Abstract

The present invention is applicable to the technical field of petrochemical industry, and provides a gas-liquid separator for oil field, which includes a casing, and also includes: a separation assembly, which includes: a spiral tube, which is installed in the casing and can be rotatably arranged relative to the casing , the spiral tube is provided with a liquid hole, and the spiral tube is used for gas-liquid centrifugal separation of the gas-liquid mixture; the multi-fold closed soft sleeve is movably installed in the shell and sleeved on the periphery of the spiral tube; the spiral tube A baffle and separation cavity is formed between the multi-fold closed soft cover; and a squeeze return component is used to squeeze the multi-fold closed soft cover to realize the squeeze backflow of the liquid obtained after the gas-liquid mixture is separated, and then the gas-liquid The mixture undergoes at least two separations. The gas-liquid separator for oilfields provided by the present invention can carry out extrusion cycle centrifugal separation and baffle separation for the gas-liquid mixture, and the separation is sufficient. At the same time, it can effectively absorb the separated products, and the separation is intelligent. Easy to use.

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...
