Abstract

The utility model relates to a well head filter of a pumping well, comprising a choke seat on which an oil outlet is arranged. The well head filter of the pumping well is further provided with a filter pipe, a bushing, a plug head and a sealing plug; a thread at the left end of the filter pipe is connected with a thread at the left end of the choke seat; a thread at the left end of the bushing is connected with a thread at the right end of the choke seat; the bushing covers the filter pipe; the right end of the filter pipe is provided with the plug head; the right end of the bushing is provided with the sealing plug; and the filter pipe is provided with a filter hole. Only oil can flow out from the filter hole, nonmetal fragments are left in the filter pipe instead of entering an oil delivery pipeline, thereby having no problem of plugging the oil delivery pipeline; the sealing plug, the plug head and the filter pipe are respectively dismounted for clearing the nonmetal fragments after production for a period of time, the oil well can continue producing without the occurrence of production stop caused by the plugging of the nonmetal fragments, and the well can normally produce for long term; and the well head filter of the pumping well has obvious social benefits.

Description

Pumpingh well well head filter

One, technical field

The utility model is the wellhead assembly that oil field pumping well is used, and is a kind of pumpingh well well head filter.

Two, background technology

Nonmetal parts are arranged in present downhole tool and the oil pipe, as the high density polyethylene (HDPE) inner liner in the liner oil pipe, these nonmetal parts come off in process of production easily, the nonmetal fragment that comes off is drawn out of and flow in the feed-line of ground, and the ground feed-line turns round and deformation section, and nonmetal fragment is trapped in these places easily, cause the ground petroleum pipeline blocked, cause that oil well can not produce, need a large amount of manpower and materials of cost could recover oil well production, cause heavy economic losses.

Three, summary of the invention

The purpose of this utility model provides a kind of pumpingh well well head filter, the nonmetal fragment that flows out can be stopped, and prevents to stop up the ground petroleum pipeline.

The purpose of this utility model has been achieved in that the oil nozzle cover, oil nozzle has put oil outlet, also have screen pipe, sleeve pipe, obstruction head, sealing plug, screen pipe left end screw thread is threaded with oil nozzle cover left end, sleeve pipe left end screw thread is threaded with oil nozzle cover right-hand member, and sleeve pipe covers screen pipe, and the screen pipe right-hand member is installed and stopped up head, the sleeve pipe right-hand member is installed the sealing plug, and filtering holes is arranged on the screen pipe.

The beneficial effects of the utility model are: have only oily stream to flow out from filtering holes, nonmetal fragment remains in screen pipe, can not enter in the petroleum pipeline, does not have the problem of stopping up petroleum pipeline, and oil well is ordinary production for a long time, has remarkable economic efficiency.

Four, description of drawings

Accompanying drawing is a structure installation diagram of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described.

Embodiment of the present utility model by oil nozzle cover 1, screen pipe 2, sleeve pipe 3, stop up 4, sealing plug 5 forms, on the oil nozzle cover 1 oil outlet 6 is arranged, screen pipe 2 left end screw threads overlap 1 left end with oil nozzle and are threaded, sleeve pipe 3 left end screw threads overlap 1 right-hand member with oil nozzle and are threaded, sleeve pipe 3 covers screen pipe 2, screen pipe 2 right-hand members install to stop up 4, and sleeve pipe 3 right-hand members are installed sealing plug 5, and filtering holes 7 is arranged on the screen pipe 2.

Oil nozzle cover 1 is installed on the production tree.The oil stream that carries nonmetal fragment is when oil nozzle cover 1 flows out through screen pipe 2, nonmetal fragment remains in the screen pipe, oil stream flows out in oil outlet 6 flow to the ground petroleum pipeline from filtering holes, through production after a while, respectively dismounting sealing plug 5 and stop up 4, screen pipe 2, nonmetal fragment is removed, and oil well can continue to produce, and nonmetal clogged with fragments can not take place stop production.
