Abstract

The invention relates to the technical field of oil-gas-water treatment in oil fields, and provides a full-gravity balance separation and dehydration integrated device in order to realize simple and efficient oil-gas-water separation of crude oil, which comprises a first tank body and a second tank body, an oil-gas-water separation cavity is arranged in hte first tank body, a sedimentation water purification cavity, a sedimentation oil purification cavity and an alternating current and direct current dewatering cavity which are not communicated with one another are formed in the second tank body, the first tank body is connected with the second tank body through downcomers, the downcomers comprise an oil purification cavity downcomer and a water purification cavity downcomer, the two ends of the oil purification cavity downcomer are communicated with the oil-gas-water separation cavity and the sedimentation oil purification cavity, and the other ends of the water purification cavity downcomer are communicated with the oil-gas-water separation cavity and thesedimentation water purification cavity. The invention further provides a crude oil treatment method of the full-gravity balance separation and dehydration integrated device, the device can complete crude oil dehydration by completely adopting pressure energy of liquid coming from a well mouth without additional pressurization, energy consumption is saved by more than 50%, and the crude oil purification short-process treatment process of the high-water-content oil field is realized.

Description

technical field [0001] The invention relates to the technical field of oil, gas and water treatment in oilfields, in particular to a full gravity balance separation and dehydration integrated device and a crude oil treatment method. Background technique [0002] The oil-gas-water three-phase separator is currently the most commonly used oil-gas-water treatment device in the process of oilfield development and production. The working principle of the three-phase separator: the oil-gas-water mixture enters the pre-degassing chamber at high speed, and a large amount of crude oil associated gas is released by cyclone separation and gravity. Wash and demulsify in the active water layer containing demulsifier, stabilize the flow, reduce the Reynolds coefficient of the incoming liquid, and then flow into the sedimentation separation chamber after coalescing and rectification for further sedimentation and separation. The degassed crude oil enters the oil chamber through the partitio...
