Description

Technical Field

[0001] The present application relates to the field of oil and natural gas technology, and in particular to a wellhead water removal device for a tight gas well. Background Art

[0002] As we all know, the Ordos Basin is rich in tight natural gas resources, but it has tight reservoirs, low pressure, low porosity, low permeability, and low production characteristics. Therefore, after a period of production in tight gas wells, the production capacity drops rapidly to the point where the gas wells cannot be drained normally, affecting gas well production. When conventional drainage and gas production processes, such as foam-assisted drainage, plunger gas lift, and velocity tube drainage, are ineffective, it is necessary to use a rod pump drainage and gas production process to drain and improve drainage efficiency.

[0003] At present, in the relevant technology, after searching, the utility model with patent publication number CN211819309U discloses a tight gas well rod pump drainage and gas production wellhead device, including a casing head, a reducer flange, a conversion flange, a lifting short joint, a KQ65 / 21 standard wellhead, a tee and a valve, a sucker rod blowout preventer, a packing box, and a bare rod.

[0004] Regarding the above-mentioned related technologies, although they can play a role in draining water and recovering gas from tight gas wells when used, the applicant has found that since tight gas wells are generally located in slope areas and piedmont structural zones, the exposed gas wellheads and devices are easily hit by falling rocks, which causes damage to the gas wellheads and devices, reduces the service life of the devices, and is insufficient in practicality.

[0005] Therefore, we propose a wellhead water removal device for tight gas wells. Utility Model Content

[0035] When in use, the dense gas wellhead water removal device can be fixedly installed in the use position by setting an installation component. After the wellhead water removal device body 1 is put into use, the multiple baffles 7 can be slid and clamped in the applicable position through the mutual coordination of its fixing ring 4, connecting block 6, and connecting seat 8, so that the multiple baffles 7 form an enclosure. Then, by setting a positioning component, the baffles 7 can be fixed and limited under the action of the positioning component, so that the enclosure formed by the multiple baffles 7 can be used to protect the wellhead water removal device body 1.

[0036] exist Figure 1-3 Middle: The mounting assembly includes four mounting seats 9, which are correspondingly arranged on the outer wall of the connecting sleeve 2. A mounting hole is opened in the mounting seat 9, and a mounting ring 10 is provided in the mounting hole. A butterfly screw 11 is connected to the inner thread of the mounting seat 9.

[0037] The dense gas well wellhead water removal device, through the setting of this structure, after the connecting sleeve 2 is sleeved on the dense gas well, its mounting seat 9 will contact the ground, and then the butterfly screw 11 in the mounting ring 10 can be rotated to make the butterfly screw 11 rotate into the ground, thereby achieving the purpose of fixing and limiting the connecting sleeve 2.

[0038] exist Figure 1-4 Middle: The positioning assembly includes a positioning seat 12, which is fixedly connected to one end of the baffle 7. Three positioning holes are opened in the positioning seat 12, and a restraining sleeve 13 is fixedly installed in the positioning hole. A positioning pile 14 is vertically slidably connected in the restraining sleeve 13.

[0039] The dense gas wellhead water removal device, through the arrangement of this structure, can, after placing multiple baffles 7 in applicable positions, press downward on the positioning piles 14. With the cooperation of the positioning piles 14 and the constraint sleeves 13, the positioning piles 14 are embedded into the soil, thereby achieving the purpose of fixing and limiting the baffles 7 and preventing them from tipping over during use or when impacted.

One end of each of the four baffles 7 is fixedly connected to a composite rubber pad 16 that effectively reduces the impact force brought by gravel. One end of each of the baffles 7 is fixedly connected to a strip handle 17 that facilitates the user to pick up and carry the baffle 7. The external fixed sleeve of the strip handle 17 is provided with an anti-slip rubber sleeve 18 that increases its external friction.

[0041] In this embodiment, the main body 1 of the wellhead water removal device is a well-known equipment purchased directly from the market by technical personnel in this field. It can be customized or selected according to actual needs. Here we only use it and do not make any structural and functional improvements to it. We will not go into details here. The main body 1 of the wellhead water removal device is provided with a control switch that matches it. The installation position of the control switch is selected according to actual use requirements to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0042] The implementation principle of a dense gas wellhead water removal device in an embodiment of the present application is as follows: first, the user can set the connecting sleeve 2 to the wellhead of the dense gas well, and then fix the connecting sleeve 2 and the wellhead water removal device body 1 to the use position through the mutual cooperation of the mounting seat 9, the mounting ring 10, and the butterfly screw 11. After the wellhead water removal device body 1 is put into use, the multiple baffles 7 can be slid and clamped in the applicable position through the mutual cooperation of its fixing ring 4, the connecting block 6, and the connecting seat 8, so that the multiple baffles 7 form an enclosure, and then the multiple baffles 7 are fixed and limited to the use position through the mutual cooperation of the positioning seat 12, the positioning ring and the positioning pile 14, so that the enclosure formed by the multiple baffles 7 can play a role in protecting the wellhead water removal device body 1.
