Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas field well testing operations, and is an electronic casting and catching well testing tool. Background Art

[0002] To meet the needs of recording downhole pressure and temperature data in oil and gas wells, a survey of oil and gas field blocks such as the southern edge of the Xinjiang Oilfield and the Fuman Oilfield in the Tarim Oilfield revealed that currently used electronic casting and fishing well testing tools have certain defects during use. Chinese patent publication No. CN211448582U discloses an electronic de-stuck instrument, which includes a releaser and a hanger. The releaser includes a switch wheel and a switch hook. The switch wheel controls the switch hook to maintain the locking state of the fishing head or release the fishing head. The hanger includes a suspension arm, a tension spring, and a fishing head. The suspension arm includes a suspension arm roller and a suspension arm bracket. The suspension arm roller is activated by the tension spring to be in either a retracted or extended state. During testing, the suspension arm is extended to position the instrument. After the test, the instrument can be easily removed. However, the de-stuck instrument has only one suspension arm. After the releaser and hanger are separated, the suspension arm is prone to contraction after receiving an impact, causing the hanger to move up and down in the well, making it impossible to accurately position the hanger in the well.

[0003] The Chinese patent document with publication number CN216197948U discloses a new type of track-type mechanical de-jamming device, which includes a center rod, one end of which is sleeved with an upper joint, and the outer wall of the center rod is sleeved with a track sleeve, an upper sleeve, a track pin, a lower sleeve, a connecting sleeve, a locking block sleeve, a straightening block, a straightening body sleeve, a spring, a slip sleeve, a slip, a locking block, a vertebral body, a vertebral body spring and a connecting head in sequence. The utility model describes a new type of track-type mechanical de-jamming instrument, which uses mechanical structures such as springs and locking blocks to realize lifting and lowering to release the hanger, which is difficult to operate. It is lifted and lowered three times. When the instrument string is lowered for the fourth time, the track pin enters the last long groove of the track groove, and the vertebral body moves upward and contacts with the slip, and at the same time, the slip is pushed out of the slip sleeve and stuck to the inner wall of the oil pipe. Then the instrument string is lifted, the slip and the locking block sleeve move in position, the locking block is released, the center axis moves and generates axial displacement with the lower locking block sleeve, the releaser hook is released, and the hanger is lost. The number of lifting and lowering times is large, and the hanger is released in a deep well. If the number of times is large, it is easy for the operator to fail in releasing the hanger.

DETAILED DESCRIPTION

[0027] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0028] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 The positional relationships of front, back, top, bottom, left, and right are described in the layout of the manual. Figure 1 The layout direction is determined by the

[0029] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0030] Example 1: As shown in the attached Figures 1 to 4As shown in Figure 11, the electronic well testing tool for casting and fishing includes a pressure gauge, a hanger, a releaser and an electronic de-stuck instrument. The pressure gauge includes a test head 1, a sensor joint 2 and a battery tube 3 fixedly installed together from bottom to top. A pressure probe is installed in the test head 1, a pressure control module is installed in the sensor joint 2, a first power module is installed in the battery tube 3, and a hanger is fixedly installed on the upper end of the battery tube 3. A plurality of lower suspension arms 4 are distributed along the circumference on the inner side of the lower part of the hanger, and a plurality of upper suspension arms 5 are distributed along the circumference on the inner side of the upper part of the hanger. A releaser is detachably installed on the upper part of the hanger, and an electronic de-stuck instrument is installed on the upper part of the releaser. The electronic de-stuck instrument can separate the releaser and the hanger from each other, and after the releaser and the hanger are separated from each other, the lower end of the upper suspension arm 5 and the upper end of the lower suspension arm can extend out of the hanger and abut against the inner wall of the casing. The pressure probe is electrically connected to the pressure control module, and the pressure control module is electrically connected to the first power module.

