摘要
文东地区沙三中亚段具有重力流沉积特征。斯伦贝谢的 HDT 和 SHDT 测井经 DIPLOG 和 GEODIP 程序处理结果,用来研究沉积相已见成效,划分出浊积岩相、风暴岩相等。该区有两种事件沉积:(1)滨浅湖的风暴重力流;(2)半深湖—深湖的纵向重力流和滑塌重力流;两种正常沉积:(1)浅湖—深湖的泥质沉积;(2)盐湖等深流沉积。风暴重力流、纵向重力流和滑塌重力流中的“ABAB”序和“BBB”序中—细砂岩是油气聚集的有利场所。
The middle formation of s_3 member in Wendong area has features of deposition from gravity flow.It is available to study sedimentary facies by DIPLOG or GEODIP from HDT or SHDT of Schlumberger Co.There are turb- idites,tempesites and so on in Wendong area.There are two types of event depositions:(1)storm gravity flows in lakeshore-shallow lake,(2) longitudinal gravity flows and slide gravity flows in semideep lake—deep lake facies,and two types of common depositions:(1) lacustrin mud deposits,(2) iso-deep flows deposits of salt lake.The “ABAB”,“BBB”sequences middle-fine grained sandst- ones in longitudinal gravity flows,slide gravity flows and storm gravity flows are favorable for oil and gas accumulation.
