Thermoelectric composite crude oil processor

Abstract

The invention relates to a thermoelectric composite crude oil processor, which is applied to the dehydration processing of produced fluid of low permeability oil fields with small fault blocks, remote oil wells, polymer oil extraction and marine oil development. The invention comprises a gas preseparator, an oil-water preseparating chamber, a heating furnace chamber, a heating chamber, a thermo-chemical settling chamber and an electric dehydration chamber, wherein, the gas preseparator is used for carrying out oil-gas separation on the produced fluid; the oil-water preseparating chamber is used for carrying out the first oil-water separation on the produced fluid; the heating chamber is used for heating the produced fluid; the thermo-chemical settling chamber is used for carrying out the second oil-water separation on the produced fluid; and the electric dehydration chamber is used for carrying out the third oil-water separation on the produced fluid. The invention comprehensively utilizes technologies of supergravity dehydration, thermo-chemical settling and electric dehydration to carry out oil-water separation effectively on the produced fluid; and the invention also has the advantages of compact equipment structure, no easily-damaged parts, simple operation and maintenance, and low investment and maintenance cost.

Description

technical field [0001] The invention relates to a crude oil processor, in particular to a thermoelectric composite crude oil processor applied to low-permeability small fault block oil fields, remote oil wells, polymer flooding produced fluid processing stations and offshore oil platforms, and belongs to the technical field of oil exploitation. Background technique [0002] At present, the water content of produced fluids in low-permeability small fault block oilfields and remote oil wells continues to rise, and oil-pulling has gradually evolved into water-pulling. The produced fluid has high water content and consumes a lot of thermal energy. In addition to the instability of the fluid coming from the wellhead, it is easy to cause electric field breakdown. However, the crude oil processors at this stage basically use thermochemical sedimentation dehydration in the first stage and electrochemical dehydration treatment in the second stage. There has been a technological resur...
