本文阐述了塔里木盆地北部雅克拉—轮台地区构造变形规律、变形特征和变形演化史 ,指出雅克拉—轮台变形带控油的因素主要有 :长期发育的古隆起、断裂的多期活动、不整合面的叠置发育、有利的控油构造样式及控油因素的空间合理配置、构造活动史与油气移聚史合理匹配和优良的储盖组合 ,其中古隆起、断裂及不整合面三者乃是形成油气田的重要因素。此外 ,还详细论述了该区负反转构造控油的特点和弧形断裂控油的机理 ,并提出了近期勘探的首选目标。
In this paper, the tectonic deformation, deformation characteristics and deformation evolution history of the Yakela-Luntai area in northern Tarim Basin are described. It is pointed out that there are mainly oil-controlling factors in the Yakela-Luntai deformation belt, such as long-term developed paleo-uplift and fault multi-period activities, The superimposed development of the integrated surface, the favorable oil control structural style and the space allocation of the oil controlling factors, the rational matching of the tectonic activity history and the history of migration and accumulation of oil and gas, and the excellent reservoir-cap assemblage, of which the paleouplift, fault and unconformity are An important factor in the formation of oil and gas fields. In addition, the characteristics of oil control in negative inversion structure and the mechanism of arc fracture oil control are discussed in detail, and the first target of recent exploration is proposed.
