New method study on development dynamic evaluation of Zizhou gas field

After six years of rolling development,Zizhou gas field shows bigger differences on single well production productivity for dynamic performance,and the present dynamic evaluation method cannot be adapted to development.Therefore,new methods of evaluating gas formation pressure,namely the golden section method and production data optimization fitting capacity evaluation method have been put forward.The calculation example shows that the two methods are of high calculation accuracy and practical,which can meet the practical requirement engineering calculation.