[0031] According to the requirements, the pressure gauge is a well-known downhole pressure gauge. During use, an upper suspension arm 5 and a lower suspension arm 4 are set in the hanger. After the tool is lowered into the target position in the well, the releaser and the hanger are separated from each other. The lower end of the upper suspension arm 5 and the upper end of the lower suspension arm 4 in the hanger can be quickly extended to abut against the inner wall of the casing, so that the pressure gauge and the hanger can be firmly fixed at the target position in the well. When there is an upward impact, the upper suspension arm 5 can prevent the pressure probe from moving upward, and when there is a downward impact, the lower suspension arm 4 can prevent the pressure probe from sliding downward. The upper suspension arm 5 and the lower suspension arm 4 interact with each other to avoid the problem of a single suspension arm When subjected to impact, it is easy to be retracted, causing the pressure gauge to move up and down in the well. In this way, the upper suspension arm 5 and the lower suspension arm 4 interact with each other to achieve accurate positioning of the suspension tube 6 and the pressure gauge in the well. The modular design of the electronic de-carding device and the releaser facilitates the disassembly and assembly of the equipment. The electronic de-carding device can separate the releaser and the hanger from each other, and after the releaser and the hanger are separated from each other, the lower end of the upper suspension arm 5 and the upper end of the lower suspension arm 4 can extend out of the hanger and abut against the inner wall of the casing, which also makes the separation of the releaser and the hanger simpler and reduces the difficulty of operation.

[0032] The above-mentioned electronic casting and fishing well testing tools can be further optimized and / or improved according to actual needs:

[0033] Example 2: As an optimization of the above example, as shown in the attached Figures 1 to 7As shown in Figure 10, the hanger includes a hanging tube 6, a guide rod, a lower connecting block 8 and an upper connecting block 7. The upper part of the battery tube 3 is fixedly installed with the lower part of the hanging tube 6. The guide rod is installed in the hanging tube 6, and the lower connecting block 8 is installed on the outer side of the lower part of the guide rod. A number of strip-shaped lower guide holes 10 that are connected inside and outside are distributed along the circumference on the outer side of the lower part of the hanging tube 6. A lower hanging arm 4 is installed in each lower guide hole 10. The lower end of each lower hanging arm 4 is hingedly installed with the lower connecting block 8. A lower elastic reset member 9 that is installed on the outer side of the guide rod is provided between the inner side of the lower part of the hanging tube 6 and the lower side of the lower connecting block 8. A strip-shaped unlocking hole 11 that is connected inside and outside is provided on the outer side of the lower part of the hanging tube 6. An unlocking block 12 is slidably installed in the unlocking hole 11. The unlocking block 12 is fixedly installed with the lower connecting block 8. A limiting ring platform 13 is fixed on the outer side of the middle of the guide rod, corresponding to the limiting ring platform 1 3. The upper outer side of the guide rod at the upper end position is sleeved with an upper connecting block 7. The upper outer side of the suspension tube 6 is circumferentially spaced with a number of inner-outer connected strip-shaped upper guide holes 14. An upper suspension arm 5 is installed in each upper guide hole 14. The upper end of each upper suspension arm 5 is hingedly installed with the upper connecting block 7. An upper elastic reset member 15 sleeved on the outer side of the guide rod is provided between the upper inner side of the suspension tube 6 and the upper side of the upper connecting block. The releaser includes a release tube 16 and an unlocking mechanism. The release tube 16 is provided above the suspension tube 6. The release tube 16 is provided with an unlocking mechanism whose lower part is detachably mounted with the upper end of the guide rod. The upper end of the release tube 16 is fixedly mounted with an electronic card removing device. The electronic card removing device can separate the unlocking mechanism and the guide rod from each other. After the guide rod and the unlocking mechanism are separated from each other, the upper part of the upper suspension arm 5 and the lower part of the lower suspension arm 4 can both extend outward.

[0034] According to the requirements, a connecting short section 17 is fixedly installed at the lower part of the suspension tube 6, and the lower part of the connecting short section 17 is fixedly installed together with the upper part of the battery tube 3. The material of the suspension tube 6 can be stainless steel Inconel718 and 17-4PH, which has the advantages of high temperature resistance, high pressure resistance and corrosion resistance. Inconel718 alloy is a precipitation-hardened nickel-chromium-iron alloy containing niobium and molybdenum. It has high strength and good toughness at high temperatures and is corrosion-resistant in high and low temperature environments; 17-4PH stainless steel is a martensitic precipitation-hardened stainless steel, and its corresponding Chinese brand is: 0Cr17Ni4Cu4Nb. 17-4PH is a precipitation-hardened steel with copper added, which can be used normally in oil and gas wells with high temperature (above 200°C), high pressure (above 140MPa) and depth exceeding 7200m. The upper elastic reset member 15 and the lower elastic reset member 9 are both existing well-known compression springs.

