Prediction technology for Paleogene turbidite reservoirs in W oilfield of Weixi'nan Sag
The Paleogene turbidite reservoir is characterized by deep burial,small bodies and strong con-cealment of W oilfield in Weixi'nan Sag,it is difficult to identify the turbidite reservoir by conventional ex-ploration technology.Due to under-compaction,low-velocity mud stone develops in the study area,which further increases the difficulty of turbidite reservoir prediction.In view of above problems,a set of technology for turbidite reservoir prediction in Weixi'nan Sag was summarized by studying seismic extension frequency and amplitude preserving processing and acoustic curve reconstruction.This technology has been applied to exploration and development practice,and has achieved good results,indicating that this technol-ogy has a good guidance and popularization value for lithologic reservoir exploration in the whole basin.
