摘要
以岩石学、古生物学和地震地层学理论为指导思想,详细介绍了在辽东湾地区如何以钻井、地震资料为基础,建立岩性、电性特征及其对比关系;建立古生物组合鉴别特征,总结不同古地理演化对生物地层的影响;认清研究区内各基本地层单位的地震反射特征及其在三维空间内的变化规律;从而确定地层的正确对比关系,解决了东营组内部地层矛盾问题,同时探讨了地层与油气分布关系,为今后的地层研究及相关的勘探工作提供了有益指导。
Based on the study of petrology、paleontological and seismic stratigraphy,in this paper we detail methods of using drilling、 seismic data to establish Lithology,electricity character contrast relations;to establish paleontology assemblage distinguishing characteristics;to sum up different paleogeographic evolution's effect on biostratigraphy;to recognize the rule of seismic reflection characteristics and 3D spatial change in study block.At the same time,we discuss the relationship of stratum and hydrocarbon distribution,in the end,we solve the problems which have arisen in the exploration and the results provide guidance for oil and gas exploration.
