【摘要】：综合分析研究了非常规油气储集层孔隙结构、非常规油气赋存状态、充注机理、富集主控因素和高产成藏模式方面的新进展。非常规油气地质研究从纳米孔隙的观测发展到全孔径孔隙结构的定量表征和三维重构,从非常规油气赋存状态的宏观、静态特征描述发展到微观、动态演化研究,从启动压差驱动和优势通道运移发展到跳跃式阶梯充注和润湿性优势输导,从"源控论"发展到源控下的"优势源储组合+保存条件"的成藏论,从非常规油气的"富集"地质模式发展到"富集+高产"的成藏模式,展示了非常规油气地质理论的研究进展和未来的发展趋势。在此基础上指出了非常规油气地质理论、深层非常规油气富集条件和资源可采潜力、非常规油气地质研究对工程技术的渗透及非常规油气资源共采基础地质研究面临的问题与挑战。
[Abstract]:The pore structure of unconventional reservoir, the state of occurrence of unconventional oil and gas, and the mechanism of injection are comprehensively analyzed and studied. New advances in enrichment main controlling factors and high yield reservoir forming models. The study of unconventional oil and gas geology has developed from the observation of nano-pores to the quantitative characterization and three-dimensional reconstruction of the pore structure of the whole pore, and from the macroscopic view of the occurrence state of unconventional oil and gas. Static feature description has developed into microscopic and dynamic evolution, from starting pressure differential drive and dominant channel migration to jumping step filling and wettability dominant transport. From "source control theory" to "dominant source reservoir combination preservation condition" under source control, from "enrichment" geological model of unconventional oil and gas to "rich and high yield" reservoir forming model, The research progress and future development trend of unconventional oil and gas geological theory are shown. On the basis of this, the unconventional oil and gas geological theory, the enrichment conditions of deep unconventional oil and gas and the potential of resource recoverability are pointed out. The problems and challenges faced by the study of unconventional oil and gas geological research on the penetration of engineering technology and the basic geological research of unconventional oil and gas resources co-production.
