摘要
以新疆油田B区块10口探井及开发井的静态地质数据为基础,选取孔隙度、渗透率、含油饱和度、有效厚度等4项核心参数,通过独立性分析权重法与熵值法的耦合,构建了一套静态参数分类评价标准,利用10口验证井数据进行校验。结果表明,这套分类评价体系可将B区块的井划分为Ⅰ类井、Ⅱ类井、Ⅲ类井,分类结果与实际采产量吻合度达到90%。
Based on the static geological data of 10 exploration wells and development wells in Block B of Xinjiang Oilfield,four core parameters such as porosity,permeability,oil saturation and effective thickness were selected.Through the coupling of independence analysis weight method and entropy method,a set of static parameter classification and evaluation criteria was constructed,and the data of 10 verification wells were used for verification.The results show that this classification and evaluation system can divide the wells in Block B into Class Ⅰ wells,Class Ⅱ wells and Class Ⅲ wells.The classification results are in good agreement with the actual production by 90%.
