TECTONIC DEFORMATION OF YAKERLA-LUNTAI REGION IN NORTH TARIM BASIN AND ITS CONTROL ON OIL/GAS ACCUMULATION

In the present paper, the tectonic deformations of the Yakela-Luntai region of North Tarim basin and their evolution have been detailedly described. It is considered that the most important factors controlling oil/gas accumulation comprise long sustained uplifting, repeated faulting, presence of unconformities,favourable structural style etc. A combination of palaeouplifts,large faults and stratigraphic unconformities seems necessary for the formation of economic oil pools. Also the structural trap of oil in the region are discussed at great length and some target spots for subsequent exploration are proposed.
