Description

Technical Field

[0001] The invention relates to the field of petroleum exploitation, and in particular to an energy spectrum saturation reservoir dynamic detector. Background Art

[0002] As is known, energy spectrum refers to the distribution curve of counting rate versus particle energy obtained by energy calibration of pulse amplitude. In the process of oil extraction, in order to detect the remaining amount and saturation of oil inside the underground oil reservoir, it is necessary to send the energy spectrum detection instrument underground along the wellbore through a traction device. In order to avoid friction between the instrument and the side wall of the wellbore, the instrument is placed as close to the center of the wellbore as possible through the straightening mechanism. Then, the specific information of the underground oil can be obtained through the detector, and the decision on whether to continue extraction is made based on the information obtained.

[0003] For example, the Chinese patent document with the authorization announcement number CN215860129U, the announcement date 2022-02-18, and the name "A turbine and Doppler complementary horizontal well production logging instrument and logging system" includes a straightening short section and a sensor short section fixedly connected to the right end of the straightening short section; the straightening short section includes a connecting rod, a first shaft ring and a second shaft ring sleeved on the connecting rod, at least three support arms hinged between the first shaft ring and the second shaft ring, and at least three straightening springs fixedly connected between the first shaft ring and the second shaft ring; a Doppler flow sensor is arranged on the sensor short section; and an optical fiber holding rate sensor probe and a micro-turbine rotor flow sensor are fixedly installed on the support arm. The logging system includes a logging instrument, a first centering device, a second centering device, a flexible short section, a cable connector, and a bottom nose. The patent adopts a very compact structural design and uses new sensor technology to integrate dozens of data measurement and acquisition channels to achieve precise measurement.

[0004] The shortcomings of the above-mentioned prior art are that the straightening mechanism provides prestress to the inner wall of the wellbore through the spring, so that the straightening mechanism is always in contact with the inner wall of the wellbore. However, when adapting to wellbores of different sizes, the compression amount of the spring will be different. At this time, the pressure of the straightening mechanism on the inner wall of the wellbore cannot be constant. That is, when the radial dimension of the wellbore is larger, the compression amount of the spring is smaller, and the prestress on the wellbore is also smaller, so that the supporting force of the straightening mechanism is smaller, and the instrument cannot be maintained in the center position of the wellbore. When the radial dimension of the wellbore is smaller, the compression amount of the spring is greater, and the prestress on the wellbore is greater, so that the resistance encountered by the instrument during transportation becomes greater. Summary of the invention

[0005] The purpose of the present invention is to provide an energy spectrum saturation reservoir dynamic detector to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: The energy spectrum saturation reservoir dynamic detector comprises a rod body and a detection mechanism arranged on the rod body for measuring oil saturation.

[0016] In the above technical scheme, the energy spectrum saturation reservoir dynamic detector provided by the present invention, the first elastic member is used to drive the straightening rod to abut against the inner wall of the wellbore, and to store force on the second elastic member. After the second elastic member completes the force storage (the amount of force stored by the first elastic member on the second elastic member is the same each time), the force of the first elastic member is released. At this time, only the second elastic member abuts against the wellbore. Since the amount of force stored by the second elastic member each time is certain, the abutment force against different wellbore inner walls can be approximately at a constant value.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] In the description of the present invention, it is to be understood that the terms “center”, “longitudinal”, “lateral”, “length”, “width”, “degree”, “up”, “down”, “vertical”, “horizontal”, “inside”, “outside”, “clockwise”, “counterclockwise”, “axial”, “radial”, “circumferential”, etc., indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] Reference Figure 1-12 The energy spectrum saturation reservoir dynamic detector provided in the embodiment of the present invention comprises a rod body 1 and a detection mechanism arranged on the rod body 1 for measuring oil saturation. The rod body 1 is also provided with a straightening mechanism for supporting the rod body 1. The straightening mechanism comprises a sleeve 2 slidably arranged on the rod body 1, a straightening rod 3 is hinged on the sleeve 2, a first elastic member 4 is arranged between the sleeve 2 and the rod body 1, and the straightening mechanism also comprises a second elastic member 5; the first elastic member 4 is used to drive the straightening rod 3 to abut against the inner wall of the wellbore and store force on the second elastic member 5, and after the second elastic member 5 completes the force storage, the force of the first elastic member 4 is released.

