Abstract: Geological conditions are favorable for hydrocarbon accumulation in the Kongquehe area where exists a composite petroleum system with the Cambrian to Ordovician marine sediments and Jurassic continental sediments as effective source rocks. The Paleozoic and Cenozoic are two main exploratory targets. Faulted anticlines are the main structural trap types in Cenozoic while faulted anticlinal, structural lithological and unconformity traps that have developed in large nose-like uplift settings are the main trap types in Paleozoic. Faults that control vertical migration of hydrocarbon are well developed and traps and sources match effectively both in time and space. The weak structural deformation during the late Yanshan and Himalayan periods is favorable for preservation of reservoirs. There are three types of plays in this area with large exploration potentials.
