【摘要】 十屋断陷、长岭凹陷深层系指营城组(K1yc)、沙河子组(K1sh)及其以下地层,其主要烃源岩沉积厚度大,生烃量占总生烃量的86%～90%。十屋和长岭两地区油气资源总量为10.41×108t油当量,资源丰度(7.46～15.09)×104t/km2,深层圈闭形成时期早、面积大,具有优先捕获油气的有利条件,加之资源探明程度低,尚处在储量发现早期阶段,资源潜力巨大,是寻找原生油气藏的重要领域。更多还原

【Abstract】 The lower part in Shiwu fault depression and Changling sag includes Yingcheng Formation(K1yc)?Shahezi Formation(K1sh)and other lower formations. The thickness of the main source rocks is large and its hydrocarbongeneration quantity is about 86%-90% of the total. The sum of gas resources is 10.4×108t oil equivalent and the resource abundance is (7.64-15.09)×104t/km2. The deeper traps formed in the early stages with large areas could have priority condition to accumulate oil and gas. Discovery of this kind of accumulation is still in its early stage because of the olw exploration degree. There is favourable potential for petroleum exploration in the area.更多还原
