Abstract
The invention relates to an oil extraction and water injection synchronous conduction control system in the same oil well. The oil extraction and water injection synchronous conduction control system comprises a motor, a pump, a protector, a downhole sensor, a power cable and a liquid guide pipe, wherein one end of the motor is connected with the power cable, the other end of the motor is connected with the protector, and the other end of the protector is connected with a suction inlet. The motor, the protector and the suction inlet are all arranged inside the liquid guide pipe, the suction port is connected with the pump which is connected with the downhole sensor, and the downhole sensor is connected with a point of the motor through a signal transmission line. According to the oil extraction and water injection synchronous conduction control system, the structure is simple, connection is convenient, and due to synchronous conduction of oil extraction and water injection in the same oil well, energy conservation and environment protection are achieved, technological processes are simplified, production cost is reduced, and production efficiency is improved.
Description
Technical field
The invention belongs to oil field equipment water-oil separating control system technical field, particularly control system is carried out in oil recovery and water filling synchronously in a kind of same oil well.
Background technology
With the exploitation of landing field and offshore oilfield, the height of extraction liquid contains water problems and displays gradually, and height contains water problems and improved cost for oil production, has limited production scale, and environment has been caused many negative effects.At present, the main oil recovery water discharge method in China oil field all is that crude oil is lifted to ground, and the technological process by ground is water-oil separating, again by the ground water injection equipment with produced-water reinjection to the down-hole water layer.These methods make ground installation many, and manufacturing process is loaded down with trivial details, and the cost of production height not only pollutes ground and wastes energy.
Summary of the invention
