【摘要】 通过对彰武断陷地震相反射结构的精细地震层序解释和追踪,采用彰武断陷地震相主测线和联络测线(平行物源方向和垂直物源方向)对其反射结构的组合分类进行了分析,区分了研究区的沉积相的展布以及彰武断陷沉积相分布形态确定扇体的扇根、扇中和扇缘的空间展布范围,并对彰武断陷的沉积相分布形态进行了更精细的描述。研究表明,研究区物源由北部和东部的3个扇体共同提供,其中彰武2-3井区发育北部物源,彰武2井区为东部物源,彰武3井区为东部发育的另一物源。更多还原

【Abstract】 By analyzing the shape and distribution of facies,through fine interpreting and tracing the seismic sequences of the seismic facies reflection configuration of Zhangwu Depression,the combination is classified and analyzed for indicate the distribution of the facies in the research area,it is the direction of the provenance in the direction perpendicular to the provenance.In this way,the spacial distribution ranges of the different parts of the fans are determined and fine description for the shape and distribution of the facies in Zhangwu Depression is carried out.According to the analysis result,the provenance of the study area is composed of three fans from the north and east.The Wellblock ZW2-3develops the north provenance,the Wellblock ZW2develops the east provenance,and the Wellblock ZW3develops another provenance from the east.更多还原
