Metering device of multi-way valve used for gathering and transportation

Abstract

The present invention relates to a gathering and transportation device, in particular to a metering device of a multi-way valve used for gathering and transportation. The invention adopts the technical scheme that the metering device consists of a metering tank, a liquid mixing tank, a multi-way valve, a meter, liquid inlet pipes of the multi-way valve, a liquid outlet gathering pipe, a single-well liquid intake pipe and an oil-gas-water mixed-phase transmission outlet pipe, wherein a plurality of liquid inlet pipes are arranged on the multi-way valve and respectively communicated with the single-well liquid intake pipe; the liquid outlet gathering pipe is connected with the liquid mixing tank; the metering tank is arranged at the upper part of the liquid mixing tank; the meter is arranged on the metering tank; and the oil-gas-water mixed-phase transmission outlet pipe is arranged at the bottom of the liquid mixing tank. The metering device has the benefits that the temporary production measures can be reduced, the subsequent workload is reduced, the investment is saved, the construction cycle of the oil field is shortened, and the temporary production cost can be saved. In addition, the operation is humanized and simplified, the maintenance is convenient and simple, and manpower and material resources are saved.

Description

technical field [0001] The invention relates to a gathering and transportation device, in particular to a multi-way valve metering device for gathering and transportation. Background technique [0002] For a long time, oil production gathering and transportation stations are generally built by on-site welding, fabrication and installation of steel pipes and valves. Its structure is: double rows of horizontal pipelines, vertical pipelines and valves connecting multiple oil production wells, etc., to form a crude oil gathering and transportation station, and valves, pipelines, etc. are installed indoors. The existing water metering and distribution stations have the following disadvantages: ① The construction period is long; the construction speed is slow, and it cannot meet the needs of production in a short time; ② It cannot be adjusted according to the needs of rolling development, mainly in terms of station type. Traditional The metering station (manual and automatic) bas...

AI Technical Summary

Problems solved by technology

The existing water metering and distribution stations have the following disadvantages: ① The construction period is long; the construction speed is slow, and it cannot meet the needs of production in a short time; ② It cannot be adjusted according to the needs of rolling development, mainly in terms of station type. Traditional The metering station (manual and automatic) basically adopts a brick-concrete structure, with many rooms, a large area, and high investment; ③ The oilfield management method has changed from manned duty to unattended well patrol system, and the automatic well selection metering station has more electric valves , there are many measurement and control points, and the metering and distribution stations have already shown excess functions

④ Construction conditions are limited by ambient temperature conditions
