UDK: 622.276.5.05.002.56
DOI: 10.24887/0028-2448-2019-3-86-91
Key words: horizontal well, flow meter, reverse flow, flow rate, well equipment calibration, multiphase flow

The quality analysis of flow measurements shows there are 35% of successful measurements and 65% from total are satisfactory. Separation of studies of production profile and injection profile demonstrate that the applicability of flow measurement is lower than quality of injection flow measurement. The most frequently assumed reason for the low applicability of flow measurements is high magnitude of minimum threshold flow meter or its pollution. Important parameters such as fluid composition and borehole deviation in the research interval are not taken into account but they influence on final results. Test analysis of production flow meters of Russian manufacturing for two-phase fluid (oil-water) was done using simulation pipes that may change their deviation. These tests were carried out at Innovation Campus of Technopark located at Bashkir State University in coordination with service companies. It has been found that fluid composition and borehole deviation change influence on flow meter response no mater of fluid type complexity. Also it does on quality of interpretation results. Test results in simulation pipes are demonstrated through examples of production wells (vertical and horizontal). Prospects for obtaining flow parameters in wells and improving the quality of flow measurement data are considered.
