Theory, Technology and Practice of Unconventional Petroleum Geology

0 INTRODUCTION The breakthroughs in unconventional petroleum have a great impact on world petroleum industry and innovation in petroleum geology(Dou et al,2022;Jia,2017;Zou et al.,2015b,2014a;Yerkin,2012;Pollastro,2007;Schmoker,1995).The exploration and development evolution from conventional petroleum to unconventional petroleum and more and more frequent industrial activities of exploring petroleum inside sources kitchen have deepened theoretical understanding of unconventional petroleum geology and promoted technical research and development(Jia et al.,2021,2017;Jin et al.,2021;Zhao W Z et al.,2020;Ma Y S et al.,2018,2012;Zou et al.,2018b,2016,2009;Dai et al.,2012).We have introduced and extended the theory of continuous hydrocarbon accumulation since 2008 and published several papers/books(in Chinese and English)with respect to unconventional petroleum geology since 2009,basically forming the theoretical framework for this discipline(Yang et al.,2022a,2021a,2019a,,2015a;Zou et al.,2019c,2017b,2014a,,2013a).In this paper,we present the background of unconventional petroleum geology,review the latest theoretical and technological progress in unconventional petroleum geology,introduce relevant thinking and practices in China,and explore the pathway of unconventional petroleum revolution and multi-energy coordinated development in super energy basins,hopefully to promote the unconventional petroleum geology and industry development.

安徽淮北煤成气形成条件及其资源

安徽淮北石炭、二叠纪煤系有机质丰度高，热演化程度已达高成熟阶段，生气潜力很大。本区一次生气条件因构造活动遭到相当程度的破坏。但燕山期强烈的岩浆侵入和地区西部及北缘中、新生代大幅度沉降提高了有机质热演化程度，创造了二次生气的有利条件。石炭、二叠纪煤系三角洲相沉积砂岩，及中、新生界砂岩是良好的储集层。石炭、二叠系和中、新生界粘土岩构成盖层。石炭、二叠系中有上、中、下三组生储盖组合。石炭、二叠系并与中、新生界组成另外的生储盖组合。本区寻找煤成气的有利地区是中部的蒋河向斜、南坪向斜。
