哈山地区三叠系层序地层特征研究

Triassic sequence stratigraphic characteristics study on Hashan area

  • 摘要: 利用层序地层学原理,对哈山地区三叠系的钻井、测井、地震、岩心等资料进行分析,识别出一个I级层序界面,二个III级层序界面,将三叠系划分为三个III级层序(TSQ1、TSQ2、TSQ3)和六个体系域。TSQ1主要发育冲积扇扇中-扇缘-扇三角洲平原沉积,TSQ2以扇三角洲前缘-平原沉积为主,TSQ3主要为滨浅湖沉积环境。TSQ1层序的冲积扇扇中砂砾岩层,主要发育在盆地边缘,与断裂或不整合相结合,仍可成为较好的储集层。TSQ2层序的扇三角洲前缘分流河道是最有利的储集相带。

     

    Abstract: By using the theory of sequence stratigraphy,through drilling,logging,seismic,core data analysis of Triassic system in Hashan area,one class-I and two class-III sequence interfaces have been identified out.The Triassic system can be divided into three class-III sequence interfaces(TSQ1,TSQ2,TSQ3)and six system domains.In TSQ1,it mainly developed alluvial fan-fan edge-fan delta plan sedimentary system.In TSQ2,it mainly developed fan delta front-plan sedimentary system.In TSQ3,it mainly developed shore-shallow lacustrine sedimentary system.The gravel strata from alluvial fan in TSQ1,mainly developed on the edge of the basin,with the combination of faulting or unconformity and it can still be good reservoir.Fan delta front distributary channel in TSQ2 was the most favorable reservoir facies belt.
