The Lukqun structural belt is located on the leading edge of the Kumu uplift, a favourable area for the hydrocarbon accumulation in the Tainan area, Turpan-Hami Basin, Xinjiang, where the heavy oil reservoirs occur as secondary oil reservoirs. The crude oil with low maturity was graded into the heavy oil due to the bleeding of light components during the hydrocarbon accumulation. The lacustrine mudstones have contributed to the steady hydrocarbon sources from the Permian Taodonggou Group in the Taibei depression. The highly developed faults and unconformities have provided good channels for the oil and gas migration and accumulation. The models for the accumulation of secondary heavy oil reservoirs proposed in this study may be significant to the future exploration of supergene light oil and gas, and deep-seated gas and condensate oil in the Turpan-Hami Basin.
