摘要/Abstract

摘要： 探讨陆相致密油藏差异化含油特征与控制因素可支撑致密油藏储层评价、深化致密油藏储层认识。通过致密油藏宏观分布、岩芯观察、油藏条件、单井产能4个方面对比分析，揭示海相、陆相致密油藏均普遍存在差异化含油现象，陆相致密油藏差异化含油具有“分布散、范围宽、差异大”的特点；通过岩芯描述、薄片鉴定、测井解释、开发区解剖等方式，阐明了准噶尔盆地吉木萨尔凹陷芦草沟组致密油藏不同尺度条件下均表现出强烈的差异化含油特性，在井位优选、井轨迹和压裂改造设计中正越来越受到重视；进行了致密油藏差异化含油控制因素探讨，提出沉积相、成岩相、断裂体系及源储配置等因素决定了致密油藏含油性的宏观差异化分布，储层层理、物性、孔隙结构、微裂缝等因素控制了致密油藏储层局部含油性差异化分布。

Abstract: This study discusses the different oil-bearing characteristic and control factors of continental tight oil to support reservoir evaluation and increase knowledge on such reservoirs. Contrast analyses were conducted, such as macro distribution of tight oil, rock core observation, reservoir conditions, and single well productivity. The results reveal that different oilbearing phenomena exist both in marine and continental tight oil. In continental tight oil, the oil-bearing characteristics are decentralized distribution, a wide range, and large differences. Techniques such as core observation, slice identification, logging interpretation, and development area anatomy analysis clarified the oil-bearing characteristic of the Lucaogou tight oil in the Jimusaer Depression, Junggar Basin, showing obvious differences at different scales. Increasingly, attention is being paid to the optimization of well location, well trajectory, and fracturing design. In addition, the controlling factors of tight oil differentiation and oil bearing distribution were discussed. The factors that determine the macroscopic distribution of oil-bearing are the sedimentary facies, diagenetic facies, fault system, and the source storage configuration. Factors such as the reservoir beds, physical properties, pore structures, micro fractures, and others control the local distribution of the tight oil differentiation oil-bearing.

Key words: tight oil, differentiation, oil-bearing, Jimusaer Depression, Lucaogou Formation
