Abstract In order to solve the problem of low prediction resolution for fan delta front thin sand body,the authors,considering basic geological characteristics of Nv59 fault-block in the Shenusi oilfield,utilized the advantages and disadvantages of the constrained sparse spike inversion and geostatistics inversion method,predicted sand body of Ek21 of this block,and evaluated the effectiveness of the geological effect of the calculated result.According to different well densities and different underground geological conditions,the authors chose adaptive inversion result.Compared with conventional methods,geostatistics inversion based on characteristic curve structuring is more suitable for single body prediction in development areas with dense wells.In areas where the wells are scarce,constrained sparse spike inversion is more suitable for prediction of thick sand group.This technique has guided the development of Ek21 oil sands at Nv59 fault block effectively.
