摘要
With the high heterogeneity,well-developed mudflow-gully and complicated distribution of the gas composition in DF1-1 Gas Field,the development effect was affected.Based on the study of sedimentary microfacies,this paper describes the reservoir heterogeneity and its cause.With the new geophysical techniques,data resolution can be improved greatly and the single sandbody can be characterized.Finally,a 3D fine geologic model is built.Based on precise reservoir description,we know the sedimentary microfacies,the origin and distribution of sandbodies and all kind of reservoir heterogeneity that influence the gas distribution.We also describe the single sandbody,the interlayer,and the boundary of mudflow gully.We build a 3D heterogeneity parameter model,describing reservoir geometry and the distribution of rock property in the space.Then,based on the results above,we optimize the type,location and trajectory of development well to balance reserve-production of DF1-1 Gas Field and enhance gas recovery,meanwhile satisfying the market demand.The results of this research provide references to reasonable development for similar offshore gas field.
