鄂尔多斯盆地定边—庆阳地区长7段致密油烃源岩地质数据挖掘与评价
Geological data collection and assessment of tight oil source rock of Chang-7 from Dingbian to Qingyang region in Ordos Basin, China
摘要
Abstract
Geological anomaly theory,multiple technical approaches of factor analysis,trace elements analysis,trend surface analysis and data normalization treatment are used to discuss the controlling factors and distributive characteristics of the effective source rock of Chang-7 Member of Triassic Yanchang Formation in Ordos Basin.A method of geological data collection and information integration on the source rock of Chang-7 Member is proposed.It is indicated that the biological burst of the lower aquatic paleo-organisms (type index of organic matter) and degree of thermal evolution of organic matter are the main controlling factors to the development of effective source rock under the background of a generally high content of total organic carbon.The relatively concentrated distribution of effective rock is generally located in the south Jiyuan,west Dingbian,east Youfangzhuang,Huachi area and the northeast Heshui,which indicates a certain degree of relating and controlling effect on the zones of tight oil high production.The study reveals that the favorable direction for future exploration and exploitation of tight oil in Chang-7 Member includes the area from Gengwan to Huanxian,the north Huachi,Youfangzhuang to Wucangpu area and the Dingbian area.关键词