[0023] Specifically, the rod body 1 is cylindrical, and the detection mechanism can be an energy spectrometer, which is arranged at the end of the rod body 1 and is sent to the inside of the oil well through a traction device, wherein the traction device includes a straightening mechanism, and the straightening mechanism includes two sleeves 2 slidably arranged on the rod body 1, and the two sleeves 2 are hinged with straightening rods 3, and the ends of the two straightening rods 3 close to each other are hinged to each other, and elastic structures such as springs are arranged between the sleeves 2 and the rod body 1. In the process of sending the detection mechanism into the oil well, the elastic force provided by the spring makes the hinged position of the two straightening rods 3 abut against the inner wall of the well, and the elastic force of the spring makes the straightening rods 3 as much as possible in the middle part of the well, so as to avoid the friction between the detection mechanism and the inner wall of the well as much as possible, and then the detection mechanism can measure the saturation of the remaining oil in the oil well, and evaluate whether to continue mining based on the measured results. This is a prior art and will not be repeated. One of the core innovations of the embodiment of the present invention is that in the sleeve 2 A first elastic member 4 is arranged between the rod body 1 and the rod body 1, and a second elastic member 5 is arranged on the straightening rod 3. The first elastic member 4 and the second elastic member 5 are preferably springs. The first elastic member 4 is used to adjust the angle between the two straightening rods 3, and the distance between the second elastic member 5 and the inner wall of the shaft can be adjusted through the straightening rod 3. The second elastic member 5 is used to provide the straightening rod 3 with an abutment force on the inner wall of the shaft. The effect of such a setting is that the first elastic member 4 is used to drive the straightening rod 3 to abut against the inner wall of the shaft and store force for the second elastic member 5. After the second elastic member 5 has stored force (the amount of force stored by the first elastic member 4 on the second elastic member 5 is the same each time, that is, the length of compression of the second elastic member 5 is the same each time), the force of the first elastic member 4 is released. At this time, only the second elastic member 5 abuts against the shaft. Since the amount of force stored by the second elastic member 5 each time is certain, the abutment force of the second elastic member 5 on the inner walls of shafts of different sizes can be approximately at a constant value.

[0024] Preferably, there are multiple groups of the straightening rods 3. Two straightening rods 3 hinged to each other form one group, and the straightening rods 3 are preferably four groups, and each group of the straightening rods 3 is bent toward the direction of the central axis of the rod body 1, and the four groups of the straightening rods 3 are arranged at intervals of 90° in the circumferential direction of the sleeve 2. By providing multiple groups of the straightening rods 3, the straightening effect on the rod body 1 can be improved.

[0025] Furthermore, a hinge shaft 6 is arranged between the straightening rods 3, a through hole 7 is arranged on the hinge shaft 6, an abutment rod 8 is slidably arranged inside the through hole 7, the second elastic member 5 is arranged between the abutment rod 8 and the hinge shaft 6, and a locking member for fixing the position of the sleeve 2 is arranged between the sleeve 2 and the rod body 1. Specifically, the hinge shaft 6 is arranged at the position where the two righting rods 3 of a single group are hinged, and the two righting rods 3 are hinged to the hinge shaft 6. The hinge shaft 6 is provided with an extension portion in the direction close to the central axis of the rod body 1. The through hole 7 is arranged along the radial direction of the hinge shaft 6 and is connected to the internal space of the extension portion. The end of the abutment rod 8 is located outside the through hole 7, and the radial dimension of this position is larger than the radial dimension of the through hole 7. The second elastic member 5 is arranged between the extension portion and the abutment rod 8. The elastic force of the first elastic member 4 is larger than the sum of the elastic forces of multiple second elastic members 5. The locking member can be a structure such as a latch, which is arranged along the radial direction of the rod body 1 and the sleeve 2. When the latch is plugged into the two at the same time, the rod body 1 and the sleeve 2 cannot slide relative to each other, so that the position of the sleeve 2 can be locked. The purpose of locking is that when dealing with wells of different sizes, one of the sleeves 2 is pulled in the direction away from the other sleeve 2. At this time, each group of straightening rods 3 will swing in the direction away from the central axis of the rod body 1, thereby driving the abutment rod 8 to move toward the inner wall of the well. At this time, the inner wall of the well will provide a reaction force to the abutment rod 8, so that the abutment rod 8 slides relative to the through hole 7 toward the central axis of the rod body 1 and accumulates force for the second elastic member 5. After the second elastic member 5 has accumulated force, the position of the sleeve 2 is locked by the locking member. At this time, the elastic force of the first elastic member 4 will no longer act on the straightening rod 3, that is, the force between the abutment rod 8 and the inner wall of the well is constant to the elastic force stored in the second elastic member 5.

