摘要:
苏北盆地高邮凹陷阜宁组二段(以下简称阜二段)页岩油勘探获得突破,是未来增储上产的现实目标。裂缝作为储集空间和运移通道,在页岩油勘探开发中发挥着重要作用。以X1井为研究对象,根据成像测井、岩心和微观薄片观察结果,分析了高邮凹陷阜二段页岩油储层不同尺度裂缝发育特征;结合裂缝参数统计和裂缝充填物稳定碳氧同位素分析,确定了裂缝形成期次,讨论了裂缝动态演化过程及裂缝对页岩油气富集的影响。结果表明:构造裂缝总体较为发育,主要为脆性剪切裂缝和张剪性裂缝,剪切裂缝长度长,横向连通性好;非构造裂缝主要为层理缝和顺层方解石脉,在部分亚段异常发育。不同类型的天然裂缝后期均遭受了一定程度的改造,未被完全充填的裂缝、裂缝充填物溶蚀形成的孔洞,以及超压层理缝和微裂隙,均是页岩油有利的储集空间。研究结果为高邮凹陷深层页岩油选区、选段提供了新的思路和理论依据。
