摘　　要：毛里塔尼亚海岸盆地位于非洲西部大西洋东岸,是典型的中新生代被动大陆边缘盆地。近年来海上已经发现2个油田,但在陆上尚无发现。通过对盆地烃源岩、储盖层、运移条件及圈闭等成藏地质条件的分析,对盆地陆上区域油气资源与勘探潜力进行了探讨。研究区内源岩生烃能力有限,可能的油气资源主要来自于西部海域成熟源岩。结合油气运移条件,认为本区具备一定的勘探潜力。The Mauritania Coast Basin represents a classical passive margin basin created in response to the opening and drift of the Atlantic Ocean,which began in the Late Permian/Early Triassic times.Two oil fields have been discovered in the offshore area,but not any onshore.On the base of the petroleum geology,such as hydrocarbon sources,reservoir,seal formations,trap and migration conditions,the petroleum resource and exploration potential have been discussed in the paper.Migration of petroleum from the offshore area is considered to be important because of the absence of discovered source rocks in the study area.According to the migration conditions,it is concluded that the onshore area has a certain petroleum exploration potential.