[0026] As another embodiment of the present invention, a rotating seat 9 is provided on the abutment rod 8, and an abutment wheel 10 is provided on the rotating seat 9. Specifically, the rotating seat 9 is fixed to one end of the abutment rod 8 away from the central axis of the rod body 1, and is preferably a U-shaped structure, and two abutment wheels 10 are rotatably provided inside a single rotating seat 9. The effect of such a setting is that, in this embodiment, the force generated by the abutment between the abutment rod 8 and the inner wall of the well is converted into the force between the abutment wheel 10 and the inner wall of the well, so that the sliding friction between the abutment rod 8 and the inner wall of the well can be converted into rolling friction, so as to reduce the resistance of the rod body 1 during operation.

[0027] Furthermore, a sliding block 11 is slidably provided on the straightening rod 3 , and a lap plate 12 is rotatably provided between the rotating seat 9 and the sliding block 11 . Specifically, a slide groove 13 is provided on the surface of the straightening rod 3 away from the rod body 1, and the slider 11 is slidably connected to the slide groove 13. A rotating shaft is provided on the slider 11, and a rotating shaft is also provided at the end of the rotating seat 9. The two ends of the lap plate 12 are rotatably connected to the two rotating shafts respectively, and two lap plates 12 are symmetrically arranged on each group of straightening rods 3, and the two lap plates 12 are arranged inclined. The purpose of such a setting is that when there are impurities such as stones in the well, the lap plates 12 will abut against the impurities, thereby providing the abutment rod 8 to slide in the direction of the rod body 1 through the lap plates 12 and the rotating seat 9, and accumulating force for the second elastic member 5, and driving the slider 11 to slide along the slide groove 13, and driving the lap rod to swing in the direction of the rod body 1, so as to achieve avoidance. When the avoidance is completed, the elastic force of the second elastic member 5 is released, which will drive the abutment rod 8 to slide in the opposite direction, and drive the lap plate 12 to swing in the opposite direction to achieve reset.

[0028] It should be noted that, due to the unlimited position structure of the above-mentioned hinge shaft 6, the hinge shaft 6 is prone to self-rotation during the movement of the rod body 1, which will cause the rotating seat 9 and the abutment wheel 10 to swing, thereby reducing the stability of the straightening mechanism. Furthermore, the two abutment rods 8 are slidably connected. Specifically, for the symmetrically arranged abutment rods 8, the ends thereof away from the rotating seat 9 are slidably connected to each other, that is, one of the abutment rods 8 is provided with a telescopic groove inside, and the end of the other abutment rod 8 is slidably connected to the telescopic groove. In order to avoid interference with another set of symmetrical abutment rods 8, the abutment rods 8 can be arranged as follows. Figure 3 As shown in the arrangement, a cross-shaped avoidance hole 14 is opened on the rod body 1, and the axial length of the avoidance hole 14 on the rod body 1 is greater than the horizontal movement distance of the hinge shaft 6. The effect of such a setting is that under the action of the sliding connection between the symmetrical abutment rods 8, the hinge shaft 6 can be prevented from rotating itself, so as to achieve the effect of limiting the hinge shaft 6, and the distance between the hinge shafts 6 can be adapted through the action of the sliding connection between the abutment rods 8, that is, when the hinge shaft 6 moves in the direction away from the rod body 1, the sliding part of the abutment rod 8 will be extended as a whole, and when the hinge shaft 6 moves in the direction close to the rod body 1, the sliding part of the abutment rod 8 will be shortened as a whole, and when the first elastic member 4 adjusts the angle between the straightening rods 3, the abutment rod 8 will be offset along the rod body 1 toward the direction of the sleeve 2, and due to the existence of the avoidance hole 14, the interference between the abutment rod 8 and the rod body 1 can be avoided.

[0029] As an alternative to the above-mentioned latch for fixing the position of the sleeve 2, the locking member includes a card plate 15 arranged on the rod body 1, and a card block 16 is slidably arranged on the sleeve 2, and the card block 16 has a first position away from the card plate 15 and a second position engaged with the card plate 15; and also includes a power component for driving the card block 16 to switch between the first position and the second position. Specifically, the card plate 15 is arranged on the outer peripheral surface of the rod body 1, which is a structure composed of multiple tooth-like structures. A movable groove 17 is opened inside the sleeve 2, and the card block 16 is slidably arranged in the movable groove 17. Its size is adapted to the gap between adjacent teeth. The power component can be a reciprocating drive component such as a cylinder. The purpose of such a setting is that when the angle between the straightening rods 3 needs to be adjusted, the card block 16 is in the first position. At this time, the card block 16 is far away from the card plate 15. At this time, the sleeve 2 can slide under the elastic force of the first elastic member 4, and will drive the abutment wheel 10 to abut against the inner wall of the wellbore, thereby accumulating force on the second elastic member 5. After the second elastic member 5 has completed the force accumulation, the card block 16 is driven by the power component to switch from the first position to the second position. At this time, the card block 16 is inserted into the card plate 15. At this time, the position of the sleeve 2 is locked, and the elastic force of the first elastic member 4 cannot act on the abutment wheel 10, so as to realize the active switching of the card block 16 between the first position and the second position.

