塔里木克拉通盆地油气勘探对策

塔里木克拉通盆地包括整个盆地“三隆四坳”^[1]中的塔北隆起、北部坳陷、塔中隆起、巴楚隆起等主要构造单元（见图1）。经多年勘探，目前已探明和发现了众多油气田（藏）：塔北隆起上的轮南、塔河、东河塘等油田，塔中隆起上的塔中4、塔中16油田，巴楚隆起上的和田河气田、巴什托甫油田，北部坳陷中的哈得逊油田等。这些海相成因的油气主要富集在奥陶系碳酸盐岩与石炭系、三叠系、侏罗系砂岩储集层中，来源于寒武系和中上奥陶统两套烃源岩。

Oil and gas exploration strategy in Tarim cratonic basin

Tarim cratonic basin is a marine multiple cyclic basin with multiple oil migration and charging. The strategy of oil exploration to cratonic basin is based on the controlling degree to the oil distribution. According to the analyses of typical oil reservoirs in Tazhong, Tabei, Hadexun, Bachu, it can be concluded that oil distribution in cr atonic basin is controlled by 8 hydrocarbon supplying centers in geological per iod. In this basin there are three oil migration and charging models and Oil res ervoirs were adjusted by two times. So the strategy of oil exploration must be b uilt according to the oil distribution law. In different plays there are differe nt oil bearing layers and oil reservoir types.
