Description

Technical Field

[0001] This invention relates to the field of measurement technology, specifically to a multi-parameter collaborative logging device and method under high temperature and high pressure conditions. Background Technology

[0002] Well logging equipment is a specialized set of instruments used in oil and gas exploration. It primarily determines the location of oil reservoirs and geological parameters through downhole physical information acquisition. Based on application scenarios, it is divided into surface systems and downhole instruments, with downhole instruments including nuclear magnetic resonance logging tools, imaging logging tools, and other types.

[0003] The patent application number CN202022382162.X mentions "a modular replaceable groundwater monitoring well device". This device can be constructed according to the actual site conditions, is convenient, quick, economical and efficient, and is suitable for groundwater monitoring in various environments and with various indicators. When the site use changes, the components can be replaced in time and reused, which reduces construction costs, makes full use of some components, and reduces loss and pollution.

[0004] However, when the above-mentioned device is used for testing, because the whole device is a straight column, if there is a small deformation underground, it is easy for part of it to be stuck due to the protrusion. This part cannot be moved, causing the device to get stuck underground. This sticking makes it difficult to retrieve the device, consumes a lot of time, and also leads to low measurement efficiency. Summary of the Invention

[0005] This invention provides a multi-parameter collaborative logging device and method under high temperature and high pressure environment, which can effectively solve the problem mentioned in the background art that, due to its straight cylindrical shape, if a small deformation occurs underground during detection, a part of the device is easily stuck due to the protrusion and cannot be moved, causing the device to get stuck underground. Furthermore, being stuck will make it difficult to retrieve the device, consume a lot of time, and also lead to low measurement efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-parameter collaborative logging device and method under high temperature and high pressure environment, comprising a detection tube, wherein the detection tube is equipped with a detection protection component, and the detection protection component includes a detection probe; The detection tube contains detection probes placed at intervals, and an isolation ring is placed between adjacent detection probes.

A connecting cable is installed in the middle of the top surface of the outer end cap.

[0007] According to the above technical solution, a guide ring is fixedly sleeved on the outside of the jacking pipe, and a fixing clip is uniformly welded on the outside of the guide ring. A bent rod is symmetrically hinged at the top and bottom of the fixing clip. One end of the two bent rods located on the same fixing clip is rotatably connected to the two ends of the movable clip. An upper guide roller is rotatably installed through the middle of the movable clip.

[0008] According to the above technical solution, the bending rod is composed of two straight rods connected by a spring hinge, and the bending rod, the fixed clip, and the movable clip are combined to form a hexagonal frame.

[0009] According to the above technical solution, a protective film is adhered to the outside of the rubber tube, and the end face of the disassembly ring is a regular dodecagon with a circular hole in the middle.

[0010] According to the above technical solution, threaded grooves are provided on the inner sides of both ends of the detection tube, and the mating external threaded tube and the threaded grooves are connected by threads.

[0011] According to the above technical solution, the inner side of the jacking pipe is uniformly provided with a wire-passing groove. One end of the internal conductor of the connecting cable passes through the wire-passing pipe and the wire-passing groove to connect the detection probe and the crushing motor. The other end of the internal conductor of the connecting cable is connected to the external control console.

[0012] According to the above technical solution, the bottom end of the detection tube located at the bottom is connected to a counterweight detection component, which includes a counterweight block. The top of the counterweight is connected to the bottom of the detection tube by a thread. A motor slot is opened at the top of the counterweight. An active motor is installed inside the motor slot. A winding shaft is connected to the output shaft of the active motor. A wire hole is opened at the bottom of the motor slot near the winding shaft. The counterweight has evenly spaced storage slots on its outer side. A rotating rod is hinged to the bottom of the storage slot. A bottom guide wheel is rotatably mounted on the top of the rotating rod. A pressure groove is formed in the middle of the storage slot. A pressure sensor is embedded inside the pressure groove. One side of the pressure sensor is connected to one end of a compression spring. The other end of the compression spring is connected to the middle of the rotating rod. One end of the rotating rod is connected to a winding rope near the threading hole. The other end of the winding rope is wound around the outside of the winding shaft.

[0013] According to the above technical solution, the top of the counterweight is welded with a bottom connecting screw tube, and the bottom connecting screw tube is connected to the bottom end of the detection tube by thread.

[0014] According to the above technical solution, the input end of the active motor is connected by wires and connecting cables, and the output end of the pressure sensor is connected by a data cable box and connecting cables.

