Abstract: In this paper, integration of the basic principles of geology and tectonics, comprehensively used of seismic, well logging, logging, core and production testing to study relationship between the development rules the Tenan depression bedrock buried hill and hydrocarbon distribution. Through the study of target bedrock buried hill oil and gas reservoir characteristics, to explore the law of bedrock buried hill development, and provide exploration value of exploration targets. Using numerical simulation methods, combined with a large number of facts, this paper has been studied the relationship of the law of Tenan depression bedrock buried hill development and hydrocarbon distribution. The results show that: type of bedrock buried hill reservoir space in Tenan depression is mainly construct seam. The Tenan depression related to fold—related fracture developed area is widely distributed, and related to fracture cracks developed area is distributed of smaller. Fault system in the bedrock buried hill is good for hydrocarbon accumulation, and the closer away from the fracture, the crack is more development. Predicted a favorable exploration area, mainly near the Te19-29 well and Te19-66 well.
