全球油气地质几个重大问题的思考

A discussion on some key problems about the global petroleum geology

经多年研究和实践,认为全球有关油气地质差别很大,从地壳运动动力、海陆变迁与大陆地块形成演化、原型盆地类型、油气资源潜力及油气发展战略和方向出发,提出几个重大问题进行初步讨论,如地球构造运动起源、地球海陆变迁特征、古生界变质作用、矿产资源形成与破坏、油气战略思考和调整方向。多年来,对上述几个重大问题的探索和科学研究,特别对全球油气勘探发展战略和方向具有重大指导意义。

Based on years＇ study and practice, the author considers that conditions of global petroleum geology are varied. In the light of dynamic mechanism of plate motion, type of ancestral basin, hydrocarbon resource potential, development strategy and trend for the oil-gas resources, the authors put forward some important problems for tentative discussion, which include original unity of mechanisms of global tectogenesis, sea- land changes, Palaeozoic metamorphism, formation and destruction of resources and development strategy and trend for the oil-gas resources. The study and discussion of these problems in recent years are of important guiding significance especially for development strategy and trend for the oil-gas resources.
