Description
Technical Field
The invention belongs to the technical field of geophysical exploration, relates to a transient electromagnetic probe tube borehole internal pushing technology required by a borehole transient electromagnetic method, and particularly relates to a method and a device for acquiring data in a cable transient electromagnetic probe tube borehole.
Background
The transient electromagnetic method is based on the Faraday electromagnetic induction phenomenon, excites an underground target body by manually establishing an electromagnetic field, and then realizes the detection purpose by adopting a receiving device to observe an induction secondary field of the target body. The transient electromagnetic method plays an important role in underground water detection, mineral exploration, geological and environmental investigation and engineering geological problem solving, and is an important geophysical detection method. According to different working places, the method is divided into a ground transient electromagnetic method and a mine transient electromagnetic method. The two are respectively excited and collected in the ground and the mine roadway. Due to the fact that social infrastructure is rapidly developed, electromagnetic noise sources such as ground transmission lines, residential areas and communication signal towers are visible everywhere, and various ironware such as heading machines, anchor net anchor rods and pipelines in underground roadways are difficult to avoid. The interference sources influence the normal implementation of the ground and mine transient electromagnetic method, and the accuracy of the detection result is reduced.
To avoid the above disadvantages, the borehole transient electromagnetic method, in which the receiving device is disposed in the borehole, or both the transmitting device and the receiving device are disposed in the borehole, has become a method of development potential. Because the drill hole is positioned in the stratum and is closer to the target body, the electromagnetic sensor can acquire stronger abnormal signals while avoiding the interference of electromagnetic noise. The innate advantages of working devices make this approach a hot spot for recent research. Meanwhile, how to push the probe tube containing the receiving device or the transmitting device into the drill hole becomes a key for restricting the implementation of the method.
For vertical drilling or large-angle inclined drilling, the transient electromagnetic probe can enter the drilling by taking gravity as a power source. When the inclination angle of the drill hole is small or horizontal, a special thrust force is required to be applied as a power source to feed the probe into the drill hole.
The probe tube is connected with the short section carbon fiber rod, the pushing force is manually applied to the carbon fiber rod at the orifice, the probe tube is continuously connected with the new short section carbon fiber rod, and the probe tube can be gradually pushed into a drill hole. The method is suitable for near-horizontal drilling, and the maximum pushing distance is about 200 m. When the hole wall collapses or is not smooth, the hole is easy to clamp, and the risk of losing the probe exists. The invention patents with application numbers CN201810963701.3, CN201520843764.7, and CN201520844702.8 are related to or improved to some extent from the above-mentioned pushing method, but do not solve the disadvantages and risks of such methods.
In order to solve the pushing problem of transient electromagnetic probe pipes in a near-horizontal hole, the canadian CRONE company attempts to realize long-distance pushing by using a combination of a hollow drill rod, a slurry pump and a hole bottom anchor. Firstly, pushing a hollow and inner flat drill rod to the bottom of a hole; a hole bottom anchor with a piston is placed at an orifice in the drilling hole, and the rear end of the hole bottom anchor is connected with a pulley and a pull rope; pumping the hole bottom anchor to the bottom of the drill hole by using a slurry pump to fix the hole bottom anchor; connecting the transient electromagnetic probe with a pull rope, and enabling the probe to enter the bottom of a drilled hole by pulling two ends of the pull rope; gradually taking out part or all of the drill rods to ensure that no ferromagnetic material exists near the probe tube, so as to meet the requirement of a transient electromagnetic detection environment; and pulling the pull rope to enable the probe to be positioned at different positions in the drill hole, and carrying out transient electromagnetic data acquisition. The method can realize the pushing of the transient electromagnetic probe in the nearly horizontal and long-distance drill hole, and has the risk that the long-distance pull rope is easy to wind, and the probe is lost due to power failure. In addition, because the probe tube is not protected by an outer layer, the probe tube is easy to block the hole due to collapse or unsmooth hole wall, and the risk of probe loss is generated.
The invention patent with the application number of CN201910520299.6 provides a mining drilling hole radar fine detection device and method based on drilling machine pushing. According to the device, two ends of a cableless drilling radar instrument are respectively connected with a non-metal non-conductive drill rod, then the front end of the cableless drilling radar instrument is connected with a drill bit, the rear end of the cableless drilling radar instrument is connected with a metal drill rod, and the drilling radar instrument is pushed in a drilled hole through the pushing of a drilling machine to the drill rod. The patent can realize the pushing distance larger than 500 m. The drilling radar instrument adopts a working mode of automatically acquiring data without cable connection, so that the drilling radar instrument is not suitable for transient electromagnetic probe tubes with cables. And because the two ends of the probe tube are directly connected with the non-metal non-conducting drill rod, the transient electromagnetic probe tube is easily damaged because the transient electromagnetic probe tube cannot bear the propelling force and the rotating force in the pushing process.
According to the current development situation of the transient electromagnetic instrument for drilling holes, a probe tube for collecting data is connected with a receiver through a cable. Borehole transient electromagnetic data acquisition is carried out in vertical drilling or large-angle inclined drilling, and lowering and recovery of the probe can be carried out through an armored communication cable. The current propelling movement technique can not have cable transition electromagnetism probe propelling movement to longer distance drilling inside, and main limited reason is power, card hole risk and conducting medium influence. The pushing method using the carbon fiber rod has limited power and can not push for a long distance, the risk of hole clamping exists, and the carbon fiber rod is a conductive medium and can not meet the requirement of transient electromagnetic data acquisition; when the hole bottom anchor is used, the pull rope is easy to wind and loses the function of pulling the probe tube, and the probe tube is placed in the bare hole, so that the risk of hole blocking exists; the probe pipe is directly connected with the drill rod for pushing, the probe pipe bears the thrust and the torsion in the pushing process and is easy to damage, and the common drill rod is a metal medium and cannot meet the requirement of transient electromagnetic data acquisition. Therefore, several pushing methods disclosed currently do not fully consider the pushing requirement of the transient electromagnetic probe with cable, and cannot complete the task of pushing and collecting data.
