Abstract

The invention is applicable to the technical field of petrochemical engineering, and provides a gas-liquid separator for an oil field. The separator comprises a shell, and further comprises: a separation assembly, wherein the separation assembly comprises a spiral pipe, the spiral pipe is mounted in the shell and can rotate relative to the shell, a liquid passing hole is formed in the spiral pipe, and the spiral pipe is used for performing gas-liquid centrifugal separation on a gas-liquid mixture; a multi-fold closed soft sleeve movably mounted in the shell and sleeving the periphery of the spiral pipe, wherein a baffling separation cavity is formed between the spiral pipe and the multi-fold closed soft sleeve; and an extrusion backflow assembly used for extruding the multi-fold closed soft sleeve so as to realize extrusion backflow of liquid obtained after gas-liquid mixture separation and make then the gas-liquid mixture subjected to at least two times of separation action. The gas-liquid separator for the oil field can be used for carrying out extrusion circulation type centrifugal separation and baffling separation on the gas-liquid mixture to realize sufficient separation. Meanwhile, separation products can be effectively absorbed, separation is intelligent, and use is convenient.

Description

technical field [0001] The invention belongs to the related technical field of petrochemical industry, and in particular relates to a gas-liquid separator for oil field. Background technique [0002] In the process of oil extraction in oil fields, the recovery of crude oil is often enhanced by gas injection, CO 2 [0003] Oil flooding technology has many advantages. As an effective oil displacement agent, it has a good oil displacement effect. The reason is that CO is dissolved in crude oil. 2 When , the properties of crude oil will change, which will greatly improve the properties of oil reservoirs and increase the recovery of crude oil. [0004] But using CO 2 In oil flooding, the produced product contains a large amount of gas components, which belongs to foaming crude oil, so it is necessary to separate gas and liquid from the produced product. [0005] In the prior art, when the gas-liquid separation is carried out on the produced material, gravity, centrifugal sepa...
