墨西哥Sureste盆地盐相关圈闭发育特征

Sureste盆地位于墨西哥湾南部，为系统研究该区盐相关圈闭。基于第1手的地质、钻井、油田和地球物理资料，从盆地构造演化阶段、沉积充填特征、盐岩活动期次出发，系统分析了圈闭成因、发育特征、空间展布规律。结合盆地勘探程度指出，Comalcalco次盆东部侏罗—白垩系盐核背斜圈闭和Reforma褶皱带中北部牛津阶和基末利阶盐核背斜圈闭、伸展盐筏断块圈闭为最有潜力勘探目标，为该盆地盐上勘探目标的优选提供了科学依据。

TYPES AND DISTRIBUTION PATTERN OF SALT RELATED TRAPS IN THE SURESTE BASIN,MEXICO

The Sureste Basin is located in the southern Gulf of Mexico and there is little discussion on this basin in literatures. In order to systematically study the salt related traps in this area, geologic, drilling, field and seismic data are used to systematically analyze the features, origins and spatial distribution patterns based upon basin tectonic evolution, sedimentary features and salt movement stages. In combination of exploration status, it is concluded that the Jurassic and Cretaceous anticline with salt cores in the Comalcalco Sub-bain are the most favorable prospecting target and the Salt core anticline, tensional salt draft fault block in the Oxfordian and Kimmeridgian Formations in the North of Reforma belt are the second. The study result is helpful for optimization of the exploration targets in post salt stratum of Mexico Sureste Basin.
