异常高压气藏投产后,压降图上出现两个斜率不同的直线段。晚出现的第二直线段相当于正常气藏的直线段,可以用来推算气藏储量。本文作者利用第一直线段根据物质平衡理论推导出气藏虚拟地质储量,并建立与真实地质储量关系式,计算出气藏地质储量。 After the abnormal high-pressure gas reservoir is put into operation, two straight sections with different slopes appear on the pressure drop map. The second straight line segment appearing late is equivalent to the straight line segment of a normal gas reservoir and can be used to calculate the gas reservoir reserves. The author uses the first straight line segment to derive the virtual geological reserves of gas reservoirs according to the material balance theory and establishes the relationship with the true geological reserves to calculate the geological reserves of the gas reservoirs.
