Abstract

The invention relates to a rotational flow paraffin removal device. A reversing flow guider is further arranged in the inlet end of a rotational flow shell, a water blending pipe is arranged at the center of the reversing flow guider, the part, located at the inlet end of the rotational flow shell, of the water blending pipe extends outwards in the circumferential direction to form a shoulder, and a plurality of small holes are formed in the shoulder in the transverse direction; a water blending inlet is formed in the side wall of the rotational flow shell, a through hole is further formed in the shoulder of the reversing flow guider in the longitudinal direction, one end of the through hole is communicated with the water blending inlet, and the other end of the through hole is communicated with the water blending pipe of the reversing flow guider; a water blending helix efficient hydrocyclone is installed in the water blending pipe, an inlet helix efficient hydrocyclone is installed in the space between the water blending pipe and the rotational flow shell, multiple circular rotational flow channels are formed in the outer wall of the water blending helix efficient hydrocyclone, and multiple circular rotational flow channels are formed in the outer wall of the inlet helix efficient hydrocyclone. The rotational flow paraffin removal device solves the problems that in the past, the cooling speed of blended cold water is low, water blending push rotating force is small, rotation intensity of collected liquid from a wellhead is small, and paraffin removal cost is excessively high.

Description

technical field [0001] The invention belongs to the field of oilfield devices, in particular to a swirl wax removal device. Background technique [0002] For oilfields with high wax content post-development oilfields, where the comprehensive water cut of oil production exceeds 90%, how to prevent wax deposition in gathering and transportation pipelines is a difficult problem. The liquid produced by the oil well contains crude oil, water and natural gas, and the crude oil contains paraffin. The temperature of the collection and transportation fluid discharged from the wellhead is about 40°C. During the transportation process through the collection and transportation pipeline, due to heat dissipation, the temperature of the collection and transportation fluid gradually increases from 40 ℃ drops to about 30 ℃. During this process, the paraffin is in contact with the tube wall and continuously condenses into solid paraffin on the inner wall of the tube. This process is called th...
