Abstract: Based on the fact that the principal factor controlling the recoverable reserves in fractured reservoirs is fracture and the close relationship between fracture development and structural curvature,a method of estimating reserves with the application of seismic profiles is proposed. Physical and geological bases of the method are discussed and steps of calculation are described,together with the computation and analysis of some theoretical model profiles for illustration.A gas field of fractured carbonate reservoir in Sichuan is taken as an example for estimation of reserves.

摘要： 本文对裂缝性储集层的储量计算提出了一种新的方法。文章论述了裂缝与构造曲率的密切关系,利用曲率值研究裂缝发育状况,岩层受构造力作用拱曲后体积增量即裂缝所占的空间。地下水作用引起裂缝发生变化,利用容积有效系数作储集空间的校正,进行储量估算。
