Description

Technical Field

[0001] The utility model relates to the technical field of petroleum and natural gas, in particular to a water drainage and gas production wellhead mechanism. Background Art

[0002] The drainage and gas production wellhead mechanism is an important equipment used in oil fields, natural gas fields and other oil and gas fields. Its function is to perform drainage and gas production operations at the wellhead. In the process of oil and gas exploration and development, the wellhead mechanism plays a key role, which can effectively realize the oil and gas production and drainage and sewage discharge in the well, and ensure the efficiency and safety of oil and gas resource extraction.

[0003] The Chinese patent publication number is CN218894640U. It discloses a dense gas well with a rod pump for drainage and gas production wellhead mechanism, which includes a gas production wellhead body, a fixing component is provided at the bottom of the outer side of the gas production wellhead body, and an opening is provided at the end of the telescopic rod at the bottom of the fixing component; the middle part of the outer side of the gas production wellhead body is connected to a card slot. The utility model adopts the above-mentioned dense gas well with a rod pump for drainage and gas production wellhead mechanism, which can prevent the dense gas gas production wellhead device from being easily damaged by falling rocks and other objects, ensure the normal operation of the gas production equipment, and is conducive to the long-term use of the gas production wellhead mechanism.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, the protective component is directly fixedly connected to the gas wellhead body. Once external falling rocks hit the protective component, the impact caused by the impact will be directly transmitted to the gas wellhead body. There is still a risk of damage to the gas inlet body, which makes the protective effect of the protective component not comprehensive, because it cannot completely isolate the external impact force. Therefore, it is necessary to provide a drainage gas wellhead mechanism to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of the utility model is to provide a drainage and gas production wellhead mechanism to solve at least one technical problem existing in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water drainage and gas production wellhead mechanism, comprising:

[0008] The gas inlet body and the ground, an annular guard is arranged on the ground on the outside of the gas inlet body, a plurality of shaping anchor bolts are welded to the bottom of the annular guard, a plurality of diagonal braces are hinged on the inner surface of the annular guard, a pad is fixedly installed on one end of the diagonal brace, a mounting hole is opened on the top of the pad, an inverted cone anchor bolt is inserted into the pad through the mounting hole, and a door body is arranged on the outer surface of the annular guard.

[0009] Preferably, the annular guard and the outer surface of the door body are fixedly installed with a plurality of fixed cylinders, a buffer rod is slidably inserted at one end of the fixed cylinder, a spring is fixedly connected between the end of the buffer rod located inside the fixed cylinder and the inner wall of the fixed cylinder, a symmetrically distributed limit block is fixedly installed on the outer wall of the one end of the buffer rod located inside the fixed cylinder, symmetrically distributed limit grooves are opened on the inner wall of the fixed cylinder, and the limit grooves are slidably connected to the limit blocks, a plurality of anti-collision plates are fixedly installed at one end of the buffer rod located outside the fixed cylinder, and the anti-collision plates are equidistantly distributed on the outside of the annular guard.

[0010] Preferably, a sealing anti-slip sleeve is fixedly installed at one end of the fixed tube, and the sealing anti-slip sleeve is slidably connected to the buffer rod.

[0011] Preferably, the anti-collision plate is in the shape of an arc plate.

[0012] Preferably, the outer surfaces of the annular protective member, the anti-collision plate and the door body are all provided with a wear-resistant coating.

[0013] Preferably, the door body is hinged to the annular protective member, and a lock is provided between the door body and the annular protective member.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model forms a protective structure on the outside of the gas inlet body through the coordinated use of the gas inlet body, the ground, the annular protective member, the pad, the inverted cone anchor bolts, the diagonal brace, the shaped anchor bolts and the mounting holes. Once the external falling rocks hit the annular protective member, the impact force caused by the impact will be directly transmitted to the ground through the annular protective member. Since there is no connecting structure between the annular protective member and the gas inlet body, no matter from which direction the annular protective member is hit, the impact force caused by the impact will not have any effect on the gas inlet body, thereby achieving effective isolation and dispersion of external impact force, improving the comprehensiveness of the protection effect of the annular protective member, and ensuring the stability and safety of the equipment.

[0016] 2. The utility model uses a fixed tube, a buffer rod, an anti-collision plate, a spring, a limit block, a sealing anti-slip sleeve and a limit groove in coordination. When falling rocks from the outside hit the annular protective part, they will directly hit the anti-collision plate on the outside of the annular protective part. After being hit by the falling rocks, the anti-collision plate will move closer to the annular protective part. The movement of the anti-collision plate will drive the buffer rod to slide toward the inside of the fixed tube and squeeze the spring. Through the elastic deformation of the spring, the impact of the falling rocks can be effectively buffered, reducing the damage of the falling rocks to the anti-slip structure, further improving the protective effect of the protective structure, and being conducive to the long-term safe and stable use of the gas inlet body.

