CHARACTERISTICS OF OIL GENERATION IN COMPRESSIONAL SUPERIMPOSED BASINS IN NORTHWEST CHINA
-
摘要: 中国西北地区面积260×104km2,已发现100多个油气田,油气资源十分丰富.经几十年的研究和勘探,归纳总结出了西北地区压性叠加盆地成油特征:多旋回演化、构造变形复杂、多时代烃源岩、多套储盖组合、多期成藏、独特油气藏特征及油气分布规律等.Abstract: The area of northwest China is 260×104km2 and more than 100 oil and gas fields have been discovered in the area.It has rich hydrocarbon resource.The characteristics of oil generation in compressional superimpositional basins were summarized after tens years of exploration and study.They are Characte-rized by polycyclic evolution,complicated tectonic deformation,multiple-age source rocks,multiple combinations of reservoirs and seals,multistage accumulation,and unique properties and distribution of oil and gas fields.
