Description

Technical Field

[0001] The utility model relates to the field of separation technology equipment for petroleum exploitation, in particular to an integrated venting and liquid separation tank skid-mounted. Background Art

[0002] In the process of oil extraction, the crude oil extracted from the oil well is generally a three-phase mixture of oil, gas and water. The three-phase substances in the crude oil can be separated by a separator to facilitate subsequent refining and processing.

[0003] The oil-gas-water three-phase separator in the prior art generally has a gas-liquid separation zone and an oil-water separation zone. After the crude oil is introduced into the oil-gas-water three-phase separator, it first flows into the gas-liquid separation zone, so that the gas is precipitated from the liquid, and the gas is discharged through the exhaust port to achieve gas-liquid separation. After that, the oil-water mixture that has undergone gas-liquid separation is introduced into the oil-water separation zone. Due to the different densities, the crude oil and water in the oil-water mixture are separated by gravity sedimentation, and finally the crude oil and water are collected separately to achieve the purpose of oil-gas-water three-phase separation. However, in actual use, the liquid separation device still needs to install connecting pipes on site, which is not only difficult to install, but also inconvenient to carry and occupies a large area.