[0035] Before going down the well, first press the upper suspension arm 5 and the lower suspension arm 4 into the upper guide hole 14 and the lower guide hole 10, then connect the upper end of the guide rod with the unlocking mechanism, and the upper connecting block 7 falls and seats on the upper end of the limit ring platform 13. At this time, the upper elastic reset member 15 acts on the upper side of the upper connecting block 7, so that the upper suspension arm 5 is retracted into the upper guide hole 14. At the same time, the unlocking mechanism presses the upper side of the unlocking block 12, so that the lower connecting block 8 presses the lower elastic reset member 9 and then moves downward, thus ensuring that the lower suspension arm 4 is retracted into the lower guide hole 10, so that the upper suspension arm 5 and The lower suspension arms 4 are all in a retracted state, which is convenient for lowering into the well. When the target position in the well is reached, the unlocking mechanism and the guide rod are separated from each other, and the guide rod falls after the tension disappears. The upper connecting block 7 loses the support of the limit ring 13 and moves downward under the action of the upper elastic reset member 15. The lower end of the upper suspension arm 5 is quickly extended and abuts against the inner wall of the casing. At the same time, the lower connecting block 8 moves upward under the action of the lower elastic reset member 9, and the upper end of the lower suspension arm 4 is quickly extended and abuts against the inner wall of the casing, thereby realizing the fixation of the suspension tube 6 in the casing, which is convenient for pressure collection operations.

[0036] Example 3: As an optimization of the above embodiment, as shown in the attached Figures 1 to 3 As shown in , 5 to 7, and 10, the guide rod includes an upper core shaft 18 and a lower core shaft 19 fixedly installed together from top to bottom, the lower connecting block 8 is sleeved on the outer side of the lower core shaft 19, and the outer side of the lower part of the lower core shaft 19 is sleeved with a lower plug 20 fixedly installed on the inner side of the lower part of the suspension tube 6, the lower elastic reset member 9 is installed between the upper side of the lower plug 20 and the lower side of the lower connecting block 8, the upper connecting block 7 is sleeved on the outer side of the upper core shaft 18, and the outer side of the upper part of the upper core shaft 18 is sleeved with an upper plug 21 fixedly installed on the inner side of the upper part of the suspension tube 6, the upper elastic reset member 15 is installed between the lower side of the upper plug 21 and the upper side of the upper connecting block 7, the limiting ring 13 is fixedly installed on the outer side of the lower and upper core shafts 19, corresponding to the upper plug 2 1. A fixing sleeve 22 is sleeved on the outer side of the upper core shaft 18 at the upper position above the fixing sleeve 22. A plurality of inner mounting holes that are connected inside and outside are evenly spaced along the circumference of the outer side of the fixing sleeve 22. An outer mounting hole that is connected inside and outside is provided on the upper outer side of the hanging tube 6 corresponding to the position of each inner mounting hole. A hanging shear nail 23 with the end portion located in the corresponding inner mounting hole is screwed into each outer mounting hole. A hanging rod 24 is fixedly installed on the upper end of the upper core shaft 18 corresponding to the position above the hanging tube 6.

A keyhole 27 with an upper end extending to the upper end of the hanging tube 6 is provided on the upper inner wall of the unlocking hole 11 corresponding to the position of the unlocking block 12.

[0037] According to requirements, the upper plug 21 and the lower plug 20 can both be inner ring platforms fixed to the inner side of the suspension tube 6, or can be screwed to the inner side of the suspension tube 6.

During use, the guide rod includes an upper core shaft 18 and a lower core shaft 19 which are fixed together from top to bottom, so as to facilitate the assembly between the guide rod and the suspension tube 6. By setting a fixing sleeve 22 and a suspension shear nail 23, the guide rod and the suspension tube 6 can be installed together, which is convenient for the subsequent salvage operation of the suspension tube 6. By setting a key hole 27, during installation, a long rod inserted into the key hole 27 is installed at the lower end of the release tube 16, so that the lower end of the long rod and the upper side of the locking block 26 are abutted against each other, that is, the lower suspension arm 4 can be retracted into the lower guide hole 10, which is convenient for the suspension tube 6 to be lowered into the well.

