松辽盆地东南隆起区深层断陷的构造特征及其对油气勘探的意义
|
摘要
在8km×8km测网地震资料对比解释的基础上,研究了松辽盆地东南隆起区深层断陷的发育概况,认为断陷的主要发育时期为沙河子期,发育8个不等的断陷。根据地震解释结果等相关资料,分析了断陷期火石岭组、沙河子组和营城组的分布差异。结合区域地质背景,认为松辽盆地东南隆起区深层断陷期主要经历了初始裂陷期(火石岭期)、强烈断陷期(沙河子期)和断坳转换期(营城期)3个演化阶段。对深层断陷地层遭受的改造作用进行了分析。
Based on the comparison and interpretation of seismic data obtained using an 8×8 km grid,the authors have studied the development of deep fault depressions in the southeastern uplift area of the Songliao basin and think that the fault depressions mainly developed in the Shahezian stage,when eight fault depressions of different sizes occurred.According to the results of seismic interpretation and other related data,the authors have analyzed the difference in distribution of the Huoshiling Formation,Shahezi Formation and Yingcheng Formation during the downfaulting period.Based on the regional geological setting and structures of this area,they think that the deep downfaulting period in the southeastern uplift area of the Songliao basin may be divided into three evolutional stages:the initial rifting stage(Huoshilingian stage),strong downfaulting stage(Shahezian stage) and downfaulting-downwarping transition stage(Yingchengian stage).The reworking of the deep downfaulted strata is also analyzed.
