摘　　要：浊积岩油藏作为一种典型的岩性油气藏,具有良好的勘探开发前景。本文以滨县凸起东坡沙三段浊积岩为例,针对东营凹陷浊积岩油气藏“埋藏深、个体小、厚度薄和含灰质”等特点,对其形成条件、地质沉积特征进行了深入剖析,重点介绍了针对浊积岩油藏的储层预测描述方法、技术,使用多参数联合岩性识别技术有效区分浊积砂岩与含灰质砂岩、灰质泥岩;另外,研究设计基于深度学习孔隙度物性预测方法,有效开展浊积岩储层预测。该技术在东营凹陷滨县凸起地区的应用中取得良好效果。部分目标经钻井证实,结果预测吻合率达86%,对滨县地区及其他地区浊积岩砂岩储层预测具有借鉴及参考意义。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 formation 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 prediction of turbidite sandstone reservoirs and oil-gas resources in the turbidite sandstone of Binxian uplift and other areas.
