Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
The simplified block diagram of portable test according to embodiments of the present invention and service chamber is illustrated with reference to Fig. 1, Fig. 1.
As it is shown in figure 1, portable test according to embodiments of the present invention includes coaxial hub, main friendship and auxiliary alternating current source, 35Hz power supply with service chamber. Main friendship and auxiliary alternating current source are used for powering to logger with 35Hz power supply. Owing to logger needs when normal operation to obtain the electric power from various power supplys from well logging ground-based system, so in the prior art the test of logger and maintenance will be relied on ground system, this is clearly inconvenience. Because the huge and inconvenient movement of plane system primarily. In this case, if it is desired to multiple loggers are tested being accomplished by mobile huge ground system and coordinate test and maintenance, and this is clearly inconvenience. Secondly, when test and maintenance, logger itself is in off working state, at this moment itself is likely to the power supply with ground logging system and disconnects, thus supply of electric power cannot be obtained. But, logger cannot be tested when unregulated power supply. Above 2 will be brought great inconvenience to test and maintainer.
Therefore, portable test according to embodiments of the present invention and service chamber include logger needs the various power supplys of use and light portable, mobility is good, this makes this portable test and service chamber can support LEAP800 routine open hole well instrument test (including HSTG instrument) when not against ground system, Image-forming instrument test (includes array acoustic, array induction, dipole sonic, microresistivity scans, ultrasonic well week imaging) etc., and test and it can be moved and test and overhaul the instrument being positioned at diverse location by maintainer easily.
In one embodiment, 35hz can include 35Hz power board. In one embodiment, it is possible to by coaxial hub, 35Hz power board, external computing device, logger are coupled together. In one embodiment, coaxial hub can use coaxial line with the connection of logger. One that uses coaxial hub in the test according to the present invention with service chamber is advantageous in that, it can by logger one network of composition of the test of 35Hz power supply, external computing device and needs and maintenance, in order to is controlled by this network and transmits data. Each discrete parts that cannot form network in prior art is combined by this, improves test and the efficiency of maintenance.
In one embodiment, coaxial hub, 35Hz power board, external computing device, TCP/IP procotol can be used to communicate between logger. It will be appreciated by those skilled in the art that the communication protocol that communication uses is not limited to TCP/IP procotol, it can use any suitable communication protocol.
In one embodiment, external computing device can be computer, includes but not limited to notebook, desk computer, tablet PC. External computing device can also is that have calculating and the processor of data-handling capacity, intelligent handheld device etc. Sum it up, every may be used for processes the external computing device that the parts of data, equipment and system can serve as in the present invention. External computing device can pass through coaxial hub and coaxial line and instrument communication to be measured, thus controls the data of instrument and collection instrument.
As described above, in order to test logger, exporting with satisfied in all cases to the test of logger and maintenance from various power supplys can be provided to logger to be tested according to the portable test of the present invention with service chamber. Therefore, the control of various power supplys has just been become the key character of test and service chamber.
Due to logger typically require execution various types of well loggings, therefore to voltage, electric current, frequency needs widely. Such as, wherein 35Hz power supply is generally used for laterolog, and its output needs finely to regulate to meet various landform demand, and main friendship and auxiliary alternating current source power principally for various instruments. Therefore, the output adjustment of power supply is also required in different ways.
The simplified block diagram of portable test according to embodiments of the present invention and the main friendship in service chamber and auxiliary alternating current source is illustrated referring to Fig. 2, Fig. 2.
As in figure 2 it is shown, main friendship and auxiliary alternating current pressing element have the alternating current of common input 220VAC, 50Hz. In order to provide different output, main friendship and auxiliary alternating current source can have manual voltage regulator, thus can by the output of test and maintainer's main friendship of manual adjustments as required and auxiliary alternating current source, thus providing different inputs for logger to be measured. The pressure regulator in main friendship and auxiliary alternating current source can be each independent, as shown in Figure 2. And, the main friendship shown in Fig. 2 and auxiliary alternating current source and pressure regulator are merely illustrative of, and those skilled in the art should understand that the power supply that can also adopt other forms and regulate the form of voltage. In one embodiment, the output of 0 to 250VAC, 1A, 50Hz can be exported respectively through the adjustment of pressure regulator, main friendship and auxiliary alternating current source. It should be appreciated by those skilled in the art that the output in main friendship and auxiliary alternating current source can be the same or different.
The simplified block diagram of 35Hz power supply according to embodiments of the present invention is illustrated with reference to Fig. 3, Fig. 3.
As it is shown on figure 3, this 35Hz power supply can also have and the main input giving auxiliary alternating current pressure identical, the i.e. alternating current of 220VAC, 50Hz. Such benefit is apparent: can simplify device structure, saves space. Therefore, in order to output 35Hz power supply output, this 35Hz power supply can include input tranformer, output transformator, for control input tranformer and output the 35Hz voltage controller of transformator, 35Hz power board. Wherein, 35Hz voltage controller is connected with 35Hz power board, input tranformer and output transformator respectively, and 35Hz power board is connected with external computing device further through coaxial line hub. So, external computing device can be controlled 35Hz voltage controller by 35Hz power board and and then be controlled the output of power supply by 35Hz voltage controller. Therefore, in one embodiment of the invention, the output of 35Hz power supply can by external computing device control, thus reach to power supply output intense adjustment.
In sum, test and maintainer just only can be controlled power supply output, collection instrument data by an external computing device, be controlled instrument etc., and this obviously substantially increases test and the efficiency of maintenance.
In one embodiment of the invention, logger is LEAP800 logger. It will be understood, however, to one skilled in the art, that test and service chamber according to the present invention may be used for test and overhaul other kinds of logger.
Describe specific embodiments of the invention although above-mentioned already in connection with accompanying drawing, but those skilled in the art are without departing from the spirit and scope of the present invention, it is possible to the present invention is carried out various change, amendment and equivalent substitution. It is to say, the scope of the present invention is not limited to above-mentioned exact embodiment. These changes, amendment and equivalent substitution all mean and fall within the spirit and scope that appended claims limits.
