Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] see figure 1 , which shows a gas eliminator 100 for gas-liquid separation according to an embodiment of the present invention. The gas eliminator 100 includes a gas-liquid separation column 10, a centrifugal assembly 20 and a gas phase shroud 30, and the centrifugal assembly 20 and the gas phase shroud 30 are all accommodated in the inner chamber of the gas-liquid separation column 10, and the centrifugal assembly 20 and the gas phase The shrouds 30 are spaced apart from each other. Specifically, when in use, the oilfield production fluid is sprayed into the centrifugal assembly 20, and then the centrifugal assembly 20 and the gas phase shroud 30 cooperate with each other to realize the first centrifugal separation and the seco...

Abstract

The invention discloses a getter device used for gas-liquid separation and belongs to the field of oilfield ground facilities. The getter device comprises a gas-liquid separating pipe column, a centrifugal assembly and a gas phase flow guiding cover. The centrifugal assembly and the gas phase flow guiding cover both are contained in an inner cavity of the gas-liquid separating pipe column and arranged in a spaced mode. When the getter device is used, oilfield produced liquid is sprayed into the centrifugal assembly, and then the centrifugal assembly and the gas phase flow guiding cover are matched with each other to achieve first centrifugal separating and second centrifugal separating of the oilfield produced liquid. The getter device used for gas-liquid separation is simple in structure and good in separating effect; rapid and efficient gas-liquid separating can be conducted on the oilfield produced liquid, and full gas-liquid separating can further be conducted on the oilfield produced liquid; the getter device is applied to eliminate associated gas in the oilfield produced liquid; and the getter device can be used in front of various flow meters in a station as well as used by being matched with three phase metering device at the time of gas-liquid separating of the oilfield single well produced liquid.

Description

technical field [0001] The invention relates to the field of oilfield ground facilities, in particular to a gas eliminator for gas-liquid separation. Background technique [0002] In the process of oil well production, due to the generation of associated gas, oil well production often presents a state of three-phase coexistence of oil, gas and water. Therefore, in the measurement of oil well production fluid, due to the associated gas in the production fluid, the measurement of oil well production fluid production is inaccurate, which in turn results in a large measurement error in the surface oil gathering system, resulting in wrong judgments during geological dynamic analysis And affect the formulation of oilfield geological dynamic management measures. [0003] Therefore, before metering, a separator is usually used to separate the gas-liquid of the oil well production liquid, so as to separate the three-phase flow into a single-phase flow, so as to solve the problem of ...
