Oil and gas mixed pump

Abstract

The invention discloses an oil-gas mixed transport pump, which includes a pump body and a liquid collecting device. The pump body includes a pump casing and a pump cavity for accommodating a screw in the pump casing. An oil outlet is arranged in the middle section of the pump cavity and runs through the pump body. , the above-mentioned pump casing is also provided with an oil inlet chamber, the two ends of the above-mentioned oil inlet chamber are connected with the two ends of the above-mentioned pump chamber, the above-mentioned oil inlet chamber is provided with an oil inlet that penetrates the above-mentioned pump body, and the above-mentioned liquid collecting device includes a cylindrical collection Liquid tank, input pipe, liquid output device, the bottom of the liquid collection tank is connected to the liquid output device, the pipe wall of the liquid collection tank is provided with an input port, the input pipe extends into the input port to the inside of the liquid collection tank, the input pipe The nozzle of the nozzle is close to the inner wall of the liquid collection tank, and the central axis of the nozzle is inclined downward and is tangent to the inner wall of the liquid collection tank where the nozzle is located. The beneficial effect of the present invention is that, through the gas-liquid separation of natural gas through the device, the liquid natural gas is sent back to the peripheral space of the pump chamber to realize the "gas-in-liquid" state.

Description

technical field [0001] The invention relates to a pump, especially an oil-gas mixed transportation pump. Background technique [0002] As an important equipment for the extraction, collection and transportation of crude oil and natural gas, the oil and gas mixed transportation pump is widely used in the field of petroleum exploitation. It is a pump derived from the development of the petroleum industry in the past ten years. Corresponding research and product development have been invested in foreign countries; domestic theoretical research is almost blank, and corresponding products are not available. Traditional pumps can only transport liquids and cannot work normally when encountering gas in the medium. Therefore, it is very meaningful to design a pump that can realize multi-phase transportation of liquid and gas. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an oil-gas mixed transportation pump. [0004]...
