Axial type inlet oil-water cyclone separator

Abstract

The invention discloses an axial type inlet oil-water cyclone separator comprising a liquid inlet pipe section, a cyclone generation pipe section and a water outlet pipe section, which are sequentially connected, wherein the cyclone generation pipe section further comprises a cyclone pipeline and more than two diversion sheets which can be fixed and obliquely mounted in the cyclone pipeline, and the diversion sheets are uniformly distributed along the circumferential direction of the cyclone pipeline and sequentially superposed in the axial direction of the cyclone pipeline; when oil-water mixed flow liquid flows through the diversion sheets, a centrosymmetric cyclone field is formed and the centrifugal separation of oil and water in the cyclone field is further realized. The axial type inlet oil-water cyclone separator is an oil-water separation device utilizing the cyclone principle, the inner diameters of the liquid inlet pipe section and the water outlet pipe section are the same, only one section on a liquid collecting pipeline which needs the treatment needs to be cut off for mounting the separator, the pipe flow direction is not changed and the applicability is good; compared with a traditional gravity settling separation device, the treatment efficiency is obviously improved and the occupied space is smaller.

Description

technical field [0001] The invention relates to a system for separating oil-water two-phase mixed liquid, in particular to an oil-water separation system applied to high water-cut oil wells and future deep-water oilfield underwater treatment systems. Background technique [0002] With the continuous development of oil fields, most of my country's oil fields have entered the medium and high water-cut development period, and the water content in the oil well production fluid has generally reached more than 90%. Due to the continuous increase of water content, the lifting cost of the produced fluid increases, and the production cost continues to increase. When the cost of pumping the mixed fluid is higher than the income brought by the separated oil, the oil well will be on the verge of the limit of economic production and be shut down. Forced to stop production. Therefore, the use of oil-water pre-separation equipment in oil wells is of great significance to improve the recov...

Problems solved by technology

Both of these two are based on the centrifugal principle for oil-water separation. What they have in common is that they have moving parts and maintenance is more troublesome.
