摘要
针对川中-川南过渡带嘉二段储层地质特征,选择反映储层宏观和微观特征的参数作为储层评价因子,通过各因子与储集性的相关分析建立储层评价标准。依据模糊数学评判法,对储层进行多因素综合分类评价,在评价中引入层次分析法确定因子的权重。在单井分类评价的基础上,做出各小层储层分类评价平面分布图。经储层综合评价,揭示出各类储层分布规律,为油气勘探提供可靠的地质依据。
In combination with the geologic characteristics of Jia2 member in Chuanzhong-chuannan transitional zone, the parameters reflecting macroscopic and microscopic reservoir characters are chosen for factors of evaluation, criteria for reservoir evaluation are established for correlation analysis of each factor and reservoir properties. Based on fuzzy mathematic evaluation, a multi-factor integral and classification evaluation is conducted on the reservoir, in which a hierarchical analysis method is employed to determine the weight of factors. On the basis of single well evaluation, a distribution chart of small reservoir classification evaluation is plotted, the distribution laws of each reservoir are presented by integral reservoir evaluation, for the purpose of providing a reliable basis for oil and gas exploration.
