Multiphase metering and mixed transportation system and multiphase metering and mixed transportation method

Abstract

The invention provides a multiphase metering and mixed transportation system and a multiphase metering and mixed transportation method, which relate to the technical field of oil well mixed transportation. The multiphase metering and mixed transportation method includes the following steps: obtaining the water content of the multiphase fluid to be transported, and into the first separation tank, so that the liquid in the multiphase fluid in the first separation tank is deposited in the first separation tank; the gas separated in the first separation tank is converted into high-pressure gas, and the high-pressure gas is sent into the first separation tank Two separation tanks, and the high-pressure gas is discharged through the second separation tank; obtain the water content of the multiphase fluid to be transported, and send it to the second separation tank, so that the liquid in the multiphase fluid in the second separation tank is in the second separation tank Deposition in the second separation tank; convert the gas separated in the second separation tank into high-pressure gas, and send the high-pressure gas into the first separation tank. The method solves the technical problem of unsatisfactory metering effect of the gas phase and liquid phase in the mixed transportation device in the process of oil and gas exploitation in the oil field existing in the prior art.

Description

technical field [0001] The invention relates to the technical field of mixed transportation of oil wells, in particular to a multiphase metering and mixed transportation system and a multiphase metering and mixed transportation method. Background technique [0002] During oil and gas extraction in oilfields, the produced fluid either contains a mixture of gas and liquid, or a mixture of solid, gas and liquid, which is difficult to pump directly. Therefore, separation treatment is usually carried out first, so as to facilitate separate transportation. [0003] In the separation technology of the gas phase and the liquid phase, the existing technology can realize the separation of the two, but the metering effect of the gas phase and the liquid phase in the mixed transportation device is not ideal. Contents of the invention [0004] The purpose of the present invention is to provide a multi-phase metering and mixed transportation system and a multiphase metering and mixed t...
