塔里木盆地天然气资源及勘探方向

THE RESOURCE AND EXPLORATION OF NATURAL GAS IN TARIM BASIN

塔里木盆地发育3套优质气源岩,具备充足的气源条件。由于塔里木盆地各构造单元的勘探程度不同,近年来又取得了许多新的勘探成果,因此,采用新思路、新方法、新概念重新对塔里木盆地进行了新一轮油气资源评价。最新评价结果是塔里木盆地油气总资源量为123.37亿t油当量,其中油资源量为59.94亿t,天然气资源量为79599.43亿m3。目前全盆地天然气探明度很低,勘探潜力巨大。研究结果显示,库车坳陷是近期天然气勘探的主战场,塔西南坳陷是天然气勘探的接替区,塔东地区是天然气勘探的准备区。

There are three sets of high quality gas source rocks in Tarim Basin, So that it is abundant in generating gas. As the different exploration extent of each structural unit in Trim Basin, and recently there are much of exploration accomplishment, it is largely necessary to assess the oil and gas resource quantity of tarim basin renewal in case of adopting the new idea, new method and adequately considering the recovery and economic efficiency of resources. The latest result of oil and gas resource assessment is that the total resource is 123.37 million tons equivalent, which oil is 59.94 million tons and gas is (79 599.43) million cubes. The gas proved extent of Tarim is so primarily recently that its exploration potential is much more immense. The finding research shows that kuche depression is main exploration zone recently; Taxinan depression is the next exploration zone, and Tadong depression is exploration zone later.
