用传统容积法计算储量时,由于对储层参数采用的是平均值而忽略了储层的非均质因素,影响了储量计算的准确性。针对容积法的这一不足,采用了建立地质模型、以网格为单元进行储量计算的方法,提高了储量计算的准确性。应用G ridstatpro地质统计学建模软件成功地实现了某碳酸盐岩气藏精确地质模型的建立,进行了储量计算,结果比传统方法较佳。

When we calculate reserves with traditional cubature, parameters of reservoir bed we use are average values. This ignores anisotropic factors of reservoirs, so that affects accuracy of calculate. To solve thisproblem, we built geologic model, and calculated reserves with the model's network data. In this method, we can increase accuracy of calculate. In this paper, we successfully applied GRIDSTATPRO, a kind of modeling software, to build an accuracy geologic model of a real gas reservoir in carbonate rock. And we also calculated reserves, according to data of our model. Compared with the traditional cubature, our result is better, because that our model meets the case of reservoir nature better. In addition, we investigated exploitable reserves of the real gas reservoir, with several methods.
