Problems solved by technology

[0008] The gas-liquid-solid three-phase separator has a high degree of integration, but in the process of use, the solid phase (sand particles) will be discharged together with the liquid through the liquid collection hole on the liquid collection section, resulting in poor solid-liquid separation effect; At the same time, the gas-liquid-solid (such as pressure, flow) produced by the oil and gas field fluctuates greatly, and the size of the liquid collecting hole on the liquid collecting section is fixed, so it will not be able to effectively collect liquid to achieve solid-liquid separation

Abstract

The invention discloses a gas-liquid-solid three-phase separator, which is used for solving the problems that the existing separator is big in size and poor in separation effect. The gas-liquid-solid three-phase separator comprises a feeding port, a gas discharging end and a solid-liquid discharging end, wherein the feeding port, the gas discharging end and the solid-liquid discharging end are formed on a cylinder body; the feeding port is tangentially formed in the cylinder body; the gas discharging end comprises a gas ascending pipe and a gas outlet which are mutually communicated; a silk screen mist catcher is arranged between the gas ascending pipe and the gas outlet; a spiral guide plate is arranged on the outer wall of the gas ascending pipe and is communicated with the feeding port; the solid-liquid discharging end comprises a liquid outlet, a sand discharging port and a liquid discharging valve assembly; the sand discharging port is provided with a sand washing mouth for preventing the sand discharging port from being blocked; the liquid discharging valve assembly comprises a floater; the lower end of the floater is connected with a valve core; the valve core is matched with a liquid outlet. The gas-liquid-solid three-phase separator has the characteristics of simple structure and good separation effect.

Description

technical field [0001] The invention belongs to the technical field of oil and gas field exploitation, and specifically relates to a three-phase separator for separating gas (mainly natural gas), liquid (petroleum, gas field water) and solid (sand and other solid impurities) extracted from oil and gas fields. Background technique [0002] In oil and gas extraction, oil and gas extracted from oil and gas field wells are generally in the form of gas, liquid phase fluid and contain a small amount of solid particles (sand). The general single well production process is to firstly separate and remove impurities such as sand particles, then separate gas and liquid, and measure and test them separately. Then the gas and liquid are mixed and transported to the gathering station or treatment plant for further separation and purification. [0003] At present, there are many devices for gas, liquid and solid three-phase separation. For example, the invention patent with application nu...
