Oil-gas-water three-phase separator

Abstract

The invention provides an oil-gas-water three-phase separator. The ontology of the invention is divided into a settling chamber, a water chamber and an oil chamber; a sewage discharge outlet, a water outlet and an oil outlet are respectively arranged at the bottom parts of the settling chamber, the water chamber and the oil chamber; an oil / gas / water inlet, a spiral energy divider and a gas outletare respectively arranged at two ends of the body; a maze-shaped oil-gas separating plate which is formed by connecting a plurality of circular corrugated plates with a plurality of grooves through bolts, a plurality of evenly distributed through holes are formed on each corrugated plate, and the positions of the through holes on the adjacent corrugated plates are staggered mutually; a heating pipe and a temperature probe which is connected with a control cabinet are arranged at the front part of the oil-gas separating plate; and a water level detecting head and an oil level detecting head which are both connected with the control cabinet are respectively arranged in the water chamber and the oil chamber. The oil-gas-water three-phase separator effectively improves the separation effect and the separation efficiency of oil-gas-water, realizes the automatic control of a water-oil interface, leads the oil-gas metering result to be synchronous with the energy of a well head and reflects the real-time transient change of the yield of the well head.

Description

technical field [0001] The invention belongs to the technical field of petroleum exploitation, in particular to an oil-gas-water three-phase separator. Background technique [0002] In the process of oil extraction, the extracted crude oil contains associated oil, natural gas and water, which need to be separated. The existing oil-gas-water three-phase separator has a general structure: the horizontal cylindrical body is divided into a sedimentation chamber, a water chamber and an oil chamber by a spill plate and an oil overflow plate; the sedimentation chamber, the water chamber and the oil chamber The bottom is provided with a sewage outlet, a water outlet and an oil outlet; one end of the body is provided with an oil-gas-water inlet and an energy separator, and the other end is provided with an air outlet; an oil-gas separation plate with several through holes is also provided in the water chamber. And there is an energy separator at the gas-liquid inlet. At the same ti...

AI Technical Summary

Problems solved by technology

[0003] The existing oil-gas-water three-phase separator, because its energy separator is usually tubular with a number of separation holes on the bottom surface, has a poor effect on the preliminary liquid-gas two-phase separation of the oil-gas-water mixture.

In addition, because the separator hole of the oil-gas separation plate is a straight-through type, the resistance of oil, gas and water through the separator is small, and the stroke is short, resulting in unclear separation of oil, gas and water, and poor separation effect.

Furthermore, since the opening and closing of the valves on the oil outlet and the water outlet are manually controlled, the accuracy and reliability are poor, and the opening cannot be automatically controlled to affect the separation effect.
