Abstract

The present invention relates to oil well output liquid measuring power graph method and device. Oil well liquid output is measured through analysis of the 3D vibration of oil pumping rod column, oil pipe column and liquid column and the time relationship of their displacement, speed, strain, stress and load, research of the mutual coupling of the force and displacement of these three sys, acquiring oil well relating data with load and displacement sensors, and computer treatment to calculate the effective stroke of the oil pump. Meanwhile, the present invention also performs the diagnosis and analysis of oil well work state and the remote monitoring of oil well.

Description

technical field

[0001] The invention relates to a method for metering the output fluid of an oil pumping well and an adopted device thereof. The produced liquid metering technology is not only suitable for automatic metering construction in newly developed oilfields, but also suitable for the reconstruction of surface metering systems in old oilfields. Background technique

[0002] At present, domestic oilfield oil well production fluid measurement mainly adopts technical means such as double-volume single-well measurement, wellhead tipping bucket measurement, movable metering vehicle measurement, and liquid level method.

[0003] 1. Double-volume single-well metering: This is the most common metering method, that is, the output fluid of each oil well is transported to the metering station through the oil outlet pipeline according to the well group, enters the oil-gas separator, and is separated from the gas-liquid , to measure the produced fluid, and then enter the oil gat...
