Bedding fractures are well developed in tight sandstone, and the existence of bedding fractures has a very important influence on the formation and distribution of tight sandstone oil and gas reservoirs. However, there are few researches on bedding fractures at present. In this paper, the definition of bedding fractures is redefined and the recognition of bedding fractures is compared. The occurrence characteristics of bedding fractures and their influence on oil and gas distribution were preliminarily studied through outcrop observation, core description and microscopic observation. The results show that bedding fractures are generally developed in high energy hydrodynamic environments such as river channel, sea (lake) bank and beach, which parallel bedding is the main type of bedding fracture development. The bedding fractures along the dark streaks between the sandstone laminae, and the cracks generally crack along the cleavage plane of biotite. The existence of dark minerals results in weak laminar adhesion. Beddings lead to weaken the bond force of laminae because of the existing of dark minerals. The hole development condition of bedding fractures is better than that of the upper and lower sandstone laminae, and the occurrence of bedding fractures changes the physical properties of the original tight sandstone, the reservoir permeability with well-developed bedding fractures is 3.01~18.95 times of that with undeveloped fractures. Influenced by these, bedding fractures become an important channel for hydrocarbon migration, macroscopic bedding fractures control the lateral migration of oil and gas between sand bodies in tight sandstone oil and gas reservoirs; microstratigraphic bedding fractures and structural fractures control the migration and distribution of oil and gas in the single sand body together. The research results are of great significance for strengthening the late studies of tight gas sand bedding fracture, improving the success rate of prediction of “sweet point zone” in tight sandstone oil and gas reservoirs, and increasing the success rate of tight sandstone oil and gas reservoirs exploration. <摘要译文>