The upper guide holes 14 and the lower guide holes 10 are staggered, so that the lower end of the upper suspension arm 5 and the upper end of the lower suspension arm 4 can be against the inner wall of the sleeve after being extended, and the force is more evenly distributed. The lower inner wall of the upper guide hole 14 is provided with an upper slope 30 that tilts from top to bottom and from inside to outside, and the upper inner wall of the lower guide hole 10 is provided with a lower slope 31 that tilts from top to bottom and from outside to inside. In this way, during the extension and retraction process of the lower end of the upper suspension arm 5 and the upper end of the lower suspension arm 4, the upper roller 28 and the lower roller 29 can roll along the upper slope 30 and the lower slope 31, making the movement more gentle and avoiding deformation of the upper suspension arm 5 and the lower suspension arm 4 when the impact is too large.

[0040] Example 5: As an optimization of the above embodiment, as shown in the attached Figure 1 、 5As shown in Figures 7 and 10, the unlocking mechanism includes an unlocking rod 32, a hook 38, a positioning rod 33 and a release slider 34. The upper end of the hanging cylinder 6 is provided with a positioning hole 35 with an opening facing upward, and the lower end of the release cylinder 16 is fixedly installed with a positioning rod 33 and an unlocking rod 32 at intervals. The positioning rod 33 is inserted into the positioning hole 35, and the lower end of the unlocking rod 32 passes through the keyhole 27 and abuts against the upper side of the unlocking block 12. The upper part of the release cylinder 16 is provided with a strip-shaped swinging hole 37 that is connected inside and outside. A hinge shaft 36 is fixedly installed on the inner side of the upper part of the swinging hole 37. The hinge shaft 36 is hingedly installed with the upper part of the hook 38, and the lower part of the hook 38 corresponding to the position below the hinge shaft 36 is provided with a locking groove opening to the left. 39. The lower inner wall of the locking groove 39 is inclined from left to right and from bottom to top. The lower left side of the hook 38 is provided with a hanging surface 40 which is inclined from top to bottom and from left to right. The hanging surface 40 is provided with a guide groove 41 which opens to the left and is connected to the locking groove 39 at the upper end. The guide groove 41 is in an arc shape that matches the hanging rod 24. The hanging head 25 is suspended on the lower inner wall of the locking groove 39. A release slider 34 is provided on the inner side of the upper part of the release cylinder 16. The right side of the lower part of the release slider 34 is abutted against the left side of the upper part of the hook 38. The upper part of the release cylinder 16 is fixedly installed with the lower part of the electronic card remover. The lower part of the electronic card remover is provided with a driving mechanism 46 that can move the release slider 34 up and down.

[0041] According to requirements, a compression spring can be installed between the left side of the hook 38 and the inner wall of the release tube 16 at the position between the bottom of the hinge shaft 36 and the top of the locking groove 39. In this way, after the release slider 34 moves upward, the lower end of the hook 38 can swing to the right under the action of the compression spring, so that the hook 38 and the suspension head 25 are separated from each other, and the release tube 16 and the suspension tube 6 are separated from each other, so that the suspension tube 6, the upper core shaft 18 and the lower core shaft 19 move downward, and the upper elastic reset member 15 and the lower elastic reset member 9 are no longer constrained. After resetting respectively, the lower end of the upper suspension arm 5 and the upper end of the lower suspension arm 4 are extended and rest against the inner wall of the sleeve, and then a pressure test can be performed.

[0042] During installation, the upper end of the hanging head 25 is against the hanging surface 40. When the upper end of the hanging head 25 continues to move upward relative to the hanging surface 40, the hanging head 25 acts on the inclined hanging surface 40, so that the hanging surface 40 is subjected to a force to the right, thereby causing the lower end of the hook 38 to swing outward. When the hanging head 25 continues to move upward into the locking groove 39, the hook 38 is reset under the action of gravity, and the lower end of the hanging head 25 is seated on the lower inner wall of the locking groove 39. Since the lower inner wall of the locking groove 39 is inclined from left to right and from bottom to top, the lower inner wall of the locking groove 39 is subjected to a force to the right, and the lower end of the hook 38 has a tendency to swing outward. Since the lower right side of the release slider 34 is against the upper left side of the hook 38, the hanging head 25 is hung in the locking groove 39.

[0043] When the locking cam 39 is in the upright position, the locking cam 39 is in the upright position, and the locking cam 39 is in the upright position, so that the locking cam 39 is released.

