Embodiment Construction

[0025] Such as figure 1 As shown, the present invention includes: the liquid inlet pipe section 1, the gradual expansion pipe section 2, the swirl flow generation pipe section 3 and the gradual water removal pipe section 5 connected in sequence, because the inner diameter of the swirl flow pipeline of the swirl flow generation pipe section 3 is larger than the liquid inlet pipe section The inner diameter of the pipeline of 1, therefore, the expanding pipe section 2 is set between the liquid inlet pipe section 1 and the swirl flow generation pipe section 3, and a flow meter 14 is installed on the liquid inlet pipe of the liquid inlet pipe section 1.

[0026] Such as Figure 2~3 As shown, the swirl generation pipe section 3 further includes 4 deflectors 31, 32, 33, 34 that can be fixedly and obliquely installed in the swirl pipe 35, and the deflectors 31, 32, 33, 34 are along Evenly distributed in the circumferential direction, and stacked in sequence in the axial direction of ...

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...
