应用沉积盆地波动过程分析方法对塔里木盆地塔北隆起、北部坳陷和中央隆起３０余口井所作研究结果表明，塔里木盆地自震旦纪以来经历了震旦纪、寒武纪—中泥盆世、晚泥盆世—侏罗纪和白垩纪—现今四个一级周期沉积波动的演化历程。它们持续的时间分别为２３０，２０３，２２１４，１４５６Ｍａ，其中白垩纪至今盆地演化过程大致经历了一个完整周期的３／４。每一个演化周期对应于一个大的盆地演化阶段，并对应于一个大的成藏旋回。
Based on the analysis of fluctuating processes in sedimentary basins, the study on more than 30 wells in Tabei uplift, northern depression and central uplift of Tarim Basin shows that the Tarim Basin experienced Sinian, Cambrian-Middle Devonian since Sinian, , Late Devonian - Jurassic and Cretaceous - Evolution of depositional fluctuations of four first - order cycles at present. They last 230, 203, 221.4 and 145.6 Ma, respectively. The evolution of the basin from the Cretaceous to the present has experienced about three-fourths of a complete cycle. Each evolutionary cycle corresponds to a large basin evolution stage and corresponds to a large cycle of hydrocarbon accumulation.
