Novel anti-settling sand stuck pump device

Abstract

The invention refers to an anti-sand device used for an oilfield well. Especially, the invention relates to a novel anti-settling sand stuck pump device, wherein the technical scheme of the novel anti-settling sand stuck pump device is that: the device consists of a taper body, a taper base, a valve body, a fixing base, a valve ball and a joint; one end of the fixing base is connected with the joint, and the other end of the fixing base is connected with the taper base by screw thread; the valve body is fixed at the inner part of the taper base, the valve ball is arranged in the valve body; the valve body is vertically provided with a liquid through hole. The novel anti-settling sand stuck pump device has the following beneficial effects: the novel anti-settling sand stuck pump device is reasonable in structural design and good in anti-sand effect; the problem that the grit enters the pump along with the output liquid is effectively solved; the stuck pump is prevented; the device can be freely lifted up and down along with a sucker rod; so that the other work cannot be affected, and any other additional work load cannot be taken to the work.

Description

technical field [0001] The invention relates to a sand control device for oil field wells, in particular to a novel pump device for preventing sand settling stuck. Background technique [0002] In the process of oil field production, because many oil wells produce sand, that is, the crude oil produced by the oil pump contains sand to varying degrees, and the sand and gravel enter the pump with the output fluid. The sinking increases the wear and tear of the pump. What is more serious is that when the pumping is stopped due to various reasons, the sinking of the sand will cause the pump to be stuck, resulting in an accident of sand stuck in the pump or the valve is not closed tightly, resulting in pump leakage. For the problem of oil well pump wear, relevant technicians have designed various sand control pumps. Although these solutions have solved some problems to a certain extent, the problem of pump wear caused by the sinking of sand contained in crude oil has not been comp...

[0002] In the process of oil field production, because many oil wells produce sand, that is, the crude oil produced by the oil pump contains sand to varying degrees, and the sand and gravel enter the pump with the output fluid. The sinking increases the wear and tear of the pump. What is more serious is that when the pumping is stopped due to various reasons, the sinking of the sand will cause the pump to be stuck, resulting in an accident of sand stuck in the pump or the valve is not closed tightly, resulting in pump leakage. In order to solve the For the problem of oil well pump wear, relevant technicians have designed a variety of sand control pumps. Although these solutions have solved some problems to a certain extent, the problem of pump wear caused by the sinking of sand contained in crude oil has not been completely solved. , especially the problem of the pump being stuck in the sand setting is even more difficult to solve, which affects the production of the oil field
