摘要
描述了新立油田扶杨油层裂缝发育的特征和规律。通过从沉积相类型、储层岩石学特征、主要成岩作用、区域构造背景、新构造演化的角度来分析该区低渗透裂缝性砂岩储层形成的原因,认为沉积、成岩作用是形成低渗透储层的原因;钙质胶结为主的砂岩是裂缝形成的岩性基础;在区域构造背景以及该区特定构造演化的作用下,最终导致了新立油田扶杨油层呈现低渗透裂缝性的特征。
Feature and law of fracture development in Fuyang oil layers of Xinli Oilfield are described.On the basis of sedimentary type,reservoir lithology feature,major diagenesis,areal structure setting and Xinli structure evolution,generation reason of low permeable fractured reservoir in this area is analyzed,considering sedimentation and diagenesis as dominant causes for the formation of low permeable reservoir.Sandstone prominently composed by calcarinate is the lithologic basis of forming fracture.Both the areal structure setting and specific structure evolution cause the features of low permeable fracture for oil layer in Xinli Oilfield.
