摘　　要：烃源岩为油气成藏提供了重要的物质基础,特别是良好的源储配置关系是致密油成藏的关键因素之一。以鄂尔多斯盆地HD地区C8非常规致密砂岩油藏为例,通过开展烃源岩生烃能力评价、成藏组合关系规律研究,建立了四种源储配置关系模式,结合产能影响的工程因素,综合评价“烃源岩-地质-工程”甜点,明确油气富集规律,指导开发生产。Source rocks provide an important material basis for hydrocarbon accumulation. In particular,the favorable source-reservoir configuration is one of the key factors for hydrocarbon accumulation of tight oil. In this paper,a case study is performed for the unconventional tight C8 reservoir in the HD area of Ordos Basin. Through the evaluation of the hydrocarbon generation capacity of source rocks and the investigation of the law of reservoir combination,four source-reservoir configuration models are identified. Moreover,the built models,combined with the engineering factors affecting productivity,are used to comprehensively identify the“source rock-geology-engineering-integrated”sweet spots and clarify the hydrocarbon enrichment regularity,in an attempt to provide guidance on the development and production.
