Distinguishing Features of Gas Condensate Fields with Underground Gas Storage

Аннотация

ract The paper demosnstrates that research methods of underground gas storages (UGS) gas wells in the decided regimes have more distinguishing features than analogous research methods of pure gas and gas condensate fields wells. Besides the parameters defined on the research results of gas fields wells it is necessary to determine a and b coefficients of the UGS wells accepting ability during gas injecting. It is shown the accuracy of determination of layer pressure average value in UGS is very significant, because this index is used as reliability (surface layers) value of UGS cap of gas injection. Otherwise, the UGS will put out of order and all gas reserve in the storage mixing with atmosphere will lose. Herein distinguishing features between the UGS and pure gas and gas condensate fields is shown and well № 450 of UGS are analyzed, indicator diagram is set up and values of a and b coefficients (during gas injection) are determined.
