Description

Technical Field

[0001] The present invention relates to the technical field of low-carbon natural gas exploitation, and specifically to a high-pressure cement injector. Background Art

[0002] When conducting low-carbon exploitation of natural gas, before exploitation, geological exploration needs to be carried out through drilling to obtain relevant information about the underground gas reservoir, such as the depth, thickness, distribution range, gas composition, etc. of the gas reservoir, so as to accurately determine the reserves and exploitation plan of natural gas. Drilling is to establish a passage from the ground to the underground gas reservoir for subsequent exploitation operations. Natural gas is exploited to the ground through the wellbore. At the same time, in some exploitation technologies, such as horizontal well technology, a horizontal well section can be formed in the gas reservoir through drilling to increase the contact area of the gas reservoir and improve the single-well production. After drilling is completed, cement slurry needs to be injected between the well wall and the casing to form a cement sheath. The cement sheath can seal the formation, prevent the collapse of the well wall, protect the stability of the wellbore, and at the same time can also isolate the fluids in different formations to avoid mutual interference between formations. Injecting cement can ensure the sealing performance of the wellhead device and the wellbore, prevent natural gas from leaking into the formation or the ground, and reduce greenhouse gas emissions, which is crucial for achieving low-carbon exploitation. If natural gas leaks, it will not only cause waste of resources, but also lead to greenhouse gases such as methane entering the atmosphere and exacerbate climate change.

[0003] However, when the existing high-pressure cement injectors are in use, the cement mostly fills along the gaps in the soil, which is not uniform enough, resulting in uneven reinforcement effects. At the same time, the cement has a poor wrapping effect on soil particles, thus affecting the reinforcement effect; when grouting, the flow velocity of the cement in the grouting pipe may be uneven locally, easily causing the slurry to accumulate in some parts while spreading insufficiently in other parts; when grouting, the cement easily overflows from the top of the drill hole, making it difficult to maintain a stable grouting pressure and also affecting the reinforcement effect.

[0004] Therefore, we propose a high-pressure cement injector. Summary of the Invention

The movement of the first moving plate 202 is pushed by a third pushing mechanism. Start the power device 104, so that the cement in the hopper 102 enters the grouting pipe 107 through the pump body 101, the discharge port 103 and the hose 106, and enters the annular cover 11. At this time, the sealing disc 207 is in a sealed state. Under the action of hydraulic pressure, the first moving plate 202 can be pushed to move through the moving rod 201. At the same time, the fixing plate 204 and the first insertion rod 13 are driven to move through the first telescopic mechanism, so that the first insertion rod 13 can extend out along the first round hole 12 and be inserted into the soil of the foundation structure.

[0036] The second pushing mechanism includes two second moving plates 301 inserted into the first insertion rod 13. The second moving plates 301 are fixedly sleeved on the side wall of the second insertion rod 15. A T-shaped plate 302 is fixedly connected to the side wall of the first moving plate 202.

When the limiting block 205 abuts against the inner wall of the grouting pipe 107, the first insertion rod 13 stops moving. When the moving rod 201 and the first moving plate 202 continue to move, the T-shaped plate 302 can be driven to continue moving. At the same time, the first spring 403 is compressed.

An inclined surface 604 is provided at the top of the pushing block 603. The lifting mechanism drives the lifting plate 601 to move upwards, and the installation plate 602 drives the plurality of pushing blocks 603 to move upwards. When the inclined surface 604 abuts against the bottom of the first moving plate 202, the first moving plate 202 can be pushed to slide downwards along the inclined surface 604, thereby pushing the first moving plate 202 to move and reset in a direction away from the first circular hole 12. At this time, the first spring 403 gradually resets.

