【摘要】 龙潭组是苏北地区重要的生油层和储集层和勘探目的层。龙潭组残存状况、砂岩储层分布范围、烃源岩晚期生烃范围、构造变形程度及浦口组盖层发育程度是控制该套组合油气成藏的主要因素。论文充分利用地震、钻井资料,在构造模式的指导下预测了龙潭组残存范围。开展了龙潭组砂岩储层特征研究。结合龙潭组埋深确定了其有效生烃范围。在浦口组盖层评价及海相中、古生界构造变形强度分析的基础上,综合评价海安—黄桥—南通地区为龙潭组勘探有利区。更多还原

【Abstract】 Permian Longtan Formation is an important target layer for marine origin petroleum exploration in north Jiangsu area.The primary factors to control the play are the residual Longtan Formation distriubutrion,sand reservoir rock distribution,secondary hydrocarbon generation scope,structural deformation degree and cap rock(Pukou Formation)development.The residual distribution of Longtan Formation is predicted in this article by seismic interpretation,drilling data analyzing and guidance of structural model,Haian- Huang Qiao- Nantong region is the most favorable area for Longtan Formation oil and gas accumulation based on the sandstone reservoir rock feature of Longtan Formation,the effective oil and gas generation scope,cap rock(Pukou Formation)evaluation and marine layer deformation analyzing.更多还原
