Abstract
The utility model discloses a filtering device for the tail pipe of a deep-well pump, which solves the technical problems that the deep-well pump is stuck by the entrance of sundries such as oil reservoir superfine sand, solid phase mud, scale chip, scrap iron, rubber and the like to the pump. The pump has the advantages of simple structure and convenient use, thereby can be installed on the tail pipe of a deep-well pump and realizing compound sand and shale removing and blocking. The filtering device comprises a pipe body, an upper joint and a lower joint which are arranged on the pipe body, a central tube is fixedly arranged in the pipe body, a plurality of pinholes are arranged on the central pipe, and a wire wrapped filtering screen is arranged outside of the central pipe.
Description
Technical field
The utility model relates to a kind of deep well pump tail pipe filter.
Background technology
At present, sand control all is the method for taking oil reservoir borehole wall sand control, and this anti-sand method can be protected oil reservoir, and the control sand production in oil prevents that sand from burying oil reservoir.But have solid sundries to enter in the pump along tail pipe in shale powder fine sand in the oil reservoir and the pit shaft, cause the pump card and the well of lying not only influences crude output, and operating cost increases with liquid in the well.
Summary of the invention
The purpose of this utility model is exactly in order to solve the technical problem that foreign material such as entering oil reservoir powder fine sand, solid phase mud, dirty sheet, iron filings, rubber in the pump cause deep well pump pump card, provide a kind of have simple in structure, easy to use, can be installed on the deep well pump tail pipe, and play compound remove sand block, shale etc. the deep well pump tail pipe filter of advantage.
For achieving the above object, the utility model adopts following technical scheme:
A kind of deep well pump tail pipe filter, it comprises body, is provided with top connection and lower contact on body, installs central tube in body inside, central tube is provided with an aperture of doing more, is provided with the wrapping wire filter screen outside central tube.
Be respectively equipped with screw thread in described top connection and the lower contact.
Deep well pump tail pipe filter of the present utility model mainly is made up of five parts such as top connection, body, wrapping wire filter screen, central tube, lower contacts, and helicitic texture is adopted in last lower contact, and the pipe inner part adopts and is welded to connect.It is installed on the deep well pump tail pipe, and its lower contact connects the oil pipe of 2 band plugs, as sedimentation pipe; Its top connection is connected under the pump on the tail pipe.
The beneficial effects of the utility model are: simple in structure, easy to use, can play the compound effects such as sand block, shale that remove.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1. top connection, 2. body, 3. lower contact, 4. screw thread, 5. wrapping wire filtration beds, 6. central tube.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, it comprises body 2, is provided with top connection 1 and lower contact 3 on body 2, installs central tube 6 in body 2 inside, and central tube 6 is provided with an aperture of doing more, is provided with wrapping wire filter screen 5 outside central tube 6.Be respectively equipped with screw thread 4 in top connection 1 and the lower contact 3.