First, drill holes in the soil. After the drilling is completed, rotate and adjust the universal ball 803 to adjust the angle of the grouting pipe 107 and insert the grouting pipe 107 into the drilled hole. Then, start the second motor 805. The rotation of the second motor 805 drives the rotation of the first rubber wheel 806, so as to be able to push the grouting pipe 107 downward, making the movement of the grouting pipe 107 more convenient and fast. And after the grouting is completed, the second motor 805 can be started to reverse, driving the first rubber wheel 806 to reverse, so as to be able to push the grouting pipe 107 upward, making it more convenient and fast to use.

[0042] The sealing mechanism includes a fixed ring 901 fixedly sleeved on the side wall of the universal ball 803.

At the same time, drive the rubber ring 904 to move downward and abut against the top of the drilled hole. At this time, the top of the grouting hole can be sealed to prevent the overflow of cement, achieving a pressure maintaining effect and maintaining a stable grouting pressure, which can improve the injection effect of cement.

[0043] The vibration mechanism includes a fixed block 1002 fixedly connected to the bottom of the fixed ring 901. A circular guide rail 1003 is fixedly connected to the side wall of the fixed block 1002. A rotating ring 1004 is rotatably connected to the side wall of the circular guide rail 1003. A second support block 1005 is fixedly connected to the bottom of the rotating ring 1004. A T-shaped guide rod 1006 is inserted into the side wall of the second support block 1005.

During grouting, the third motor 1001 is started. The rotation of the third motor 1001 drives the rotation of the second rubber wheel 1010, so as to drive the rotating ring 1004 to rotate along the side wall of the circular guide rail 1003, and drive the T-shaped guide rod 1006 to rotate synchronously through the second support block 1005. When the T-shaped guide rod 1006 abuts against the side wall of the tapered block 1009, it can push the T-shaped guide rod 1006 to move away from the tapered block 1009. At the same time, the fourth spring 1008 is compressed. When the T-shaped guide rod 1006 passes over the tapered block 1009, the T-shaped guide rod 1006 can move back to its original position under the action of the fourth spring 1008 and strike the side wall of the grouting pipe 107 to form a vibration effect. In this way, the T-shaped guide rod 1006 can repeatedly knock and vibrate the side wall of the grouting pipe 107. The vibration can make the flow rate of the slurry in the grouting pipe 107 more uniform. Under the action of the vibration, the viscosity of the slurry will decrease and the fluidity will increase, so that the slurry can more fully fill the small pores and cracks, improve the fullness and compactness of grouting, and improve the injection effect of cement.

[0044] Working principle: When in use, during the low-carbon exploitation of natural gas, first drill holes in the soil, start the drive motor 1606, the rotation of the drive motor 1606 drives the rotation of the drill pipe 1607 and the drill bit 1608. At the same time, the first lifting module 1602 drives the moving block 1603 and the rotating plate 1605 to move downward, and at the same time, drives the drill pipe 1607 and the drill bit 1608 to move downward to achieve the drilling operation. And before drilling, the adjustment motor 1604 can be started, and the rotation of the adjustment motor 1604 drives the rotation of the rotating plate 1605, so as to facilitate the adjustment of the drilling angle. After the drilling is completed, pull out the drill pipe 1607 and the drill bit 1608 upward. Then, rotate and adjust the universal ball 803 to adjust the angle of the grouting pipe 107 and insert the grouting pipe 107 into the drilled hole. Then, start the second motor 805, and the rotation of the second motor 805 drives the rotation of the first rubber wheel 806, so as to be able to push the grouting pipe 107 downward, making the movement of the grouting pipe 107 more convenient and fast.

