Abstract

The invention belongs to the technical field of oilfield production, and particularly relates to a movable type oilfield production metering device and a metering method. The movable type oilfield production metering device at least comprises a carrier vehicle, a liquid flowmeter, a two-phase separator, a data analysis mechanism, a gas flowmeter, a cable, a gas phase filter, a liquid phase filter,a liquid output pipe and a gas output pipe. The two-phase separator and the data analysis mechanism are both installed on the carrier vehicle, the two-phase separator is provided with an inlet end and an outlet end, and the outlet end comprises a liquid outlet and a gas outlet. The liquid outlet of the two-phase separator is sequentially connected with the liquid filter and the liquid flowmeter through the liquid output pipe, and the gas outlet of the two-phase separator is sequentially connected with the gas phase filter and the gas flowmeter through the gas output pipe. In the oil-gas mixedtransportation and gathering process, the multiphase metering technology of the oil-gas mixture is mature, the value is accurate, the oil field production management is facilitated, radioactive substances are avoided, the cost is reduced, and the movable type oilfield production metering device and the metering method can be widely used in the oil field production process.

Description

technical field [0001] The invention belongs to the technical field of oilfield production, and in particular relates to a mobile oilfield production metering device and a metering method. Background technique [0002] The relevant technical indicators of oilfield production wells (stations) are an important means to describe the injection-production status and development effect of oilfields, and are very important for adjusting oilfield injection-production and gathering and transportation processes, and improving production efficiency and management level. [0003] The crude oil in the reservoir contains dissolved gas or even gas cap gas, so the oil well output is generally associated gas, which will be released in large quantities during the resource extraction process, and enter the ground gathering and transportation system together with the oil-water mixture, and the oil and gas are mixed and transported downstream Centralized processing at the station. At present, i...
