下刚果盆地油气成藏条件非常有利,尤其盆地内沉积了阿普第阶盐岩层,发育多种类型盐相关构造,形成多种类型圈闭,同时盐岩层又是非常好的盖层。但该套盐岩层的存在也使下刚果盆地盐下、盐上油气成藏条件产生较大差异:盐下地层油气成藏的主控因素为伸展构造有关的圈闭,未来重点勘探仍以寻找伸展构造有关的油气藏类型为主要方向;盐上白垩系油气成藏的主控因素为圈闭和储层,未来勘探应以寻找与阿尔布阶Pinda组碳酸盐岩和Vermelha组的滨岸砂岩为储层并与盐构造相关的油气藏为重点;第三系油气成藏的主控因素则为烃源岩成熟度、圈闭及浊积砂体的发育,未来重点勘探方向为寻找深水—超深水区盐构造与浊积砂体复合型油气藏。
The hydrocarbon accumulation conditions in the Lower Congo Basin are very favorable. In particular, the Apudstone salt rock is deposited in the basin, and various types of salt-related structures are developed to form various types of traps. At the same time, the salt rock is a very good cap rock. However, the presence of this set of salt strata also causes great differences in hydrocarbon accumulation conditions in the Lower Congo Basin. The main controlling factors of hydrocarbon accumulation in the sub-salt stratum are extensional structure-related traps. In the future, the key exploration is still looking for Extension and tectonism. The main controlling factors of Cretaceous hydrocarbon accumulation in salt are traps and reservoirs. In the future, exploration should be carried out to find the shoreline of the Pinda Group Carbonate and Vermelha Formation in the Albu-Plains Sandstone is the reservoir and the emphasis is on the oil-gas reservoirs related to the salt structure. The main controlling factors for the hydrocarbon accumulation in the Tertiary are the maturity of source rocks, the development of traps and turbidites, and the key exploration direction in the future is to find deep water Salt structure and turbidite complex oil and gas reservoir in ultra deep water area.
