Reservoir characteristics and the potential evaluation in Liaohe Qijia buried hill

Based on the core, log and seismic data, this paper carried on a compreshensive study on Qijia buried hill reservoir lithology and physical properties.analyzed the buried hill reservoir condisitions tectonic movement, migration pathway, reservoir-cap allocation. Intense tectonic movement controlled the buried hill evolution provided a good place to hydrocarbon reservoir; faults and unconformities provided conditions for the oil and gas migration; trap and migration of the relationship between space-time configuration determined whether the oil and gas can be accumulated; good cover layer to buried hill trap accumulation. In this paper it's thought that Qijia buried hill belonged to a flip-style accumulation model, and predicted a favorable area for the buried hill oil and gas traps is in the ancient Qigu 6 and Qi 2-12- 14 Well, which provided guidance to the further exploration.
