Water source heat pump heat-supply device for oil field well mouth

Abstract

A water-source heat pump heating device used for oil field wellhead includes wellhead medium transmission tube, heat exchange medium output tube for connecting gathering station, water-source heat interchanger connected to water-source heat pump group, pumping submersible pump and recharge water tube which are assembled in well tube of heat collector well. The technical points includes that: the wellhead medium transmission tube and the heat exchange medium output tube connected to the gathering station are respectively connected to heat exchange medium inlet end and outlet end of the medium heater, and high temperature cycle pipeline of the heat pump group is connected to heating pipe in the medium heater, double-channel non-plug impeller comprised by main, vice impellers and automatic control powerful pollution discharge pump of fixed stirrer assembled at terminal end of motor shaft are arranged at bottom of the recharge water level in well tube of the heat collection well, outlet end of the pump is connected to sedimentation pond outside the well tube. The invention has reasonable design, easy operation, and can save primary energy and improve stability and safety of the oil well.

Description

technical field [0001] The invention relates to a heating and temperature-raising device for the mixed medium of crude oil, water and gas collected in oil wells, in particular to an oil field wellhead using water source heat pump heat collection technology and heat exchangers to replace the water jacket furnace to heat the mixed medium collected in oil wells Water source heat pump heating device. It can also be used as a cold and heat source for other temperature adjustment places. Background technique [0002] At present, the mixed medium of crude oil, water, and gas collected at the wellhead of the oil field and its gathering and transportation station (combined station) needs to be heated up to prevent the mixed medium flowing through the wellhead device or the gathering and transportation station from sticking. Or freeze to ensure the smooth flow of oil pipelines. Traditional heating devices generally use coal-fired, oil-fired, gas-fired water jacket furnaces or electr...
