摘要
Sands 1 of the first member of Shahejie Formation in the submarginal sedimentary system presents the weak reflection or blank reflection in the seismic profile of Chunfeng Oilfield in Chepaizi Area.Reservoir characterization is difficult.To resolve the problem,target-oriented seismic data processing and logging data standardization processing are conducted for the seismic data of the study area,and reliable basic data have been acquired.Then,based on the accurate zone interpretation,reservoir calibration and wavelet extraction are carried out and the correspondence relationship between reservoir and seismic is made clear.The wave impedance model conformed with geologic rule is established and the inversion parameters for the area are obtained through test.Finally,high-resolution wave impedance data volume is gained by the using of logging-constrained inversion.Through the analysis of the distribution rule of favorable reservoir sand body for Sands 1 of the first member of Shahejie Formation,it is believed that the near source reservoirs present a good development in the middle part and western part of the study area.The favorable reservoirs are mainly distributed in the western part and middle part of the study area.The study result provides an important reference for further hydrocarbon exploration in the area.
