摘　　要：为了弄清也门X区块下白垩统地层的沉积相特征和评价其潜在的含油气性,运用了地震相和测井以及地震层速度等综合分析手段,分析了区内下白垩统的沉积相,认为下白垩统主要为一套陆棚背景的陆源碎屑—碳酸盐岩的混合沉积,主要包括混积潮坪亚相、混积内陆棚亚相和混积外陆棚亚相,在此基础上指出,研究区的西南侧含砂量大,离物源近,可作为有利勘探区。To find out sedimentary facies features of the Lower Cretaceous formation of X block in Yemen, and evaluate its potential oil and gas bearing characters, we use comprehensive methods, such as seismic facies, logging and earthquake interval velocity etc, to analyse the Lower Cretaceous sedimentary facies in the area. We think the Lower Cretaceous formation is mainly a set of terrigenous clastic-carbonatite deposition in a continental shelf environment, chiefly including the mixed deposited tidal shoal parfacies, the mix deposited inner shelf parfacies,and the mixed deposited outer shelf parfacies. At the same time, the southwest side, where sand content is large and near provenance,can be a favorable place for exploration.
