Problems solved by technology

[0002] After the oil field is exploited in the middle and late stage, the way of water injection into the formation or polymer flooding is generally used to ensure the crude oil production. The water injection wells are generally divided into multiple layers, and the precise control of the water injection in each layer is the key to ensure the output. In the process of water injection in the oil field, intelligent water distributors are needed. The current water distributors cannot accurately grasp the amount of water injected during the water injection process, which leads to a small oil output from the oil well. At the same time, the pressure values ​​of different layers are different in the injection The pressure cannot be effectively controlled during the process, which may easily lead to the problem of backflow of water

Abstract

The invention relates to the technical field of water distributors, and discloses a bridge type concentric constant-pressure intelligent water distributor used for a water injection well. The distributor comprises an upper joint pipe, a water distributor body is fixedly mounted on the bottom of the upper joint pipe, a lower joint pipe is fixedly mounted on the bottom of the water distributor body,the bottom of an inner cavity of the upper joint pipe is fixedly sleeved with a seal ring, a hollow groove is formed in one side of the water distributor body, a sensor is fixedly mounted in an innercavity of the hollow groove, the top of the sensor is fixedly connected with a cable, one end of the cable penetrates to the top of the water distributor body and extends to the ground, and one end of the cable is fixedly connected with a fixed plate. According to the bridge type concentric constant-pressure intelligent water distributor used for the water injection well, through cooperation of awater injection pressure device, a micro hydraulic pump and a seal plug, water can be better injected into different layers conveniently, the problem that in the water injection process, the injectedwater amount cannot be accurately mastered, and the oilfield exploitation oil pump capacity is small is solved, and the oilfield exploitation oil pump capacity is improved.
