Description

technical field [0001] The invention relates to the field of oil fields, in particular to a single-well metering device and method suitable for oil wells. Background technique [0002] Single-well metering of oil wells is a necessary means to obtain data for dynamic analysis of oilfield development. Due to the relatively short cycle of conventional oil well metering, many oilfields have mostly used multi-well metering stations for many years. At present, there are six methods commonly used in oil well measurement in oil fields at home and abroad: (1) measuring oil in horizontal elevated tanks; (2) measuring oil in glass tubes; (3) measuring oil with electrode liquid level; Liquid level recovery method; (6) Gongtu method. Among them, the horizontal elevated tank oil measurement method, the glass tube flowmeter and the tipping bucket oil measurement method, because the measurement method is relatively primitive, the labor intensity of the workers is high, the accuracy is low,...

AI Technical Summary

Problems solved by technology

Among them, the horizontal elevated tank oil measurement method, the glass tube flowmeter and the tipping bucket oil measurement method, because the measurement method is relatively primitive, the labor intensity of the workers is high, the accuracy is low, and the reliability is poor, especially the measurement of the production of super heavy oil wells. Slow, the gas content is not easy to discharge, it needs to settle for more than 4 hours, and real-time online measurement cannot be realized; Data, it is difficult to automatically identify the power map by the computer, and some empirical parameters are required, which has a large human factor, resulting in large measurement errors and unsatisfactory use effects

These have brought huge bottlenecks to the promotion of oil well automation technology
