在理想化微构造模型基础上用微构造计算地层顶面曲率,利用储层微构造的曲率来研究火成岩储层中构造裂缝的分布与预测.以渤海湾盆地惠民凹陷中的商河油田商741井区沙三中亚段浅层侵入火成岩裂缝储层为例,利用储层裂缝微构造曲率预测法对储层裂缝进行研究,提出了在浅层侵入火成岩中利用曲率变化值来预测裂缝发育程度的曲率预测法的改良方法.结果表明:该方法在商741井区的应用较为理想,利用缝面比参数法对商741井区沙三中浅层侵入火成岩曲率变化值与裂缝发育的相关性进行了分析,相关系数R2在0.79以上.
Based on the idealized micro-structure model, the curvature of the top surface of the strata is calculated by using the micro-structure and the curvature of the micro-structure of the reservoir is used to study the distribution and prediction of structural fractures in igneous reservoirs.Based on the Shanghe Oilfield in the Huimin Sag, Bohai Bay Basin Taking the shallow intrusive igneous rock fractured reservoirs in the middle S3 of Shahejie Formation as an example, reservoir fractures are studied by means of reservoir fracture micro-structure curvature prediction method, and the prediction of fracture development by using the change of curvature values in shallow intrusive igneous rocks The results show that this method is ideal for commercial well 741, and the method of seam face ratio is used to analyze the relationship between the change of the rock igneous rock and the development of fractures Sex analysis, correlation coefficient R2 above 0.79.
