North China Oil and Gas Screw Pump Successfully Tests the New Technology of Production and Injection to Improve Efficiency in the Same Well

SINOPEC News Network News As of July 24, the North China Oil and Gas Branch carried out the first high-yield screw pump in the Dongsheng Gas Field J58P40H well for the first time to test a new technology for improving the efficiency of production and injection of high-yield liquid wells, and achieved good results in stabilizing production and reducing consumption
.

J58P40H is a typical high-yield liquid gas well in Jin58 well area of ​​Dongsheng Gas Field.
It failed to spout production after pumping more than 100 times during the gas test stage.
The technicians passed geological evaluation and analysis, and used electric submersible pumps to assist in the production and injection process of the same well.

.

For this reason, the second joint gas production plant of the Academy of Engineering carried out for the first time in the Dongsheng Gas Field J58P40H well J58P40H, a new technology test of the same well production and injection efficiency improvement of the screw pump, in order to achieve the goal of continuous stable production and increased production of high-yield liquid gas wells
.

The production and injection process of the screw pump in the same well is through the integration of gas-liquid separation of the guide cover, the conversion of bridge devices, and the discharge technology of the screw pump.
Gas-liquid separation, liquid reinjection in wells, and separated gas are directly collected and transported into the station
.

At present, the implementation of the results of the screw pump production and injection process in the same well has laid a solid foundation for the economic and effective production of the branch's high-yield liquid gas wells
