Turbidite Reservoir Prediction Based on Inversion Technique——A Case Study in Binxian Uplift of Dongying Sag
As a typical lithologic reservoir,rurbidite reservoir has a bright exploration and development prospect.This paper,taking the third turbidite section of Shahejie formation in the east slope of Binxian uplift as an example,illustrates its characteristics in Dongying sag,like"deep burial,small size,thin thickness and lime-bearing",carefully analyzes the forma-tion conditions,geological sedimentary features with turbidite reservoirs description methods to realize the reservoir prediction.The multi-parameter lithology identification technology is used to effectively sort out turbidite sandstone from lime-bearing sandstone and lime-bearing mudstone.In addition,based on the deep learning porosity physical property prediction method,this paper aims to effectively realize turbidite reservoir prediction,with good results in the application of Binxian uplift area in Dongying sag,which has been proved by actual drilling,with a prediction accuracy of 86％,signifying reference significance for the predic-tion of turbidite sandstone reservoirs and oil-gas resources in the turbidite sandstone of Binx-ian uplift and other areas.