[0026] See also Figure 1-4 , an embodiment provided by the utility model:

[0027] A water drainage and gas production wellhead mechanism, comprising:

[0028] A gas inlet body 1 and the ground 2, an annular protective member 3 is arranged on the ground 2 on the outside of the gas inlet body 1, a plurality of shaping anchor bolts 9 are welded to the bottom of the annular protective member 3, a plurality of diagonal braces 6 are hingedly connected to the inner surface of the annular protective member 3, a pad 4 is fixedly installed at one end of the diagonal brace 6, a mounting hole 10 is opened on the top of the pad 4, an inverted cone anchor bolt 5 is inserted through the mounting hole 10, and a door body 12 is arranged on the outer surface of the annular protective member 3.

[0029] A plurality of fixed cylinders 7 are fixedly installed on the outer surfaces of the annular guard 3 and the door body 12, a buffer rod 8 is slidably inserted at one end of the fixed cylinder 7, a spring 13 is fixedly connected between the end of the buffer rod 8 located inside the fixed cylinder 7 and the inner wall of the fixed cylinder 7, a symmetrically distributed limit block 14 is fixedly installed on the outer wall of the buffer rod 8 located at one end inside the fixed cylinder 7, a symmetrically distributed limit groove 16 is opened on the inner wall of the fixed cylinder 7, and the limit groove 16 is slidably connected to the limit block 14, a plurality of anti-collision plates 11 are fixedly installed at one end of the buffer rod 8 located outside the fixed cylinder 7, and the anti-collision plates 11 are equidistantly distributed on the outside of the annular guard 3.

[0030] In one of the embodiments, a sealing anti-slip sleeve 15 is fixedly installed at one end of the fixed tube 7, and the sealing anti-slip sleeve 15 is slidably connected to the buffer rod 8. The sealing anti-slip sleeve 15 has a sealing effect on the sliding connection between the buffer rod 8 and the fixed tube 7, preventing external impurities and dust from entering the interior of the fixed tube 7 and affecting the internal structure of the fixed tube 7.

[0031] In one preferred embodiment, the anti-collision plate 11 is in the shape of an arc plate, which can better adapt to the annular structure of the annular protective member 3 and enable it to effectively absorb and disperse external impact forces. The arc plate design is conducive to the anti-collision plate 11 moving inward after being impacted by falling rocks, and forming an effective linkage mechanism with the buffer rod 8, the fixing tube 7 and the spring 13 to achieve effective buffering and absorption of external impact forces.

[0032] In one of the embodiments, the outer surfaces of the annular protective member 3, the anti-collision plate 11 and the door body 12 are all provided with a wear-resistant coating, which increases the wear resistance of the protective structure and prolongs its service life.

[0033] In one of the preferred embodiments, the door body 12 is hinged to the annular protective member 3 , and a lock is provided between the door body 12 and the annular protective member 3 , so that the staff can enter the interior of the annular protective member 3 through the door body 12 to operate the gas inlet body 1 .

[0034] The working principle of the utility model is as follows: when the annular protective member 3 is in use, it is directly installed on the outside of the gas inlet body 1, and the shaping anchor bolt 9 at the bottom of the annular protective member 3 is directly inserted into the inside of the ground 2 outside the gas inlet body 1, so as to fix the position of the annular protective member 3, and at the same time, the diagonal support 6 is rotated to make the pad 4 at one end of the diagonal support 6 contact the ground 2, and the inverted cone anchor bolt 5 is passed through the inside of the mounting hole 10 and inserted into the inside of the ground 2 through the mounting hole 10 at the top of the pad 4, so as to play a supporting role inside the annular protective member 3, and further improve the stability of the annular protective member 3 on the outside of the gas inlet body 1. Qualitatively, a protective structure is formed on the outside of the gas inlet body 1 through the annular protective part 3. Once falling rocks from the outside hit the annular protective part 3, the impact force caused by the impact will be directly transmitted to the ground 2 through the annular protective part 3. Since there is no connection structure between the annular protective part 3 and the gas inlet body 1, no matter from which direction the annular protective part 3 is hit, the impact force caused by the impact will not have any effect on the gas inlet body 1, thereby achieving effective isolation and dispersion of external impact force, improving the comprehensiveness of the protection effect of the annular protective part 3, and ensuring the stability and safety of the equipment.

[0035] In the process of comprehensively protecting the gas inlet body 1 through the annular protective member 3, when falling rocks from the outside hit the annular protective member 3, they will directly hit the anti-collision plate 11 on the outside of the annular protective member 3. After being hit by the falling rocks, the anti-collision plate 11 will move closer to the annular protective member 3. The movement of the anti-collision plate 11 will drive the buffer rod 8 to slide toward the inside of the fixed tube 7 and squeeze the spring 13. Through the elastic deformation of the spring 13, the impact of the falling rocks can be effectively buffered, reducing the damage of the falling rocks to the anti-slip structure, further improving the protection effect of the protection structure, and facilitating the long-term safe and stable use of the gas inlet body 1.

[0036] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
