TRAPPING CHARACTERISTICS AND ACCUMULATION RULES OF HYDROCARBON IN THE SHAYA UPLIFT OF THE TARIM BASIN

The Shaya Uplift in the Tarim Basin is an important tectonic zone for hydrocarbon reservoir development. Based on the reinterpretation of seismic profiles and compilation maps which have already been obtained in the strdy area,the hydrocarbon traps in this area can be classified into three types and ten subtypes. These traps of different stages and different types usually superimpose and intersect longitudinally,and exist in rows and in belts planarly. Starting with the major factors controlling hydrocarbon accumulation and its assemblages,the hydrocarbon accumulation characteristics are discussed in this paper. This has certain directive significance to further hydrocarbon exploration in this area.
