Description
Technical Field

Background
In the process of oil field production and development, along with the process of crude oil exploitation, the stratum energy is gradually reduced, so that the difficulty of crude oil exploitation is gradually increased. In order to keep the stratum energy and improve the exploitation utilization rate of the oil layer, water is injected into the stratum to supplement the loss of the stratum energy, and then the aims of continuously exploiting the oil layer and improving the recovery ratio of the oil layer are achieved. Currently, oilfield flooding can be classified into general flooding, eccentric flooding and concentric flooding. The eccentric water injection and the concentric water injection belong to oil layer separate layer water injection, and different water injection amounts can be supplemented to different oil layers through the oil layer separate layer water injection so as to adjust the energy of the stratum.

In order to better understand the automatic setting mechanism for the concentric seal testing and adjusting instrument in the present application, it will be further explained and illustrated below. As shown in fig. 1, a first shaft 23 extends through the upper end of the housing 4, the first shaft 23 is located at the upper end of the automatic setting mechanism, and the third shaft 12 may extend through the lower end of the housing 4. The upper end of the first shaft 23 is used for connecting a motor and a speed reducer of a concentric seal testing and adjusting instrument, and can also be connected with a corresponding control circuit, a flow testing short joint and the like; and the lower end of the third shaft 12 is used for connecting a flow measuring and regulating device and the like.
As shown in fig. 1, a first expansion mechanism and a second expansion mechanism which can expand in the radial direction are provided on the side wall of the housing 4. The first expansion mechanism may include a first expansion member 6 provided on the first notch of the housing 4, a first fixing member 5 for fixing an upper end of the first expansion member 6; the second expansion mechanism comprises a second expansion piece 10 arranged on the second notch of the shell 4 and a second fixing piece 8 used for fixing the upper end of the second expansion piece 10. The first expansion piece 6 and the second expansion piece 10 can be made of rubber, and when the lower ends of the first expansion piece 6 and the second expansion piece 10 are pushed upwards, the middle parts of the first expansion piece 6 and the second expansion piece 10 can expand in the radial direction, so that the purpose of setting is achieved.
As shown in fig. 1, the first clutch mechanism 20 may include a first shaft 23 penetrating through the housing 4, a clutch sleeve 22 connected to the first shaft 23, a first transmission sleeve 21 capable of contacting the first shaft 23 and transmitting power, a cam 1 capable of being in transmission connection with the first transmission sleeve 21, a second shaft 18 capable of contacting the first shaft 23 and transmitting power, and a first elastic member 24 disposed between the clutch sleeve 22 and the housing 4. The first shaft 23 can slide along the vertical direction, when the first shaft 23 moves upwards, the first shaft 23 is separated from the transmission sleeve, and the first shaft 23 is contacted with the second shaft 18 and can transmit power. When the clutch sleeve 22 moves downwards under the action of the first elastic member 24, the clutch sleeve 22 drives the first shaft 23 to move downwards, the first shaft 23 is in contact with the transmission sleeve and can transmit, and the first shaft 23 is separated from the second shaft 18. When the first shaft 23 contacts with the first transmission sleeve 21 and can transmit, the first shaft 23 drives the first transmission sleeve 21 to rotate, so that the first transmission sleeve 21 drives the cam 1 to rotate.
As shown in fig. 1, the first sliding sleeve 19 abuts against or is connected to the clutch sleeve 22, so that the first sliding sleeve 19 can drive the clutch sleeve 22 to move in the vertical direction. Meanwhile, a positioning mechanism is arranged on the first sliding sleeve 19, and the cam 1 can control the opening and closing of the positioning mechanism. Specifically, the positioning mechanism may include: the positioning device comprises a positioning claw 3 which is hinged with the first sliding sleeve 19 through a positioning shaft 2, and a second elastic piece 25 which is arranged between the positioning claw 3 and the first sliding sleeve 19, wherein the second elastic piece 25 can enable the positioning claw 3 to be opened. The positioning claws 3 can be symmetrically arranged and can be propped against the pipe column to be fixed when being opened. The second elastic member 25 can be a torsion spring, which respectively abuts against the lower end of the positioning pawl 3 and the first sliding sleeve 19, so that the positioning pawl 3 is opened.
