摘要
储层非均质特征评价是储层特征研究很重要的一部分内容 ,储层非均质特征是描述储层的参数变化及非均质特性 ,非均质性的强弱直接影响着开发方案的设计和实施。本文以尕斯库勒油田N1-N12 油藏砂西区Ⅱ油组为例 ,研究储层非均质性特征。用来描述储层非均质性的特征参数主要有 :连通系数、重叠系数、夹层厚度、夹层频数以及均值、最大值、最小值、变异系数、级差、非均质系数。
Assessment of reservoir heterogeneity is an important part of the study of reservoir features. It describes heterogeneity and change in various parameters of a reservoir. The heterogeneity has an influence on exploitation of the oil field. This paper deals with heterogeneity of oil group Ⅱ in N1-N1 2 oil reservoir in Shaxi area, Gas Hure Oil Field, including such parameters as connectivity, overlapping coefficient, interbed thickness, interbed frequency, variation coefficient, coefficient of anisotropy and so on.