[0015] A method for using a multi-parameter collaborative logging device under high temperature and high pressure conditions, according to the claim, includes the following steps: S1: The assembly device connects adjacent detection tubes with rubber tubes, and alternately places detection probes and isolation rings inside the detection tubes. The bottom of the detection tube is connected to a counterweight, and the top of the detection tube is connected to a top tube. S2: Guiding detection. During the descent, the bottom guide wheel is always in contact with the inner wall of the borehole. The support device keeps the device in the middle of the borehole. Based on the feedback from the pressure sensor, the condition of the inner wall is measured. The upper guide roller on the outside of the jacking pipe also contacts the inner wall of the borehole. S3: Deformation and displacement. When the bottom or top of the device is squeezed, the device will bend at the rubber tube, and the device will change from a straight state to a bent state, so that the device can pass through the protruding position. S4: Pull up the recovery mechanism, start the crushing motor, drive the crushing teeth to rotate, and crush the protruding part during the upward process to expand the blocked drill hole so that the detection tube can pass through at this position.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with a detection and protection component, during the descent process, the upper guide roller on the outside of the jacking pipe also contacts the inner wall of the borehole, and the bending rod will bend at the spring hinge connection, so that the jacking pipe is also in the middle of the borehole, keeping the whole device centered, which facilitates the measurement of each detection probe in the detection pipe, ensuring measurement accuracy and efficiency. During the measurement process, if deformation occurs inside the borehole, the device will bend at the rubber tube when it is squeezed at the bottom or top of the device. The device will change from a straight state to a bent state, thus allowing the device to pass through the protruding position, which facilitates subsequent testing. If the top of the device gets stuck when pulling back the detection device, start the crushing motor. Since the inner and outer end caps are fixedly connected by a conduit and fixedly installed on the top of the top pipe, the crushing motor will drive the driven gear ring to rotate by rotating the driven gear installed on the top surface of the inner end cap, which in turn drives the crushing teeth to rotate. During the upward process, the protruding part will be crushed, the blocked drill hole will be enlarged, and the detection tube can pass through this position, so as to facilitate the quick recovery of the device and avoid the problem of the device being difficult to recover, which would affect the detection and cause property damage. In addition, the device is tightly connected, which can be better used under high temperature and high pressure and protect the internal structure.

[0017] 2. Equipped with a counterweight detection component, the assembled device is placed inside the borehole to be tested. The active motor unwinds the winding spool, and the winding rope is in a relaxed state. Under the action of the compression spring, the rotating rod is pushed away from the receiving groove. During the descent, the bottom guide wheel remains in contact with the inner wall of the borehole, supporting the device and keeping it in the middle of the borehole. In conjunction with the upper guide roller, the device is better kept in the center position, further improving the accuracy of the probe measurement. During the descent, the bottom guide wheel is pushed towards the receiving groove by the protruding inner wall, thus allowing the pressure sensor to detect the protrusion of the borehole inner wall and measure the condition of the inner wall.

[0018] In summary, the detection protection component can replace the detection probe inside the detection tube and install multiple detection tubes to meet various detection and measurement needs. It can be bent according to the conditions inside the borehole to avoid protruding positions and facilitate better descent for detection. The upper guide roller of the detection protection component and the bottom guide roller of the counterweight detection component make the descent of the device more stable and convenient for detection. During retrieval, after the crushing teeth of the detection protection component break the protruding positions, the active motor will wrap the winding rope around the outside of the winding shaft, so that the rotating rod is stored in the storage groove, preventing the rotating rod from obstructing the retrieval of the device. The two components work together to achieve better detection and retrieval results. Attached Figure Description

[0024] The bottom end of the detection tube 1 at the bottom is connected to a counterweight detection component 3. The counterweight detection component 3 includes a counterweight block 301, a motor slot 302, an active motor 303, a winding shaft 304, a wire hole 305, a storage slot 306, a rotating rod 307, a bottom guide wheel 308, a pressure slot 309, a pressure sensor 310, a compression spring 311, a winding rope 312, and a bottom connecting screw tube 313.

