基于Surfer的网格法储量计算研究

Researching on reserves calculation using gridding method based on Surfer software

合理、准确地计算石油地质储量是指导油气田勘探开发、确定投资与建设规模、评价油气田资源性资产的重要依据。传统的容积法对非均质储层存在诸多的不适应性。而网格法能够充分考虑储层的非均质性,实现纵横向任意尺度的储量计算。探讨了网格法计算储量的原理,并应用surfer地质绘图软件进行了网格法储量计算研究,该方法在胜利油区某井区其计算结果与实际容积法相比,效果更佳。

It is important reference that calculating reserves reasonably and correctly in guiding oilfield exploratory development,determining investment and construction scale and evaluating resource asset of oilfield.Conventional volumetric method is not applicable in heterogeneous reservoir,but gridding method considers the heterogeneity thoroughly,and relizes the arbitray scale reserves calculation in vertical and horizontal.the author dissured the principle of reserves calculation using gridding method and apply surfer software to carry out it.It has got good results in the application of Shengli oilfield.
