摘要
Based on core,logging,testing and 3D seismic data,by viewpoint of "well spot analysis-combination inversion/formation thin section-sandbody interpretation model-sandstone trapped tracking-trap optimization",this paper presents the lithological trap prediction and optimization research of the Jurassic Sangonghe formation in Baijiahai swell.And JASON sparse pulse inversion and ISIS global simulation annealing inversion are applied to develop the sandbody recognition model,by which the total 13 lithological traps have been recognized in the first member of Sangonghe formation,which are mostly distributed in southwest slope area and two sides of nose-like swell,favorable for the oil-gas accumulation.Also,based on multi-factors analysis of oil-gas accumulation control,No.8 and No.9 lithological traps are selected to be drilled at Baijia-2 and Baijia-3 wells,and good drilling results have been gained.
