Abstract: The Sudeerte buriedhills are very important reservoirs in the Hailaer Basin. The best reservoirs are generally developed on top of the Triassic metamorphosed siliciclastic rocks called Budate Group and with a thickness from several tens to over 100 meters. The socalled bimedia pore spaces composed of pore and fractures are the prevailing reservoir types with mean porosity of 5.0% and permeability of 0.03×10-3μm2. Two genetic types of the buriedhills can be recognized, faulted block and weathered peleouplift. With southwards subduction of the MongoliaOkhotsk plate north of the studied area during Triassic to early Cretaceous, the Hailaer Basin suffered uplifting and weathering, secondary burying and block faulting, volcanism and fluid alteration, which constructed the buriedhill reservoirs there.
Key words: Hailaer Basin, Sudeerte area, clastic buriedhill traps, hydrocarbon reservoirs
