2010年2月1日和2月4日,斯坦福大学外聘顾问教授ken Peters分别在斯坦福大学地球与环境系和能源系做了关于三维油气成藏系统模拟和地球化学在油气成藏系统模拟中的关键作用的报告,报告区别了油气成藏系统模拟和盆地模拟,并称三维油气成藏系统模拟时代已经到来。
三维盆地模拟或油气成藏系统模拟是一项工作量很大的复杂系统工作,它涉及到多个领域如构造地质学、沉积学、地质年代学、地球化学及盆地模拟等技术,因此是多方面的研究工作者集体的工作。
目前在中国,一维、二维模拟早已开始,但三维模拟很少见。三维模拟在中国不仅涉及到技术方面的问题,也涉及到团队合作的问题,这与团队意识和领军人物的缺乏不无关系。国内科研队伍的领军人物很多已转变为行政式的领导,对研究队伍也采用行政式管理,他们自己很多已不参与学术研究,这种团队及管理方式很难让三维油气成藏模拟行之有效。

Schlumberger and Stanford University Exploration Paradigm Shift: The Dynamic Petroleum System Concept
When: 4:15 pm, Monday, February 1
Where: Geocorner 105
The traditional approach to exploration is based on finding subsurface traps for petroleum. This static view ignores the fact that petroleum systems consist of complex elements and dynamic processes that control whether present-day traps are barren or filled with oil and gas (hydrocarbons). This talk describes recent
advances in geochemistry and a paradigm shift from static to dynamic understanding of petroleum systems, which we call the ‘dynamic petroleum system concept’. The talk also introduces the term “basin and petroleum system modeling” (BPSM) to emphasize the difference between basin modeling, which deals with rocks, and petroleum system modeling, which deals with hydrocarbons. To quantify petroleum systems, one must first model basin geohistory. Basin modeling applies mathematical algorithms to seismic, stratigraphic, paleontologic, petrophysical, well log, and other geologic data to reconstruct the deposition and erosion of rock
layers through space and time. Petroleum system modeling begins after creation of the basin model and when effective source rock exists in the basin. A petroleum system consists of four essential elements (source,reservoir, seal, and overburden rock) and two processes (trap formation and generation-migrationaccumulation;
Magoon and Dow, 1994). Petroleum systems occur in sedimentary basins, but not all sedimentary basins contain petroleum systems.
