FIELD: oil and gas production industry.
SUBSTANCE: invention relates to the oil and gas production industry and can be used for gas-hydrodynamic survey and operation of gas, gas condensate and oil wells. Method includes measuring the flow rate, formation, bottomhole and wellhead pressures, temperatures at the wellhead of the i-th well, where i = 1, 2, 3, …, n, on each of the modes operating simultaneously into the cluster well pipeline, for each of which the coefficients of the filtration resistance A and B are determined. In this case, up to (n-1) simultaneously operating cluster wells are sequentially disconnected from one of the cluster wells selected randomly, and curves of dependence of the quadratic depression and its ratio to the production rate from the production rate are plotted for the cluster wells at different modes, along which the coefficients of the filtration resistance A and B are determined.
EFFECT: technical result of the invention consists in the expansion of functionality, which involves the ability to survey wells located in the cluster, while simultaneously working in the well pipeline, which, in turn, improves the accuracy of obtained data and extends the range of well survey, as well as reduce the period of surveying all cluster wells with increased productivity.
