Summary:By analyzing the research results of internal and external scholars, the characteristics of Mesozoic sediments of the Gulf of Mexico Basin were summed up. Analysis indicated that in the late Triassic, fluvial facies, alluvial fan facies and shallow lake and the other continental facies were developed in the Gulf of Mexico Basin, and carbonate sediments were developed in the late period of middle Jurassic-the early period of late Jurassic. And from the later Jurassic to Cretaceous, the river and delta facies were developed in the updip direction, the beach bar and biological reef were developed widely around the basin, and in the downdip, the under water turbidite fen and normal marine mudstone sediments were developed. On the basis of studying the sedimentary characteristics, combined with structural evolutional background, a sedimentary evolution mode was established, and the sedimentary mode and the hydrocarbon accumulation pattern controlled by the structural evolution were analyzed. Study shows that the reef facies reservoir is the major type of reservoir in the Mesozoic System. In addition, the deepwater clastic sand bodies, such as submarine fan and slump fan are the important facies zones of oil and gas enrichment.
