On Calculation Method of Dynamic Reserve of Low-permeability Reservoir Single Well

Confirming gas well dynamic reserve is the basis of reasonable production allocation and setting development plan.But because of low permeability and strong anisotropism,it's difficult to calculate the exact dynamic reserve.According to it,this paper analyzes the calculation method of dynamic reserve,and introduces flow material balance method to dynamic reserve calculation of low permeability.It discusses the characteristics of production dynamic curve,proposes the calculation method of it.The analysis shows that flow material balance method needs less data and the result of it is reasonable and reliable.
