The boiler steam vacuum system was replaced by hydraulic jet vacuum system.

On the basis of analyzing the influence factors of hydraulic jet pump production effect in detail in Gudao Oilfield, a systematic software for optimizing the hydraulic jet pump parameters is developed by using dynamic and static data from the hydraulic jet pumping wells in combination with the pump performance curves.

Study of fracturing mechanism and test of hydraulic jetting with coiled tubing;

Hydraulic fracturing combined with coiled tubing has become a highly efficient measure for EOR,which complete snubbing service,hydraulic jetting perforation,and segregated completion as a whole.

In order to simplify operation process and reduce cost,a combined technology of hydraulic jetting oriented perforating and fracturing has been applied in many horizontal wells in Changqing Oilfield.

Influential factors of blending ratio in heavy oil lifting with hydraulic jet pump

Application of hydraulic jet pump in production of particular reservoirs

The electric submersible pump driven jet pumping system is the optimized combination of electric submersible pump and hydraulic jet pump, and is made up of electric submersible pump set, jet pump set, control manifold and metering instruments, downhole testing device and auxiliary accessories.
