Optimization of method for gas-dynamic research of wells

The rational system of development gas fields and the operation of underground gas storage facilities are directly dependent on the amount of information received from each well, i. e. the degree of study productive formation. The most important sources of information about the gas layer and the wells of gas field are the gas-dynamic methods research of wells. The research results are processed by binary equation of gas flow to the well bottom. The coefficients of filtration resistance determined in the research process are used in the future to calculate the technological operating conditions of well and gas-dynamic calculations of options for development gas deposits or cyclic operation in UGS. Studies are conducted at four or six steady state modes. However, carrying out such complex of studies for operating gas fields and UGS with the number of wells 100–300 or more due to certain difficulties. First, they require a high cost of working time and a partial declin e in productivity of deposit or UGS; and secondly, the reliability of determination research parameters is often low due to incomplete stabilization of well operation mode. The article proposes an accelerated method of research for gas wells in steady-state regimes using the power formula of gas flow to the well bottom. The application of this method to gas deposits and underground gas storage facilities of Precarpathian has made it possible to significantly accelerate the research process in wells without substantial reducing the reliability of their results.
