西南石油大学邀请到卿海若教授做讲座

卿海若教授为加拿大里贾纳大学地质学系，前系主任，终身教职，现任加拿大石油地质学杂志主编。1993年1月-1995年10月为加拿大联邦政府地调部研究员，1995年10月- 1998年12月为英国伦敦大学，皇家霍洛威学院地质系讲师，2010年-2012年为加拿大里贾纳大学加籍华人教授协会主席。

卿海若教授将岩石学与地球化学的分析手段相结合，对不同大地构造背景下盆地演化、流体运移与成岩后生变化的关系、对碳酸盐岩储层（尤其是对白云岩）形成机理与模式及其对油气储层的影响进行了深入系统的研究，提出了一系列独到的见解。卿海若教授有关白云化的观点已被总结在世界知名杂志有关白云化进展的综合文章里，并广为引用。卿教授对白云化研究的贡献，尤其是热液白云化的贡献得到了世界同行的认可。卿教授独立或牵头承担25 项科研项目，研究经费1240万加圆，包括加拿大国家自然科学基金项目280 万加圆；发表论文120 篇，其中SCI 收录论文80篇；国际会议摘要121篇。曾多次主持重大国际会议。根据谷歌学者2017年2月的统计，卿教授发表论文被引用的次数为2421次；H-指数为26。

报告内容主要有：The proceof dolomitization and formation of dolomite reservoirs

have been a controversial topic for a long time. Since late 80’s, a number of

detailed case studies from the Western Canada Sedimentary Basin (WCSB) suggested

that hydrothermal fluids played a vital role in formation of massive dolomite

and associated reservoirs. In recent years, hydrothermal dolomitization has

received so much attention, which has become a new bandwagon that has been

applied indiscriminately to some case studies in Tarim Basin in China where the

hydrothermal dolomite were, actually, distinctively different from those of

WCSB.

The hydrothermal dolomites from the WCSB generally occurred in an

open system that delivered Mg as well as heat to the reaction site; whereas most

of hydrothermal dolomites in the Tarim Basin occurred in a closed or semi closed

system, where Mg is mostly derived via chemical compaction of precursor

dolomite. This fundamental difference resulted in a number of unique

petrographic and geochemical characteristics of hydrothermal dolomites in two

different basins.
