Modificationofmolecularstructure on Reservoir Surface While Low-Pressure Gases Cenomanian Deposits Exploitation

Abstract

In the article principal problems of Cenomanian gas reservoirs exploitation on the last stage are considered. On the base of primary data analysis the dependence of a gas saturation factor from vertical reservoir location against gas water contact is determined which has influence on the gas well exploitation method. The necessity of maintenance of a net gas pay in a productive layer remaining the same during water shutoff treatment is proved. A new approach for realization of water shutoff treatment within low-pressure gases exploitation is justified.
