Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing.

[0034] First of all, with reference to the accompanying drawings, an overall description will be made of a novel downhole gas-liquid cyclone separation device according to the present invention: the appearance of the new downhole gas-liquid cyclone separation device is a cylindrical casing structure such as figure 1 As shown, there is an incoming gas inlet 1, a primary liquid phase outlet 2, a multi-stage liquid phase outlet 3, and a gas phase outlet 4. The mixed phase enters the gas inlet 1 of the cyclone from the gas pipeline and enters the inside of the separation device. After multi-stage separation, the water phase is discharged from the device through the first-level liquid phase outlet 2 or the second-level liquid phase outlet 3, and the gas phase is separated from the gas phase outlet. 4 discharge.

Abstract

The invention discloses an underground gas-liquid hydrocyclone separation device. The hydrocyclone separation device mainly solves the problem that liquid drops are entrained in a gas phase separatedby an existing hydrocyclone separation device. The gas-liquid hydrocyclone separation device is characterized in that the separation device is of a nested pipe type structure, and the two sides of a gas supply sleeve are sealed through gaskets; the gas supply sleeve internally comprises a cylindrical shell and a tangential inlet shell, and the cylindrical shell is used for protecting an internal structure and reducing abrasion and corrosion of the internal structure; the internal structure comprises a tangential inlet disc, an upper hydrocyclone cavity, an internal hydrocyclone device and a gas-liquid separation cavity; after entering a gas supply pipeline, the mixed phase enters the internal hydrocyclone device along a tangential inlet for primary separation, and a gas phase separation cavity is nested in the internal hydrocyclone device to reduce the liquid content of the separated gas phase; and the upper hydrocyclone cavity is formed in the upper portion of the internal hydrocyclone device and is used for carrying out multi-stage separation on the separated gas phase.

Description

technical field [0001] The invention relates to a cyclone separation device applied in the fields of petroleum, chemical industry, environmental protection and the like. Background technique [0002] With the deep exploitation of oil, the water content in the well increases year by year, and it is necessary to separate the water phase and the gas phase in the well. In addition, the water phase, as an impurity, will be carried by the gas phase when the gas phase flow rate is large, thus affecting the volume fraction of the separated gas phase. At present, although the existing gas anchor device can be applied to separate the water phase and the gas phase in the small space downhole, the separation effect is not good, and it is often damaged and difficult to repair. Contents of the invention [0003] In order to solve the existing technical problems mentioned in the background technology, the present invention proposes a downhole gas-liquid cyclone separation device. This k...
