我国海相沉积总面积大于455万km2。勘探领域广阔,资源潜力大,具有发现大中型油气田的物质基础,是我国油气资源战略接替区。制约我国海相碳酸盐岩油气勘探的主要难题是烃源岩时代老,生烃过程难恢复及生烃灶迁移;缝洞型储层非均质性强;深埋藏后优质储层形成机制复杂,预测难;多期?
The total area of marine sediments in China is more than 4.55 million km2. There is a vast exploration area with great resource potential and the material basis for discovering large and medium-sized oil and gas fields. It is a strategic replacement area for oil and gas resources in China. The main problems that restrict the hydrocarbon exploration in marine marine carbonate rocks are the old hydrocarbon source rocks, the difficult recovery of hydrocarbon generation and the migration of hydrocarbon generating stations. The heterogeneity of fractured-cave reservoirs is strong and the formation mechanism of high-quality reservoirs after deep burial Complex, difficult to predict; multi-period?
