Timing automatic ball-throwing apparatus and method

Abstract

The invention belongs to oil production and oil collecting equipment of an oil field, and relates to a ball injector in production and establishing engineering of the oil field, in particular to a timing automatic ball injector and a method thereof. The ball injector is characterized by comprising a ball-packing cylinder (1), a control valve (3) and a control unit (9); one end of the ball-packing cylinder (1) is an inlet for paraffin removal balls (2), and the other end thereof is an outlet for the paraffin removal balls (2); the outlet for the paraffin removal balls (2) is connected with a port of the control valve (3) of a connecting pipeline (11); the control valve (3) is a ball valve which is connected between a crude oil input pipeline (5) and a crude oil output pipeline (10); a ball valve core (4) is turned by 90 degrees through an electric head (8) of the control ball valve; the paraffin removal balls (2) of the ball-packing cylinder (1) carry out paraffin removal along the direction of the crude oil output pipeline (10); the ball valve core (4) is turned to be reset through the electric head (8) of the control ball valve; and the paraffin removal balls (2) of the ball-packing cylinder (1) are blocked. The ball injector can be used for reducing the cost of oil production and reducing the labor intensity of employees.

Description

technical field [0001] The invention belongs to oil extraction and oil collection equipment in an oil field, and relates to a ball throwing device in an oil field production and construction project, in particular to a timing automatic ball throwing device and method. Background technique [0002] At present, oil production and oil collection methods in various oil fields are transported from oil wells to oil gathering stations or centralized processing stations using single well pipelines. Due to the large temperature difference between the ground and the underground, after the crude oil is pumped out of the ground, a large amount of wax will be precipitated and adhered to the inner wall of the oil pipeline. If it is not cleaned for a few days, the oil pipeline will be blocked. Pipelines and long-distance pipelines need to throw balls to remove wax, so oil production workers need to go to the well site to throw balls into the oil pipeline every day to remove wax. There are ...

Problems solved by technology

Due to the large temperature difference between the ground and the underground, after the crude oil is pumped out of the ground, a large amount of wax will be precipitated and adhered to the inner wall of the oil pipeline. If it is not cleaned for a few days, the oil pipeline will be blocked. Pipelines and long-distance pipelines need to throw balls to remove wax, so oil production workers need to go to the well site to throw balls into the oil pipeline every day to remove wax. There are about tens of thousands of oil wells in a large oil field, and each well is manually thrown every day, requiring a large number of personnel and vehicles Cooperate, over the past few decades, the pitching device has undergone many improvements. Although it is a mature technology, it has not gotten rid of the cumbersome manual operation, that is, every time the ball is thrown, the two valves at the front and rear of the pitching device are first closed, and then the ball is released. Then put the wax removal ball into the pipeline; open the two valves before and after the ball throwing device, and push the wax removal ball into the oil pipeline. Such a cumbersome operation is difficult to achieve automatic control, so there is an urgent need for a timing automatic ball throwing system. device to reduce the cost of oil production and reduce the labor intensity of employees