[0045] After the grouting pipe 107 is inserted in place, energize the electromagnet 705. After the electromagnet 705 is energized, it attracts the iron block 706, so that the lifting plate 601 moves downward, and at the same time, drives the mounting plate 602 and the pushing block 603 to move downward. At this time, the pushing block 603 is separated from the first moving plate 202, and at the same time, the third spring 704 is compressed. Then, start the power device 104, so that the cement in the hopper 102 enters the grouting pipe 107 through the pump body 101, the discharge port 103 and the hose 106, and enters the annular cover 11. At this time, the sealing disk 207 is in a sealed state. Under the action of hydraulic pressure, the first moving plate 202 can be pushed to move through the moving rod 201. At the same time, the fixed plate 204 and the first plug rod 13 are driven to move through the first telescopic mechanism, so that the first plug rod 13 can extend out along the first round hole 12 and insert into the soil of the foundation structure. When the limiting block 205 abuts against the inner wall of the grouting pipe 107, the first plug rod 13 stops moving. When the moving rod 201 and the first moving plate 202 continue to move, the T-shaped plate 302 can be driven to continue to move. At the same time, the first spring 403 is compressed, and the pushing pin 304 slides along the inclined groove 303, so as to be able to push a plurality of second plug rods 15 to extend out along the second round hole 14 and insert into the soil of the foundation structure. At the same time, the second spring 503 is stretched.

[0046] Next, cut off the power supply of the electromagnet 705. At this time, the lifting plate 601 can move upward and reset under the action of the third spring 704, and drive the plurality of pushing blocks 603 to move upward through the mounting plate 602. When the inclined surface 604 abuts against the bottom of the first moving plate 202, it can push the first moving plate 202 to slide downward along the inclined surface 604, thereby pushing the first moving plate 202 to move and reset in a direction away from the first round hole 12. At this time, the first spring 403 gradually resets. At the same time, the second insertion rod 15 can retract into the first insertion rod 13 along the second round hole 14 under the action of the second spring 503, and the push pin 304 moves and resets along the inclined groove 303. After the first spring 403 is reset, when the first moving plate 202 continues to move, the first telescopic mechanism and the fixing plate 204 can drive the first insertion rod 13 to retract into the annular cover 11 along the first round hole 12.

[0047] Then, start the first motor 206 to drive the sealing disc 207 to rotate and open, so that the cement in the annular cover 11 can be injected into the drilling hole, and can be filled in the jack formed after the first insertion rod 13 and the second insertion rod 15 are inserted, improving the injection volume of the cement, improving the injection effect of the cement, enabling the cement slurry to form a more uniform distribution in the soil, avoiding the slurry concentrating in certain areas and resulting in uneven reinforcement effects. At the same time, the slurry can better wrap the soil particles, improving the bonding force and frictional force between the soil particles, thereby enhancing the overall strength and stability of the soil.

[0048] After grouting for a period of time, the air in the drilling hole is discharged. Then, drive the moving ring 903 to move downward through the second lifting module 902, and at the same time, drive the rubber ring 904 to move downward and abut against the top of the drilling hole. At this time, the top of the grouting hole can be sealed to prevent the overflow of cement, achieving a pressure-holding effect, maintaining a stable grouting pressure, and improving the injection effect of the cement.

[0049] Meanwhile, the third motor 1001 is started. The rotation of the third motor 1001 drives the rotation of the second rubber wheel 1010, so as to drive the rotating ring 1004 to rotate along the side wall of the annular guide rail 1003, and drive the T-shaped guide rod 1006 to rotate synchronously through the second support block 1005. When the T-shaped guide rod 1006 abuts against the side wall of the conical block 1009, it can push the T-shaped guide rod 1006 to move away from the conical block 1009. At the same time, the fourth spring 1008 is compressed. When the T-shaped guide rod 1006 passes over the conical block 1009, the T-shaped guide rod 1006 can move back to its original position under the action of the fourth spring 1008 and impact on the side wall of the grouting pipe 107 to form a vibration effect. In this way, the T-shaped guide rod 1006 can repeatedly knock and vibrate the side wall of the grouting pipe 107. The vibration can make the flow rate of the slurry in the grouting pipe 107 more uniform. Under the action of the vibration, the viscosity of the slurry will decrease and the fluidity will increase, so that the small pores and cracks can be filled more fully, improving the fullness and compactness of the grouting and enhancing the injection effect of the cement.
