The accuracy characteristics of control over productivity of liquid, oil and gas on wells
Ukrainian Metrological Journal
World practice shows that due to improper management of the oil production process, up to 40 % of the reserves of oil fields identified during exploration are mined. One of the main reasons for this is an incorrect quantitative assessment of the accuracy characteristics of the measurement information obtained in measuring the productivity of oil wells used in taking management decisions. The accuracy characteristic of the measuring information depends on the error of the measuring instruments
... uring instruments used and, at the same time, on the errors arising from the influence of other factors on the measurement. Among the operational measuring devices of the yield of oil wells, the type group measurement device "Trap" is the most reliable and rational. Considering that the algorithms for controlling of the yield over gas, over oil and over the general liquid of oil wells contain many periodically measured parameters and tabulated data, the measurement and determination of which is influenced by a sufficient number of factors, then as an accuracy characteristics of measurement of the yield it is expedient to use the uncertainty of measuring the yield for separate components. Determining of the uncertainty of measuring the yield of oil wells along with the improvement of measurement quality leads to an effective management of well operation.
