近年塔里木盆地雅克拉断凸及周缘地区下白垩统亚格列木组岩性圈闭勘探取得重要进展，为了明确该区亚格列木组碎屑岩储层沉积相展布规律，促进碎屑岩储层的高效勘探开发。通过利用岩心、测井、三维地震等资料的方法，研究了塔里木盆地雅克拉断凸及周缘地区白垩系亚格列木组沉积相类型及空间展布特征，以源汇理论为指导分析物源区特征对扇三角洲的发育的控制作用。结果表明：雅克拉断凸及周缘地区亚格列木组发育扇三角洲群沉积。在亚格列木组沉积时期，雅克拉断凸地区的古隆起具有明显的分段性，呈北东东向的条带状隆起，呈现东、西两个凸起，中部地势低的特征。基于源-汇体系分析，明确扇三角洲群沉积物源来自古隆起风化剥蚀区域，多支古沟谷为扇三角洲群沉积提供了沉积物输送通道。可见古地貌、沟谷发育特征等控制着雅克拉断凸及周缘地区亚格列木组源-汇体系，形成多物源供给的沉积格局，古隆起西段主要表现为高隆起、沟谷面积较大；东段主要表现为低隆起、沟谷面积较小。物源区沟谷的发育规模控制了古隆起周缘三角洲沉积展布规模。古隆起以南发育缓坡型扇三角洲沉积体系，以北发育陡坡型和缓坡型扇三角洲沉积体系。源-汇体系分析降低了亚格列木组沉积相研究的不确定性，可以为油气勘探提供更多地质依据。

In recent years, important progress has been made in the lithologic trap exploration of the Lower Cretaceous Yageliemu Formation in the Yakela fault convex and its surrounding areas in the Tarim Basin, in order to clarify the sedimentary facies distribution law of the clastic rock reservoir of Yageliemu Formation in this area, and promote the efficient exploration and development of the clastic rock reservoir. Based on an integrated analysis of core samples, well logging data, and 3D seismic surveys, the sedimentary facies types and spatial distribution patterns of the Cretaceous Yageliemu Formation in the Yakela fault convex and its surrounding areas in the Tarim Basin were investigated. Furthermore, under the framework of source-to-sink system theory, the controlling effects of source area characteristics on fan delta development were systematically examined. The results show that fan delta group deposits are developed in the Yageliemu Formation in the Yakela fault convex and its surrounding areas. During the deposition period of the Yageliemu Formation, the ancient uplift in the Yakela fault convex area was obviously segmented, with a banded uplift in the NEE direction, with two bulges in the east and west, and a low terrain in the middle. Based on the analysis of source-sink system, it is clear that the sediment source of the fan delta group is from the weathered denudation area of the ancient uplift, and the multi-branch ancient gullies provide sediment transport channels for the fan delta Group. It can be seen that paleogeomorphology and gully development characteristics control the sour-sink system of Yageliemu formation in the Yakela fault convex and its surrounding areas, forming a sedimentary pattern with multiple sources supply. The western ancient uplift is mainly characterized by high uplift and large gully area, the eastern section is mainly characterized by low uplift and small gully area. The development scale of gullies in provenance area controlled the distribution scale of deltaic sediments around ancient uplift. The gentle slope fan delta sedimentary system developed in the south of the ancient uplift, and the steep slope and gentle slope fan delta sedimentary system developed in the north. The analysis of source-sink system reduces the uncertainty of sedimentary facies study of Yageliemu Formation and can provide more geological basis for oil and gas exploration.
