Abstract

The invention relates to the technical field of oil well metering devices and methods, in particular to an integral automatic well selection metering device and a multi-process automatic oil well output metering method. The integral automatic well selection metering device comprises a multi-way valve, a vertical gas and liquid separator, a liquid drain pump and an RTU (remote terminal unit), wherein a single well metering liquid outlet pipeline, a multi-way valve liquid outlet pipe and at least one single well oil collecting pipeline are fixedly arranged on the multi-way valve; the other end of the single well metering liquid outlet pipeline is communicated with a material inlet of the vertical gas and liquid separator; a liquid level meter is arranged on the vertical gas and liquid separator and is used for monitoring the liquid level in the vertical gas and liquid separator. The integral automatic well selection metering device has the advantages that the structure is reasonable and compact; by combining capacity type metering and mass flow meter metering, the single well liquid metering range is wider, the indirect type metering is realized, the instantaneous type metering is also realized, and the metering accuracy is higher; by adopting an integrated prying device, the construction and installation at site are convenient and rapid, the construction workload is decreased, and the construction cycle is effectively shortened.

Description

technical field [0001] The invention relates to the technical field of oil well metering devices and methods, and relates to an integrated automatic well selection metering device and a multi-process automatic metering method for oil well production. Background technique [0002] The metering stations currently in use in oilfields mainly adopt the construction mode of multi-way valves or well selection manifolds and metering devices; the metering mainly adopts volumetric metering. In recent years, some oilfields use mass flow meters to measure wellhead production fluid. However, due to the complexity of the actual production in the oil field, there are the following problems: [0003] 1. The measurable range is small and the limitations are large [0004] Currently used metering devices mainly use volumetric or flow meter metering methods. Volumetric metering is actually intermittent metering, and liquid phase metering is based on the corresponding liquid level accumulation...