[0025] like Figure 7 As shown, a method for using a multi-parameter collaborative logging device under high temperature and high pressure conditions includes the following steps: S1: Assemble the device, then connect the adjacent detection tubes 1 through the rubber tube 222, alternately place the detection probe 201 and the isolation ring 202 into the detection tube 1, connect the bottom end of the detection tube 1 to the counterweight 301, and connect the top end of the detection tube 1 to the top tube 205. S2: Guiding detection. During the descent, the bottom guide wheel 308 is always in contact with the inner wall of the borehole, supporting the device so that the device is in the middle of the borehole. Based on the feedback from the pressure sensor 310, the condition of the inner wall is measured. The upper guide roller 220 on the outside of the jacking pipe 205 also contacts the inner wall of the borehole. S3: Deformation and displacement. When the bottom or top of the device is squeezed, the device will bend at the rubber tube 222, and the device will change from a straight state to a bent state, so that the device can pass through the protruding position. S4: Pull up the recovery, start the crushing motor 207, drive the crushing teeth 212 to rotate, crush the protruding part during the upward process, expand the blocked drill hole, so that the position can pass through the detection tube 1.

[0026] The working principle and usage process of this invention: If there are multiple detection tubes 1, adjacent detection tubes 1 are connected by rubber tubes 222, and the disassembly ring 203 is rotated to fix them. Detection probes 201 and isolation rings 202 are alternately placed in the detection tubes 1. The type of detection probe 201 can be selected as needed, such as ultrasonic probes, temperature probes, electromagnetic probes, etc. The bottom end of the detection tube 1 is connected to the counterweight 301, and the top end of the detection tube 1 is connected to the top tube 205 to form a detection device. When testing is required, the assembled device is placed in the borehole to be tested. The active motor 303 unwinds the winding spool 304, and the winding rope 312 is in a relaxed state. Under the action of the compression spring 311, the rotating rod 307 is pushed away from the storage groove 306. During the descent, the bottom guide wheel 308 is always in contact with the inner wall of the borehole, supporting the device and placing it in the middle of the borehole. During the descent, the bottom guide wheel 308 is pushed towards the storage groove 306 by the protruding inner wall, thereby knowing the protrusion status of the inner wall of the borehole based on the feedback of the pressure sensor 310 and measuring the condition of the inner wall. During the descent, the upper guide roller 220 on the outside of the jacking pipe 205 also contacts the inner wall of the borehole, and the bending rod 218 bends at the spring hinge connection, so that the jacking pipe 205 is also in the middle of the borehole, keeping the whole device centered, which facilitates the measurement of each detection probe 201 in the detection tube 1, ensuring measurement accuracy and efficiency. During the measurement process, if deformation occurs inside the borehole, the device will bend at the rubber tube 222 when it is squeezed at the bottom or top of the device. The device will change from a straight state to a bent state, thus allowing the device to pass through the protruding position, which facilitates subsequent testing. If the top of the device is stuck when pulling back the detection device, start the crushing motor 207. Since the inner end cover 206 and the outer end cover 214 are fixedly connected by the conduit 213 and fixedly installed on the top of the top tube 205, the crushing motor 207 will drive the driven gear ring 211 to rotate by rotating the driven gear 209 installed on the top surface of the inner end cover 206, which in turn drives the crushing teeth 212 to rotate. During the upward process, the protruding part is crushed, the blocked drill hole is enlarged, and the detection tube 1 can be passed through this position, so as to facilitate the quick recovery of the device and avoid the problem of the device being difficult to recover, which affects the detection and property loss. The detection protection component 2 can replace the detection probe 201 inside the detection tube 1 and install multiple detection tubes 1 to facilitate various detection and measurement needs. It can be bent according to the conditions inside the borehole to avoid protruding positions and improve descent for detection. The upper guide roller 220 of the detection protection component 2 and the bottom guide roller 308 of the counterweight detection component 3 make the descent of the device more stable and convenient for detection. During retrieval, after the crushing teeth 212 of the detection protection component 2 crushes the protruding positions, the active motor 303 will wrap the winding rope 312 around the outside of the winding shaft 304, so that the rotating rod 307 is stored in the storage groove 306, preventing the rotating rod 307 from obstructing the retrieval of the device. The two components work together to achieve better detection and retrieval results.

During the descent, the bottom guide wheel (308) is always in contact with the inner wall of the borehole, supporting the device so that the device is in the middle of the borehole. According to the feedback of the pressure sensor (310), the condition of the inner wall is measured. The upper guide roller (220) on the outside of the jacking pipe (205) also contacts the inner wall of the borehole. S3: Deformation and displacement. When the bottom or top of the device is squeezed, the device will bend at the rubber tube (222), and the device will change from straight to bent, so that the device passes through the protruding position. S4: Pull up the recovery, start the crushing motor (207), drive the crushing teeth (212) to rotate, crush the protruding part during the rising process, expand the blocked drill hole, so that the position can pass through the detection tube (1).
