Abstract

The invention provides a multiphase metering mixed transportation method and a multiphase metering mixed transportation system, and relates to the technical field of oil well mixed transportation. The multiphase metering mixed transportation method comprises the following steps of obtaining the water content of a to-be-transported multiphase fluid, and sending the to-be-transported multiphase fluid into a first separation tank, so that liquid in the multiphase fluid in the first separation tank is deposited in the first separation tank; converting a gas separated from the first separation tank into the high-pressure gas, feeding the high-pressure gas into a second separation tank, and discharging the high-pressure gas through the second separation tank; obtaining the water content of the to-be-conveyed multiphase fluid, and conveying the to-be-conveyed multiphase fluid into the second separation tank, so that enabling liquid in the multiphase fluid in the second separation tank to be deposited in the second separation tank; and converting gas separated from the second separation tank into the high-pressure gas, and feeding the high-pressure gas into the first separation tank. The technical problem that in the prior art, in the oil and gas exploitation process of an oil field, the metering effect of a gas phase and a liquid phase in a mixed transportation device is not ideal is solved.

Description

technical field [0001] The invention relates to the technical field of oil well mixed transportation, in particular to a method for multiphase metering and mixed transportation and a multiphase metering and mixed transportation system. 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 multiphase metering and mixed transportation method and a multiphase metered and mixed tra...