[0044] Example 6: As an optimization of the above embodiment, as shown in the attached Figures 1 to 7 As shown in Figures 10 and 12, the electronic card removal device includes a driving cylinder 42 and a second power supply module, a driving control module and a driving mechanism 46 which are installed in the driving cylinder 42 from top to bottom. A rope cap 43 is fixedly installed on the upper end of the driving cylinder 42, and the lower part of the driving cylinder 42 is fixedly installed with the upper part of the release cylinder 16. A threaded hole is provided in the center of the upper end of the release slider 34, and the lower outer side of the output shaft of the driving mechanism 46 is screwed into the threaded hole. An anti-rotation groove 44 is provided on the outer side of the release slider 34, and a radial anti-rotation hole is provided on the outer side of the release cylinder 16 corresponding to the position of the anti-rotation groove 44. An anti-rotation pin 45 with an end portion located in the anti-rotation groove 44 is fixedly installed in the anti-rotation hole. The second power supply module is electrically connected to the driving control module, and the driving control module is electrically connected to the driving mechanism 46.

[0045] According to the requirements, the driving mechanism 46 is a reduction motor, the driving control module can be an existing well-known DC motor speed regulator, the electronic de-carding device and the releaser can also form an existing well-known electronic de-carding device, and the diameter of the release slider 34 gradually decreases from top to bottom. During use, the release cylinder 16 of the electronic de-carding device is installed together with the suspension cylinder 6 on the ground and then lowered into the target position in the well. Underground, the driving mechanism 46 can be activated by the driving module. When the output shaft of the driving mechanism 46 rotates, the release slider 34 is driven to move up and down. An anti-rotation pin 45 with an end located in the anti-rotation groove 44 is installed in the anti-rotation hole to prevent the release slider 34 from rotating when the output shaft of the driving mechanism 46 rotates. In this way, the release slider 34 can be moved up and down, thereby realizing the disassembly and assembly between the suspension cylinder 6 and the release cylinder 16.

[0046] Example 7: As an optimization of the above embodiment, as shown in the attached Figures 2 to 4As shown in , 8 and 9, it also includes a recovery device for recovering the hanger, which includes an overshot tube 47, a jar 48 and a weighting rod 49 fixed together in sequence from bottom to top. A salvage hole 50 is provided on the inside of the overshot tube 47, which is through-and-through. A conical guide surface 52 with a smaller upper part and a larger lower part is provided on the lower part of the salvage hole 50. A radially through-and-through fixing hole 51 is provided on the outer side of the overshot tube 47 corresponding to the position above the guide surface 52. A rotating pin 53 is fixedly installed in the fixing hole 51, and a hanging block 54 is fixedly installed on the outer side of the rotating pin 53. A limiting block 55 is fixedly installed on the upper left side of the hanging block 54, and a U-shaped hanging groove 56 is provided on the upper right side of the hanging block 54 corresponding to the position of the salvage hole 50, which is through-and-through and opens to the right. The width of the hanging groove 56 is smaller than the diameter of the lower end of the hanging head 25, and a torsion spring 57 is installed between the hanging block 54 and the overshot tube 47, which can make the lower right side of the hanging block 54 abut against the lower inner wall of the fixing hole 51.

[0047] When the pressure gauge is lowered to the target position downhole, the drive control module activates the drive mechanism 46. The drive control module can be controlled by surface equipment using known technology, such as a cable running down the well with the pressure gauge. When the output shaft of the drive mechanism 46 rotates, the release slider 34 moves upward. After the lower end of the release slider 34 moves above the hook 38, the lower end of the hook 38 swings to the right under the gravity of the suspension head 25 or under the action of the compression spring between the hook 28 and the release cylinder 16. The suspension head 25 separates from the locking groove 39 and falls. That is, the upper core shaft 18 and the lower core shaft 19 fall together. When the upper core shaft 18 falls, the limit ring platform 13 no longer supports the upper connecting block 7. The upper elastic reset member 15 acts on the upper side of the upper connecting block 7 after being reset. The upper connecting block 7 begins to move downward, causing the upper roller 28 to move downward along the upward slope 30, and finally causing the upper roller 28 to extend out of the upper guide hole 14 and abut against the inner wall of the sleeve. The upper roller 28 is clamped between the inner wall of the sleeve and the upward slope 30 under the action of the upper elastic reset member 15, and the upper roller 28 fixes the suspension tube 6 in the sleeve through the upper suspension arm 5.

