Technical Field
The utility model relates to a supercharging equipment technical field, concretely relates to hydraulic jet pump well head supercharging device.
Background
When natural gas, shale gas or coal bed gas are extracted from the underground, the influence of wellhead backpressure on the capacity improvement is large, the pressure of the natural gas, the shale gas or the coal bed gas is reduced along with the continuous extraction, and the yield is reduced. When the pressure is lower than a certain level, natural gas, shale gas or coal bed gas needs to be pressurized at a wellhead, so that the produced natural gas, shale gas or coal bed gas has improved yield or has enough power to be transported to a gathering and transportation station.
At present, no ideal natural gas supercharging device can perform pressure increase production on natural gas at a wellhead. The main difficulty is that the natural gas contains water and condensate oil and dust, and the existence of the liquid and the dust makes the pressurized operation of the natural gas difficult. At present, no matter a screw compressor or a reciprocating compressor is adopted for pressurizing natural gas, shale gas or coal bed gas, the natural gas, the shale gas or the coal bed gas can not normally work under the condition of water, the running time of equipment can be greatly reduced due to the existence of dust, and the failure rate is improved. Compressed natural gas also has certain potential safety hazards. Therefore, the design of a pipeline type hydraulic jet pump wellhead supercharging device installed on a wellhead is urgently needed to solve the problem that the existing supercharging equipment cannot effectively supercharge gas-liquid mixed liquid.