As shown in fig. 1, one end of the positioning pawl 3 abuts against the cam 1, and when the long axis of the cam 1 abuts against one end of the positioning pawl 3, the positioning pawl 3 is in a closed state, and when the short axis of the cam 1 abuts against one end of the positioning pawl 3, the positioning pawl 3 is in an open state. Specifically, the upper end of the positioning pawl 3 abuts against the cam 1, when the first shaft 23 drives the cam 1 to rotate and the long shaft of the cam 1 abuts against one end of the positioning pawl 3, the upper end of the positioning pawl 3 moves outwards along the radial direction, the second elastic part 25 contracts, and thus, the lower end of the positioning pawl 3 contracts, and the whole positioning pawl 3 is closed. When the first shaft 23 drives the cam 1 to rotate and the short shaft of the cam 1 abuts against one end of the positioning pawl 3, the upper end of the positioning pawl 3 moves inwards along the radial direction, the second elastic element 25 extends, so that the lower end of the positioning pawl 3 expands outwards, and the whole positioning pawl 3 is opened.
As shown in fig. 1, the second sliding sleeve 16 is screwed on the lower end of the first sliding sleeve 19. The distance between the first runner 19 and the second runner 16 can be adjusted by rotation between the threads. The second clutch mechanism 9 may include a second transmission sleeve 14 disposed on the inner wall of the second sliding sleeve 16, a third sliding sleeve 13 connected to the lower end of the second shaft 18, and a third shaft 12 capable of contacting and transmitting with the third sliding sleeve 13, wherein the third sliding sleeve 13 is capable of contacting and transmitting with the second transmission sleeve. When the third sliding sleeve 13 and the second transmission sleeve 14 are displaced and contacted with each other, the second shaft 18 can drive the third sliding sleeve 13 to rotate, and the third sliding sleeve 13 further drives the second transmission sleeve 14 to rotate, so that the second sliding sleeve 16 rotates, and the distance between the first sliding sleeve 19 and the second sliding sleeve 16 can be controlled later. When the third sliding sleeve 13 is separated from the second transmission sleeve 14, the third sliding sleeve 13 moves downwards to contact with the third shaft 12, so as to transmit with the third shaft 12. At this time, the automatic setting mechanism can drive the testing and adjusting device in the concentric seal testing and adjusting instrument to test and adjust through the third shaft 12.
As shown in fig. 1, a first driving member 7 and a second driving member 11 are disposed on a sidewall of the second sliding sleeve 16, the first driving member 7 is used for driving the first expansion mechanism to expand radially, and the second driving member 11 is used for driving the second expansion mechanism to expand radially. Specifically, the first driving member 7 abuts against the lower end of the first expansion member 6, and when the first driving member 7 moves upward, the first driving member 7 drives the first expansion member 6 to expand radially; the second driving member 11 abuts against the lower end of the second expansion member 10, and when the second driving member 11 moves upward, the second driving member 11 drives the second expansion member 10 to expand radially. When the second transmission sleeve 14 and the third sliding sleeve 13 are in contact and can transmit power, the second shaft 18 can adjust the distance between the first sliding sleeve 19 and the second sliding sleeve 16 through rotation, and when the distance between the first sliding sleeve 19 and the second sliding sleeve 16 is increased, the first driving piece 7 and the second driving piece 11 move downwards along with the second sliding sleeve 16, so that the first expansion piece 6 and the second expansion piece 10 are restored to the unsealing state.
The pressure sensor 17 is used to measure the pressure between the first expansion mechanism and the second expansion mechanism. In one possible embodiment, as shown in fig. 1, a pressure sensor 17 is provided in the second shaft 18, and the pressure sensor 17 communicates with the side wall of the housing 4 between the first expansion mechanism and the second expansion mechanism through a pressure transfer flow passage 15. After the first expansion mechanism and the second expansion mechanism are seated, the pressure sensor 17 can measure the pressure between the first expansion mechanism and the second expansion mechanism, so as to perform a seal checking test.
The application also provides a concentric seal testing and adjusting instrument which comprises any automatic setting mechanism for the concentric seal testing and adjusting instrument.