[0048] When the lower core shaft 19 falls, the unlocking rod 32 and the unlocking block 12 are separated from each other, and the lower elastic return member 9 is reset and acts on the lower side of the lower connecting block 8, and under the action of the lower slope 31 and the lower plug 20, the lower connecting block 8 begins to move upward, causing the lower roller 29 to move upward along the lower slope 31, and finally causing the lower roller 29 to extend out of the lower guide hole 10 and abut against the inner wall of the casing. In this way, the lower roller 29 and the upper roller 28 both abut against the inner wall of the casing. Finally, the lower roller 29 is clamped between the inner wall of the casing and the lower slope 31 under the action of the lower elastic return member 9, thereby firmly fixing the suspension tube 6 on the inner wall of the casing, that is, fixing the pressure gauge in the target position in the casing. When there is an upward punch, the upper suspension arm 5 prevents the suspension tube 6 from moving up under the action of the upper elastic return member 15. Similarly, when there is a downward punch, the lower suspension arm 4 prevents the suspension tube 6 from sliding down under the action of the lower elastic return member 9, thereby achieving the positioning effect of the suspension tube 6 and the pressure gauge.

[0049] After the pressure gauge is fixed in the casing, the driving cylinder 42 and the release cylinder 16 are fished out, and the pressure gauge starts to collect data. After the test is completed, the hanging cylinder 6 and the pressure gauge are fished out using the recovery device. The specific process is as follows: according to the wellhead pressure and engineering design, a suitable weighting rod 49 is selected, the rope cap 43 is installed on the upper end of the weighting rod 49, and then the jar 48 is connected. After ensuring that all parts are connected and tightened, the overshot tube 47 is lowered. When the overshot tube 47 is lowered to the top of the hanging tube 6, the overshot tube 47 is slowly lowered. When the hanging head 25 passes through the guide surface 52 and enters the overshot tube 47, it pushes up the lower side of the hanging block 54, so that the hanging tube 47 is lowered. The right part of the hanging block 54 rotates upward (counterclockwise). When the hanging block 54 rotates 90 degrees, the hanging head 25 is located above the hanging block 54. The hanging head 25 no longer acts on the hanging block 54. The hanging block 54 is reset under the action of the torsion spring 57. That is, the lower side of the right part of the hanging block 54 abuts against the lower inner wall of the fixing hole 51. At this time, the hanging head 25 falls and seats on the upper side of the hanging block 54. The hanging head 25 can be connected to the overshot tube 47. In this way, the hanging head 25 can only move up and down above the hanging block 54. Then, the overshot tube 47 is shocked by the jar 48, so that the locking block 26 and the fixing sleeve are locked. 22 interact with each other to cut the hanging shear nail 23. After the hanging shear nail 23 is cut, the fixing sleeve 22 and the hanging tube 6 are separated from each other, and the overshot tube 47 is lowered. The overshot tube 47 and the fixing sleeve 22 move downward. In the process of the fixing sleeve 22 moving to the upper side of the upper plug 21, the limiting ring 13 acts on the upper side of the lower connecting block 8 and makes the lower connecting block 8 move downward, so that the lower suspension arm 4 moves along the downslope 31. Finally, the lower roller 29 is completely retracted to the inside of the hanging tube 6, and then the overshot tube 47 is lifted, and the hanging head 25 moves upward with the overshot tube 47. The hanging head 25 carries the upper core shaft 18 and The lower core shaft 19 moves upward, and the upper core shaft 18 moves upward with the limiting ring platform 13. When the limiting ring platform 13 moves upward, the limiting ring platform 13 acts on the upper connecting block 7 to make the upper connecting block 7 move upward to squeeze the upper elastic reset member 15. After the upper connecting block 7 moves upward, the lower end of the upper suspension arm 5 contracts, and the upper roller 28 no longer abuts against the inner wall of the casing. In this way, the salvage tube 47 is continued to be lifted, and the suspension tube 6 and the pressure gauge can be taken out. After the suspension tube 6 and the pressure gauge are pulled out from the well, wipe them clean, use tools to remove the suspension tube 6 and the pressure gauge, remove the rope cap 43, the weighting rod 49, etc., and put them into the tool box.

[0050] The above technical features respectively constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
