Abstract: The collision of two different tectonic plates often formed a series of orogenic bellts,andled to the formation foreland basins along the front with the relatively stable plates.Majorforeland basins in China include: front of Kuche depression in Tarim basin,front of Kunlunmountains in the southwest of Tarim basin,front of Algin mountains in the southeast ofTarim basin,south margin of Zhugar basin,front of Bogda mountains eastern of Zhugarbasin,front of Helan-Liupan mountains and two foreland basins in southern China.All ofthese foreland basins are highly prospected areas for oil and gas exploration.

摘要： 由于两个板块的相互碰撞形成一系列造山带,而在稳定板块的前缘常常形成前陆盆地.由于前陆盆地的特点,使它对油气的生成、运移、聚集和保存都十分有利.中国的主要前陆盆地有:塔里木盆地库车坳陷前缘、塔西南昆仑山前缘、塔东南阿尔金山前缘;准噶尔盆地南缘、准噶尔盆地东部博格山前缘;贺兰山一六盘山前缘;南方地区的两个前陆盆地.这些前陆盆地都是寻找油气前景广阔的地区.
