摘　　要：裂缝是致密储层流体渗流的主要通道,裂缝的发育、分布规律控制着裂缝性油气藏的分布。介绍了裂缝定量预测的研究方法及原理,分析了楚雄盆地的地质概况,并结合研究区的地质特征,应用屈曲薄板应力场模拟法、构造主曲率法对楚雄盆地北部致密储层裂缝开展定量预测研究。研究表明,裂缝定量预测结论与野外露头剖面考察及钻井岩心裂缝发育规律吻合较好,说明该方法用于开展裂缝定量描述是可行的。Fracture is a main type of fluid flow path in tight reservoir rocks,and its development and distribution may control the formation of fractured hydrocarbon reservoirs.The fractures in tight reservoirs in the northern Chuxiong basin are quantitatively studied by using the stress field simulation of flexural plate and the main structure curvature,according to the methodology and principles of fracture quantification and an analysis of the basin geology.The results show that these predicted fractures are quite consistent with those from crop and drilled core observations ,indicating this approach feasible for fracture quantification.
