Abstract:Based on comprehensive analyses of data from field work, coring, well-logging and geophysical exploration, the wave processes in the Tabei area of the Tarim basin have been studied with the wave analysis method, in which a set of mathematical and physical principles are used. It is shown that 740-760 Ma, 200 - 240 Ma, 100 - 110 Ma, 60 - 70 Ma and 30 Ma are the main cycles which control the evolution of the Tabei uplift. The periods of the early Paleozoic, the Tri-assic and from the Tertiary to the present are the three main periods of depositional processes, and the end of the Silurian to the early Late Devonian is the main erosional period with the average hiatus over 1000 m, greater than 1500 - 2000 m in the northern part. Erosional processes are also obvious in the Hercynian, Indosinian and Yanshanian epoches. The buried depth of the top of the lower Ordovician at the end of the Silurian exceeds 2000 m, the bottom of the lower Ordovician is about 3300 m at depth. The deposition-erosion processes play an important role in the reservoir formation. The palaeotemperature measurement proves that the Cambrian and lower Ordovician source beds began to get matured by the end of the Ordovician and maintained the ability of secondary generation of hydrocarbons because of the uplifting. Because of the highspeed deposition and great burial depth during the Triassic, the burial depth of the top of lower Ordovician surpassed the original depth, and the lower Ordovician began to generate hydrocarbons in large quantity, and at the same time the Permian source bed also reached the threshold depth of massive hydrocarbon generation according to the burial depth calculation, but a series of uplifting occurred until late Tertiary, then the remains of the Permian surpassed the maximum burial depth of the early Paleozoic and Triassic, and the lower to middle parts of the Tertiary began to get matured. Therefore, the areas where the uplifting was of a large magnitude in the late Early Palaeozoic are favourable areas for secondary generation of hydrocarbon.