The specific operation process of the automatic setting mechanism for the concentric seal testing and adjusting instrument is as follows: before the concentric seal testing and adjusting instrument is put into a tubular column, the positioning claw 3 in the automatic setting mechanism is in a closed state. When the whole concentric seal testing and adjusting instrument is put into the upper end of the water distributor of the target layer, an instruction for opening the positioning claw 3 is given. At this time, the first shaft 23 contacts with the first transmission sleeve 21, drives the first shaft 23 to rotate, and transmits the rotation to the cam 1 through the first transmission sleeve 21, and when the short shaft of the cam 1 rotates to abut against the upper end of the positioning pawl 3, the lower end of the positioning pawl 3 is opened under the action of the second elastic element 25. The concentric seal testing and adjusting instrument is put into the water distributor, the positioning claw 3 falls into the water distributor, and the positioning claw 3 is forced upwards under the action of the gravity of the instrument. When the positioning claw 3 is forced upwards, the positioning shaft 2 and the first sliding sleeve 19 are driven to move upwards, the first sliding sleeve 19 pushes the clutch sleeve 22 to move upwards, and the first shaft 23 is further caused to move upwards. This results in the first shaft 23 being separated from the first driving sleeve 21, the first shaft 23 being in contact with the second shaft 18 and being able to drive. When the first shaft 23 rotates, the second shaft 18 can be rotated, and the cam 1 can not rotate any more.
In the process, when the first sliding sleeve 19 moves upwards, the first sliding sleeve 16 is driven to move upwards, the second sliding sleeve 16 moves upwards, the first driving piece 7 and the second driving piece 11 also move upwards, the first driving piece 7 drives the first expansion piece 6 to expand radially, the second driving piece 11 drives the second expansion piece 10 to expand radially, and thus the first expansion piece 6 and the second driving piece 11 realize setting, and at the moment, the instrument can perform a seal testing test. When the first expansion element 6 and the second driving element 11 are expanded to set, the third sliding sleeve 13 is in contact with the rotating sleeve, and the third sliding sleeve 13 is not in contact with the third shaft 12.
After the sealing is finished, the first shaft 23 is controlled to rotate, the first shaft 23 drives the second shaft 18 to rotate, and the second sliding sleeve 16 is further driven to rotate through the third sliding sleeve 13 and the transmission sleeve, because the first sliding sleeve 19 cannot rotate, the second sliding sleeve 16 can rotate to loosen the threads between the second sliding sleeve 16 and the first sliding sleeve 19, the position of the first sliding sleeve 19 is unchanged, the second sliding sleeve 16 moves downwards, the second sliding sleeve 16 drives the first driving piece 7 and the second driving piece 11 to move downwards, so that the first expansion piece 6 and the second expansion piece 10 are reset and unsealed, and meanwhile, the third sliding sleeve 13 is separated from the second transmission sleeve 14. The first shaft 23 continues to rotate, which drives the second shaft 18 to rotate, and further brings the third sliding sleeve 13 into contact with the third shaft 12. At this time, the concentric seal testing and adjusting instrument can drive the testing and adjusting device of the instrument to perform testing and adjusting through the third shaft 12. After the testing and the adjusting are finished, the concentric seal testing and adjusting instrument is lifted upwards, so that the positioning claw 3 is not stressed any more. The first shaft 23 rotates reversely to drive the second shaft 18 to rotate reversely, and the third sliding sleeve 13 is separated from contact with the third shaft 12 and then contacts with the second transmission sleeve 14, so that the second sliding sleeve 16 is screwed with the first sliding sleeve 19. Then, under the action of the first elastic member 24, the clutch sleeve 22 moves downwards, the clutch sleeve 22 pushes the first sliding sleeve 19 and the first shaft 23 to gradually move downwards, and finally the first shaft 23 is separated from the second shaft 18, and the first shaft 23 is in contact with the first transmission sleeve 21 and can transmit, so that the cam 1 can rotate to a position that the long shaft abuts against the upper end of the positioning claw 3 through the rotation of the first shaft 23, so that the positioning claw 3 is closed, the resetting of the automatic setting mechanism is completed through the process, and then the next layer of task of checking, sealing and measuring can be performed.
