Abstract

The invention provides an oil well water mixing digital flowmeter calibration device and method. The device includes a standard flowmeter used for providing a calibration reference value, a water supplying tank used for providing testing water, and a control module used for conducting calibration on a to-be-calibrated flowmeter according to the calibration reference value; the to-be-calibrated digital flowmeter, the standard flowmeter and the water supplying tank are in series connection with one another to make the testing water flow through the to-be-calibrated digital flowmeter and the standard flowmeter, and the control module is electrically connected with the to-be-calibrated digital flowmeter and the standard flowmeter to determine the error value of the to-be-calibrated digital flowmeter according to output values of the to-be-calibrated digital flowmeter and the standard flowmeter.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a calibration device for digital flowmeters mixed with water in oil wells. Background technique [0002] The technological process of oil well recovery can be as follows figure 1 As shown, each oil well needs to produce oil from the ground at a depth of 1,200 meters, and then transport it to the metering station through a long single-well pipeline. After dehydration and precipitation of crude oil at the joint station, the qualified crude oil is sent to the first station, and the remaining sewage is sent to the water injection station. Part of the sewage from the water injection station is injected back into the ground, and part of it is sent to the water mixing station to mix water at the wellhead of the oil well. [0003] Oil wells in some areas of our country have the characteristics of high viscosity, poor fluidity, and difficult ground transportation. Therefore, during lon...
