Seismic Reservoir Prediction Of The Sha ? Succession Of The Wen38 Block Of The Zhongyuan Oilfield

This thesis has integrated seismic and wireline logging data to study tectonic characteristics,seismic reservoir prediction and structure-sand combination pattern of the Wen38 Block in Wenliu area,Dongpu Depression of Zhongyuan Oilfield.305 fault points and 53 faults are recognized through well-seismic exquisite interpretation,and 3 category,7 types of extension structure pattern are classified.Additionally,this study has also classified 4 different levels of faults,established the distribution role of the depositional faults within the Wen38 Block.There have been four tectonic stages occurring in the Wen38 Block: initial rifting,intense rifting,strike-slip rifting,and stable depositional stages.Using the model of the linear programming sparse-spike inversion to predict reservoir distribution,combining with complex fault blocks in the study area,the sand prediction method of “inversion-directed,structure-controlled,well log-restricted” is determined,which is directed by inversion sand-body distribution map,controlled by fault features regionally,restricted by well data and complete prediction of sand-body distribution.Then the distribution rules of favorable reservoir are studied.This thesis provides a new idea and of the seismic reservoir inversion technology for predicting sandbody distribution in complex faulting zones.