[0030] It should be noted that as the underground detection depth increases, its temperature also gradually increases, so it is very necessary to reduce the use of electrical equipment. As another embodiment of the present invention, the power assembly includes a transmission rod 18 slidably arranged inside the sleeve 2, and the abutment rod 8 is provided with a first abutment portion 19 and a second abutment portion 20. The transmission rod 18 is located on the movement stroke of the first abutment portion 19 and the second abutment portion 20. The block 16 is elastically arranged on the transmission rod 18. An abutment plate 21 is arranged inside the sleeve 2, and an abutment block 22 is arranged on the transmission rod 18. The abutment plate 21 is located on the movement stroke of the abutment block 22. A third elastic member 23 is arranged between the sleeve 2 and the transmission rod 18. Specifically, the first abutting portion 19 and the second abutting portion 20 are both concave structures arranged on the outer circumferential surface of the abutting rod 8, and a stepped structure is formed between the two, and the second abutting portion 20 is located behind the movement stroke of the first abutting portion 19, and the transmission rod 18 includes a first section 33 and a second section 34 that are rotatably connected to each other, and an arc section is arranged at the end of the first section 33, and the arc section is located on the movement stroke of the first abutting portion 19 and the second abutting portion 20, and a connecting shaft 24 is arranged between the straightening rod 3 and the sleeve 2, and the first section 33 is rotatably connected to the connecting shaft 24, and the second section The third elastic member 23 is rotatably connected to the first section 33, and the second section 34 is an elastic telescopic rod. A convex ring or the like is provided between the first section 33 and the second section 34 to prevent the first section 33 from moving relative to the second section 34 along the connecting shaft 24. A space for the transmission rod 18 to move axially along the connecting shaft 24 is provided inside the straightening rod 3. The third elastic member 23 is preferably a spring. One end of the third elastic member 23 is fixedly connected to the movable groove 17, and the other end is fixedly connected to the second section 34. The cross section of the block 16 is T-shaped, and is slidably arranged at the second section 34 away from the first section 3 3, a fourth elastic member 25 is arranged between the elastic arrangement, that is, the block 16 and the second section 34, and the fourth elastic member 25 is also preferably a spring. A protrusion 26 is arranged on the rod body 1, and a mounting groove 27 is opened inside the protrusion 26. The card plate 15 is arranged inside the mounting groove 27, and the inner wall of the movable groove 17 blocks the opening part of the mounting groove 27. A wedge surface is arranged on the abutment plate 21, and the wedge surface is located on the movement stroke of the abutment block 22. The effect of such a setting is that when the elastic force of the first elastic member 4 is released to drive the abutment wheel 10 to abut against the inner wall of the well, it will make The abutting rod 8 moves toward the rod body 1, and drives the first abutting portion 19 and the second abutting portion 20 to move synchronously, so that the first abutting portion 19 abuts against the arc segment on the first section 33, thereby driving the first section 33 to move along the width direction of the straightening rod 3, and under the action of the limit assembly, drives the second section 34 to move along the width direction of the straightening rod 3. At this time, the inner wall of the movable groove 17 will install the opening of the groove 27, so that the end of the block 16 abuts against the inner wall of the movable groove 17, and the third elastic member 23 and the fourth elastic member 25 are synchronously charged.At this time, the elastic force of the first elastic member 4 is continuously released, and drives the abutment rod 8 to continue to slide along the hinge shaft 6, and drives the second abutment portion 20 to abut against the arc segment, and at this time, the second segment 34 will be driven to move further, and the abutment block 22 will be driven to abut against the abutment plate 21, thereby driving the second segment 34 to extend, so that the end of the clamping block 16 is located in the open position of the mounting groove 27. At this time, the elastic force of the fourth elastic member 25 is released to drive the clamping block 16 to move toward the direction of the clamping plate 15, and will make the clamping block 16 and the clamping plate 15 clamped, so as to passively lock the position of the sleeve 2. At this time, only the second elastic member 5 provides the abutment wheel 10 to abut against the well. The force is applied to maintain the constant pressure between the abutment wheel 10 and the well. When the oil well inspection is completed, the device is pulled out of the oil well. At this time, the elastic force of the second elastic member 5 is released to drive the abutment rod 8 to move away from the rod body 1. When the second abutment portion 20 is away from the arc segment, the elastic force of the third elastic member 23 is released, driving the second segment 34 to move in the opposite direction for a distance. At this time, the abutment block 22 and the abutment plate 21 will be driven away synchronously. At this time, the second segment 34 shrinks, and at the same time, the clamping block 16 and the clamping plate 15 are away. At this time, the passive unlocking of the sleeve 2 is realized, so that the sleeve 2 can slide axially along the rod body 1 to prepare for the next traction.

