Spiral three-phase media separator

Abstract

A spiral three-phase medium separator. The main purpose is to provide a device for oilfield production that can simultaneously degas and remove sand from the produced fluid, reduce the weight of the separation equipment, and improve the economic benefits of oilfield production. It is characterized in that: a first spiral flow channel is fixed in the first straight pipe section, which runs through the overflow pipe, and there are several first microholes in the lower 1 / 3 of the overflow pipe; there is a guide body in the first straight pipe section, and the guide The trumpet undercut of the fluid is fixed in the center of the first spiral flow channel, and the outlet pipe and the overflow pipe have the same central axis; there is a second spiral flow channel and a discharge pipe in the second straight pipe section; There are several second micropores through the pipe body in the middle section; there is a filter cone in the outer cone section, and a third spiral flow channel is built in the filter cone, and there are several third micropores in the lower 1 / 3 of the filter cone. The hole is perpendicular to the wall of the filter cone; the bottom end of the filter cone is connected with the head end of the drain pipe.

Description

technical field [0001] The invention relates to a multi-phase medium separation and treatment device applied in the fields of petroleum, chemical industry, marine engineering, water treatment and environmental protection. Background technique [0002] With the continuous deepening of the development of many oilfields in my country, the sand content of the produced fluid and the amount of associated gas are increasing year by year. A large amount of sand and gas in the produced fluid will cause great damage to the ground gathering and transportation equipment, and degassing and desanding are indispensable. At present, the sand removal equipment used in oil fields mainly includes gravity sedimentation, filter sand removal, centrifugal sand removal and cyclone sand removal. Among them, gravity settling (tank) belongs to the gravity separation method, which uses density difference for separation. The disadvantage is that it occupies a large area, which is suitable for the land...

Problems solved by technology

Absorption is often used in the treatment and recovery of gaseous pollutants; the adsorption of activated carbon depends on its solubility, surface free energy, polarity, size and unsaturation of adsorbate molecules, concentration of adjuncts, etc.; membrane separation is driven by pressure. Separation is carried out by means of the adsorption capacity of each component in the gas on the surface of the polymer membrane and the difference in dissolution-diffusion in the membrane, that is, the difference in permeation rate, the equipment cost is high, and the requirements for the medium condition are relatively strict.

At present, the produced fluids of most oilfields in my country contain a large amount of impurities such as associated gas and mud and sand. These impurities will not only cause pressure instability and increase the difficulty of transportation, but also cause corrosion and blockage of equipment, and there are many potential safety hazards. Oil field production poses great harm
