摘要
塔里木盆地目前已发现39个油气田，其中大中型油气田21个，特别是塔河大油田和克拉2大气田的发现，进一步证明塔里木盆地油气前景十分广阔，油气田（藏）纵向分布具多时代、多层段复合叠加的特点；油气藏类型丰富多彩，可分为3大类、8个亚类、14种类型；具成藏期多（早海西期、晚海西期、印支-喜山期）、成藏（田）模式多样的特点；油气田空间分布主要受古克拉通盆地和中新生代前陆盆地及构造体系控制。上述特征对当前和今后油气勘探有重要指导作用。
39 oil fields have been discovered presently in the Tarim Basin.21 of them are large-to medium-sized,including giant Tahe oil field and Kela No. 2 gas field, which indicated a very bright future for hydrocarbon exploration and development in the basin. Distribution of oil and gas pools was characterized by stacking of multiple horizons And nds can be classified into different level of types which were formed in several pool-forming periods (Early and Late Hercynian, Indosinian - Himalayan) and showed various patterns of formtion. Distribution of oil fields was controlled by paleocraton basin, the Meso-Cenozoic foreland basins and structural systems. There is useful indication for hydrocation exploration in the basin in the study.
