Abstract

The invention relating to the technical field of oil well measurement discloses a measuring device for the liquid production capacity of an oil well and a measuring method thereof, thereby improving the measuring precision of the liquid production capacity of the oil well. The measuring device comprises an oil reservoir, a calibrating member, a liquid level detecting member, and a PLC device. Thecalibrating member is configured to load a predetermined volume of to-be-measured oil into the oil reservoir to determine a volume pulse equivalent of the to-be-measured oil in the oil reservoir. Theliquid level detecting member arranged in the oil reservoir is configured to detect the rising height of the to-be-measured oil in the oil reservoir and transform the rising height of the to-be-measured oil into the pulse number. The PLC device is connected to the liquid level detecting member. The measuring device for the liquid production capacity of an oil well and the measuring method thereofcan be used for realizing large-scale application of the liquid production capacity.

Description

technical field [0001] The invention relates to the technical field of oil well measurement, in particular to a measuring device and method for oil well fluid production. Background technique [0002] As an important part of oilfield production management, the measurement of oil well fluid production is one of the main bases for understanding reservoir conditions and formulating production plans. Among them, the measurement of oil well fluid production refers to the measurement of intermittent crude oil output at the wellhead of the oil field. [0003] At present, there are mainly two measurement methods for the measurement of oil well fluid production. First, mechanical flowmeter measurement, for example, tipping bucket flowmeter, there is a large error between the liquid production measured by the mechanical flowmeter and the actual liquid production, usually the error is about 30%, the reason is that the mechanical The liquid production measured by the mechanical flowme...
