摘　　要：滨县凸起东坡在沙三段中、下沉积期具有山高坡陡的构造特征,浊积砂体广泛发育。本文在分析了陡坡带浊积砂体的地质、地震特征的基础上,结合目前深水浊积砂岩勘探开发面临的埋藏深,变化快,含油性难确定等难点,研发了一套高精度古地貌恢复技术定区,"甜心体"定砂,"高亮体"确定含油气性的浊积砂体有效储层预测技术序列,该方法适用于深湖相的浊积砂体储层描述。研究表明,"甜心体"可准确落实储层边界,"高亮体"可预测储层的含油气性,实际应用效果良好。The east slope of Binxian uplift was of ＂high hill and steep slope＂ in the depositional stage of the Middle and Lower of Es3, and the turbidite s.and bodies was developed extensively. On the basis of the analysis of the geo- logic and seismic characteristics of the turbidite sand body in the steep slope and combined with the difficulties （deep buried depth, quick change, difficult to confirm the oiliness） in turbidite sand exploration and development, a set of effective turbidite sand reservoir prediction technique （high precision palaeogeomorphology restoration tech- nique to confirm the area, ＂sweetness body＂ technique to confirm turbidite sand body, ＂highlight body＂ technique to confirm hydrocarbon bearing property） were developed, which is suitable to describe the turbidite sand reservoir in deep lake facies. The result show that the ＂sweetness body＂ technique can be：,~sed to .accurately define the boundary of the reservoir, the ＂highlight body＂ technique can be used to predict the hydroe.arbon bearing property of the reservoir and a good result is obtained in practical application. ..i ：
