After the test is finished, the junction box can switch the bus to the communication module to complete the data transfer between the devices. In this way, only one person needs to control one host, the same time High step. At the same time, the use of the bus inside the cable for data transmission not only makes data transmission more convenient, but also improves the accuracy and reliability of the data.

此外，在电法测试中，考虑到实际测试中发射回路需要持续地承载发射电流，而任意一个抽头作为发射电极的次数是很少的，即实际工作中的载空比要远低于发射回路总线。因此考虑电流承载能力时，电缆上与抽头连接的线芯线径，可以仅仅是发射回路总线的 1/3〜1/4。由此，在根据最大发射电流确定线芯线径时，可减少到抽头的线芯的线径（这类线的数量在电缆里占多数），而提高发射总线的线径。，为了生产加工方便，也可采用多芯相同规格的线芯，但是可以预留一定数量的总线，在交换装置中进行并联，如图 8，从而达到提升电流能力的目的。采用这种技术增加发射回路总线的线径，不仅能提升发射电流的承载能力，还能有效地降低发射回路上的线路电阻，让更多的电流参与到测试发射中，提升测试效率和数据质量。 In addition, in the electrical test, considering the actual test, the transmitting loop needs to continuously carry the emission current, and the number of times any tap is used as the transmitting electrode is very small, that is, the carrier-to-air ratio in actual operation is much lower than the transmitting loop. bus. Therefore, when considering the current carrying capacity, the wire diameter of the cable connected to the tap can be only 1/3 to 1/4 of the transmitting circuit bus. Thus, when the wire diameter is determined based on the maximum emission current, the wire diameter of the wire core to the tap can be reduced (the number of such wires is majority in the cable), and the wire diameter of the transmission bus is increased. In order to facilitate the production and processing, it is also possible to use multi-core cores of the same specification, but a certain number of buses can be reserved, and parallel connection in the switching device, as shown in Fig. 8, to achieve the purpose of improving current capability. Using this technology to increase the wire diameter of the transmitting loop bus can not only improve the carrying capacity of the transmitting current, but also effectively reduce the line resistance on the transmitting loop, allowing more current to participate in the test launch, improving test efficiency and data quality. .

通过将本发明结合不同的设备可实现电阻率测试、激电测试和地震测试。在生产时，只需要一套模具，降低了生产成本。在使用时，不仅只需携带一套电缆设备，而且同一次布置，可进行三种方法的测试，节约了人力、物力以及时间。 Resistivity testing, IP testing, and seismic testing can be accomplished by incorporating the present invention into different devices. At the time of production, only one set of molds is required, which reduces production costs. In use, not only does it only need to carry a set of cable equipment, but in the same arrangement, it can be tested in three ways, saving manpower, material resources and time.
