Abstract

A gas and liquid segregator of oil gas and automatically discharged vortex is used for oil and gas separation of crude oil. The segregator includes a tank body, the bottom of which is provided with a sewage draining exit, and the middle part of the tank body is provided with an inlet. A cyclone and a gas phase introducing opening are arranged inside the tank body. The segregator is characterized in that an automatically discharging device of air phase is fixed at the top of the tank body; the automatically discharging device of air phase is connected with an air phase discharging pipeline, which is connected with a constant pressure flow-control valve of an air phase outlet. The bottom of the tank body is connected with a liquid phase discharging pipeline, which is connected with an automatically discharging device of liquid phase, and the automatically discharging device of liquid phase is connected with a constant pressure flow-control valve of a fluid phase outlet. The functions of improving the gas and liquid separation effect as well as automatically discharging are achieved, and the automatically discharging devices can be disassembled and is adjustable to fit for the gas and liquid separations of different density contrasts, and the segregator is especially fit for a natural gas production occasion.

Description

technical field [0001] The invention relates to the technical field of oil production gathering and transportation in an oil field, in particular to crude oil and gas separation equipment, which is a separator with an automatic gas and liquid discharge device. Background technique [0002] At present, oil and gas separation equipment is widely used to separate crude oil from natural gas during oil production, gathering and transportation. Although the existing oil-gas cyclone has good oil-gas separation effect, the separator itself cannot realize the automatic control of the exhaust and liquid discharge process. The Chinese patent notification number is CN1295024C, which provides a high-efficiency self-adjusting cyclone gas-liquid separator. Automatic control generally needs auxiliary systems such as automatic instrumentation devices to realize, the technology is complicated, the cost is high, and maintenance is troublesome. There are liquid level automatic control separat...
