在对塔里木盆地累积及不同时期生油气量进行定量计算的基础上,指出塔里木盆地虽然累积生油量巨大,必定曾有过大规模的油气聚集,但由于主力成油期过早,使早期形成的巨一大型油藏容易受后期多次强烈构造运动的破坏、改造的影响,使油的富集规模和强度大为减小。因此,盆地内对石油的勘探应立足于寻找中、小型油田;虽然盆地内大部分气也生成于古生代,但相对于油而言,中新生代生成的气所占比例较大。这些生成期晚的天然气是盆地内气资源的主要来源,并使盆地内的气资源前景优于油资源。比较丰富的天然气资源及其较为集中的时代分布,使盆地内气的勘探前景看好。预期塔里本将成为一个富气盆地。
Based on the quantitative calculation of the accumulated and different periods of hydrocarbon generation in the Tarim Basin, it is pointed out that although the accumulated oil generation in the Tarim Basin is huge, there must have been large-scale hydrocarbon accumulation. However, due to the premature oil-formation period of the main force, The huge giant reservoirs are easily affected by the destruction and remolding of many intense tectonic movements in the late period, which greatly reduces the scale and intensity of oil enrichment. Therefore, oil exploration in the basin should be based on the search for medium-sized and small-sized oilfields. Although most of the gas in the basin was also generated in the Paleozoic, the amount of gas generated by the Mesozoic and Cenozoic accounts for a large proportion relative to oil. These late-generation natural gas is the main source of internal gas resources in the basin and outperforms the oil resources in the basin. The abundance of natural gas resources and their more concentrated distribution of the times make the prospects of gas exploration in the basin favorable. Tarifa is expected to become a gas-rich basin.
