The controlling factors of Chang 8 reservoir in Pengyang area are unknown, which affect the progress of exploration and development in Pengyang area. In view of this situation, combined with seismic profile data, the oil source, reservoir characteristics and main controlling factors of reservoir formation are comprehensively analyzed by means of thin section, phase permeability, fluid inclusion and other methods, The reservoir is mainly controlled by structure and lithology, and partially controlled by faults. Combined with the reservoir reconstruction such as self generated thermal fracturing, the productivity of single well is greatly improved, which can provide the basis for subsequent production, construction and development.
