摘要
以研究潜江凹陷代河地区成藏含油性主控因素为目的,分析了代河地区油气成藏条件,并通过典型含油气圈闭和落空圈闭及构造因素的对比研究,得出该区成藏的主控因素在于形成有效封堵,即荆沙剥蚀面封堵、断层面封堵、砂岩尖灭线封堵为主的"两面一线"的主控封堵因素。该研究结果为今后高陡构造带开展储层及有利圈闭预测提供了方向。
For the purpose of researching the main control factors of oil-bearing property of hydrocarbon accumulation in Daihe Area,the hydrocarbon accumulation conditions were analyzed,by comparing the typical hydrocarbon traps with step-out traps and structural factors,it was concluded that the main control factor of hydrocarbon accumulation is to form a main control factor of effective blocking,which means the blocking of Jingsha erosion surface and the fault,the sandstone pinch-out line plugging ' on both sides of a line ',dominated the master blocking factors.The study provides the direction for predicting traps and reservoir in high-steep structural belt in the future.
