Abstract: Shenquan oilfield is a typical composite oilfield in Turpan-Hami basin, containing Jurassic, Cretaceous,Tertiary (upper,middle and lower part) reservoirs in vertical,and twelve oil-bearing fault blocks developed in plane.Each block has an oil-water systern of its own with different oil/ gas enriched degrees. Since implementation of rollingexploration and development schemes in 1996, eight new petroliferous fault blocks like Shen-213, Shen-220, etc. havenot only been found, but Upper and Middle Tertiary reservoirs have been discovered, with results of increase in reservesamount year by year,and productivity added from 1x10' t to 11x10' t. Hence,to review the petroleum accumulationcharacteristics,their major controlling factors and technical route, policy and operation mode of the rolling explorationand development possess practical and useful significance.
