Abstract

A piston-type volumetric fluid metering device and a metering method relate to the metering field of the produced fluid of oil wells, and are used to solve the problem that the traditional oil tank manual chi-square metering method consumes a lot of manpower and material resources in the metering of the produced fluid of oil wells, has a big hidden danger of safety and environmental protection inthe vehicle-based transportation of produced fluid after metering and has large error and the problem on how to meter the produced liquid of a pouring-type oil well and a pipeline transportation oil well. The automatic control of the device is realized by connecting a control center with all detection elements. The volume of the produced fluid of an oil well is recorded, and the phenomenon of consumption of a lot of manpower and material resources is avoided. A piston-type metering approach is adopted. Because the volume of the cylinder block is fixed, the produced fluid of the oil well is injected into the cylinder block, and a metering unit filled with liquid is formed through reciprocating motion of the piston, the approach can greatly reduce the metering error. The piston-type volumetric fluid metering device and the metering method of the invention are applicable to the metering of the produced fluid of oil wells.

Description

technical field [0001] The invention relates to the metering field of oil well output fluid, in particular to a piston type volumetric fluid metering device and a metering method. Background technique [0002] At this stage, there are mainly three methods of measuring oil well produced fluid in my country's oilfields: manual chi-square measurement of oil storage tanks, tipping bucket measurement and mass flow meter measurement. At present, the traditional manual chi-square metering method for oil storage tanks is generally used, which consumes a lot of manpower, material resources and financial resources, and the measured liquid needs to be transported to the joint station by car, which has great potential safety hazards; and the tipping bucket metering method is due to The complexity and intermittency of oil well production fluid, as well as the disadvantages of its own structure, lead to large measurement errors; and mass flowmeters are difficult to be widely used in oil w...
