Abstract:The Es4 member in Wangxie 119 area is a typical area where lateral reservoir variation is successfully predicted with lagging-constrained inversion technology in recent years.Structural-lithalagical reservoir is the principal reservoir pattern in the area.Es4 member,whose dominate lithalagy is lime and shale sand,varies tremendously in its horizontal direction.Since there is mare limestone in its periphery,the difference in velocity between sand and shale is small.Therefore,in order to precisely reveal the productive accumulation zone,coherence technology was used to delineate faults and matching technique of reservoir-characteristic curve in frequency domain was used to reconstruct well lags,which was used far lagging-constrained inversion and reservoir prediction can be done.It is confirmed by drilling results and the method is feasible and has a high successful rate of drilling.
