ANALYSIS ON PETROLEUM CONDITIONS AND EXPLORATION POTENTIAL IN BURGOS BASIN, NORTH OF MEXICO
-
摘要:
墨西哥湾盆地是世界著名的油气富集区，也是当今世界油气勘探的重点和热点区域。墨西哥位于墨西哥湾西南侧，油气资源丰富，油气勘探活动始于19世纪，盆地陆上以气为主，海域以油为主。通过对墨西哥北部博格斯（Burgos）盆地的区域构造背景、石油地质条件以及油气成藏模式等进行综合分析认为，盆地构造类型多样，西部发育伸展构造，东部发育挤压构造；烃源岩基础好，发育多套烃源岩；储盖组合发育，储层物性较好；东侧挤压褶皱区构造发育，油气成藏条件优越，具有较好的勘探潜力。
Abstract:The Gulf of Mexico Basin is a famous oil-bearing basin in the world. It has been an important hotspot of world hydrocarbon exploration for years. Mexico locates to the south west of GOM with rich oil and gas resource. Exploration work in this basin started in 19th century, there are gas discoveries onshore and oil discoveries offshore. This paper made a comprehensive study on regional tectonic background and geological conditions together with hydrocarbon accumulation model. Study results show that the basin have many types of structures, extensional structures develop in the west while compression traps in the east. There are several high-quality source rocks, well developed reservoir-seal combinations and sandstones with good physical properties. The eastern compression fold area of the basin has excellent petroleum accumulation conditions and great exploration potential.
