摘　　要：在分析制约渤南洼陷主力含油层系储量空白区勘探的关键问题及对策基础上,提出一套以"剩余资源→油藏类型→成藏主控因素→储量空白区成因→勘探关键技术"为主线的精细勘探思路和方法,并在研究区开展了实践。结果表明:渤南洼陷南部斜坡带沙三段储量空白区仍具有勘探潜力;岩性-构造类油藏是潜力区可能发育的油藏类型,油藏分布受储层展布特征控制,圈闭有效性主要受构造、储层、断层封堵性及含油高度等因素控制;储层条件差、断层不封堵及含油高度低为储量空白区成因;科研攻关形成了有利储层预测、圈闭有效性及含油高度定量评价的关键技术,取得了较好的勘探部署效果。研究结果对于中国东部其他陆相断陷盆地主力含油层系的精细勘探具有借鉴意义。Based on the analysis of the key problems and countermeasures of restricting the exploration of main oil-bearing strata in the blank reserve area in Bonan sag,a set of fine exploration ideas and methods with the main line of"surplus resources→reservoir types→main controlling factors of accumulation→origin of the blank reserve area→key technologies of exploration"have been formed and put into practice in the research area.The results showed that Es3 in the southern slope belt of Bonan sag still had great exploration potential,lithologic-structural reservoir might be the possible reservoir type in potential area;the distribution of oil and gas reservoirs was controlled by the reservoirs distribution characteristics,trap effectiveness was mainly controlled by structure,reservoir,fault sealing and oil-bearing column;poor reservoir condition,poor sealing fault and low oil-bearing column were the genesis of the blank area of reserves.The key technologies of favorable reservoir prediction,trap effectiveness and quantitative evaluation of oil-bearing column have been formed through tackling key problems,and good exploration deployment effect has been achieved.The results had reference significance for fine exploration of main oil-bearing series in other continental fault basin in east China.