[0031] In summary, the elastic force of the first elastic member 4 has the following strokes when it is released: first, the stroke of driving the abutment wheel 10 to abut against the inner wall of the well through the straightening rod 3; second, the stroke of driving the first abutment portion 19 to abut against the arc segment to store force for the fourth elastic member 25; third, the stroke of driving the abutment block 22 to abut against the abutment plate 21 to drive the second section 34 to extend and insert the clamping block 16 into the clamping plate 15. The advantage of this is that when the clamping block 16 moves to the mounting groove 27 When the sleeve 2 is in the open position, the elastic force of the fourth elastic member 25 is released, thereby realizing the delayed locking effect of the sleeve 2. When the abutment wheel 10 is driven by the elastic force of the first elastic member 4 to abut against the inner wall of the shaft, it is simultaneously passively locked. When the abutment rod 8 shakes slightly when the abutment wheel 10 abuts against impurities, as long as the first abutment portion 19 is not away from the arc segment, the block 16 will not be pulled out of the clamping plate 15, so as to improve the stability of the sleeve 2 when it is locked.

[0032] As another embodiment of the present invention, the abutment rod 8 includes a third section 35 and a fourth section 36 which are rotatably connected, the third section 35 is provided with a first rotating rod 28, a toggle rod 30 is rotatably provided on the rotating seat 9, a second rotating rod 29 is provided on the toggle rod 30, the second rotating rod 29 is located on the movement range of the first rotating rod 28, a protrusion 31 is provided on the third section 35, an inclined groove 32 is provided on the hinge shaft 6, and the protrusion 31 is slidably connected to the inclined groove 32. Specifically, the first abutting portion 19 and the second abutting portion 20 are both arranged on the fourth section 36, the toggle rod 30 is arranged at the opening on the side of the rotating seat 9, and the toggle rod 30 is made of elastic material, that is, it has the ability to self-recover after being bent by force, and the toggle rod 30 is arranged in front of the movement stroke of the abutting wheel 10, the first rotating rod 28 is fixedly connected to the outer circumference of the third section 35, and the second rotating rod 29 is L-shaped, and its vertical section is rotatably connected to the side wall of the rotating seat 9, and passes through the side wall of the rotating seat 9 and is fixed to the toggle rod 30, and its horizontal section is located at On the rotation stroke of the first rotating rod 28, elastic structures such as torsion springs (not shown) are respectively arranged between the vertical section of the second rotating rod 29 and the rotating seat 9, and between the third section 35 and the fourth section 36. The protrusion 31 is cylindrical and is fixedly connected to the outer circumference of the third section 35. The inclined groove 32 is opened on the inner side wall of the hinge shaft 6, which includes a sliding section and an inclined section. The sliding section is arranged vertically, and the inclined section is on the inner circumference of the through hole 7 and is arranged obliquely along the axial direction of the through hole 7. The two ends of the third section 35 are respectively connected to the rotating seat 9 and the fourth section 36 for rotation. The third section 35 is connected to the rotating seat 9 and the fourth section 36, and both ends of the third section 35 are provided with limit blocks or other limit structures for preventing separation. The effect of such a setting is that when the abutment rod 8 slides along the through hole 7 to lock the position of the sleeve 2, the protrusion 31 will be driven into the sliding section. When encountering granular impurities such as stones, the impurities will provide a force for the abutment rod 8 to slide toward the rod body 1 through the lap plate 12 or the abutment wheel 10, so that the protrusion 31 enters the interior of the inclined section, which will cause the third section 35 to rotate itself, thereby driving The first rotating rod 28 rotates synchronously, and during the rotation of the first rotating rod 28, it will abut against the second rotating rod 29, which will make the second rotating rod 29 synchronized, and then drive the toggle rod 30 to rotate synchronously, so as to passively push the impurities to both sides to reduce the obstruction of the impurities and accumulate force in the torsion spring. When cleaning is completed, the elastic force of the torsion spring drives the third section 35 and the toggle rod 30 to automatically reset. When encountering hard impurities, the toggle rod 30 itself will be deformed to adapt, and when passing over the impurities, it will automatically recover under the action of its own elastic force.
