【Abstract】 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.更多还原
