摘　　要：运用地震地层学原理 ,在孔二段中识别出八种地震相单元。结合岩心、测井和各地震相单元所处的古地理位置 ,给予各地震相以沉积学的解释。指出孔二段发育两种沉积体系 ,扇三角洲沉积体系主要发育于洼陷边缘 ,而湖泊体系则位于洼陷中心。综合分析表明 。Based on the principle of seismic stratigraphy, eight kinds of seismic facies unit are identified in Kong2 member. Combined with some data about core, well logging and ancient geographic location of each seismic facies unit, each seismic facies is interpreted by sedimentation and it is indicated that there are fan delta depositional system and lake depositional system in Kong2 member. Fan delta depositional system mostly developed in subsag margin, but lake depositional system always located in subsag center. The comprehensive analysis indicates that there are potentials of hydrocarbon generation and accumulation in Kong2 member.
