METHOD OF GAS DYNAMIC INVESTIGATION OF WELL FOR LOW-PERMEABILITY RESERVOIRS

摘要

FIELD: oil and gas industry.;SUBSTANCE: method of gas dynamic testing of wells for low-permeability reservoirs comprises measuring Q_i and bottomhole pressure P_bi of investigated well at n different modes in the i-th, where i=1, 2, 3, …n at arbitrary time intervals τ_i, between the i-th and the initial research modes. Formation pressure for investigated well is determined at arbitrary moments of time by measuring formation pressure in nearest well located under observation located in the drainage zone of investigated well.;EFFECT: increased efficiency when carrying out gas-dynamic tests due to reduced cost of working time for conducting investigations and improved accuracy of obtained results.;2 dwg, 2 tbl
