An adjustable sand-setting gas anchor for pumping wells

Abstract

The invention discloses an adjustable sanding gas anchor for pumping wells. Its technical proposal is: it includes a lower connecting pipe, a middle connecting pipe, an upper connecting pipe, a collection structure and an agitating structure. A sliding rod is inserted into the inner wall of the left end of the lower connecting pipe. The left end of the slide bar is fixedly installed with a moving seat, the moving seat is sleeved on the left end of the lower connecting pipe, the inner wall of the right end of the lower connecting pipe is fixedly installed with the collection structure, the collecting structure includes a support plate, and the support plate is fixedly installed on the Describe the inner wall of the connecting pipe, the filter screen is fixedly installed on the left end of the support plate, the positioning seat 2 is fixedly installed on the inside of the filter screen, the splitter leaf is fixedly installed on the inside of the positioning seat 2, and the gas collection chamber is fixedly installed on the left end of the filter screen, the present invention The beneficial effect is that the sand-setting gas anchor of the pumping well is set to be adjustable, and the stirring device is arranged, so that the sand-setting gas anchor can be adjusted, the gas collection rate is fast, and it is not easy to be blocked.

Description

An adjustable sand settling gas anchor for oil wells technical field [0001] The present invention relates to a sand settling gas anchor used in petroleum development, in particular to a kind of adjustable sand settling gas anchor for pumping wells. Background technique Oil well is exploiting oil, according to the hole drilled by the well layout system of oilfield development planning, oil rises to well from bottom of well. The channel of the mouth, the oil well is the hole drilled by the drilling method. After the oil well reaches the oil layer, the oil layer casing is put into the oil layer, and the casing is drilled in the casing. Oil well cement is injected into the annular space between the well wall to maintain the well wall and seal the oil, gas and water layers, and then according to the requirements of oilfield development The oil layer is shot with a perforating gun to form a channel. For the oil pump, the gas entering it will reduce the pump efficiency and af...
