Abstract : yanchang series is a typical low permeability reservoir, and its favourable sandstone reservoir is delta facies. heavy compaction, cementation and heterogeneity exist in it. according to the analysis of the main control factors of forming the secondary pore, it is held that the secondary pore in longdong area is controlled by both favorable facies belt and abnormal formation pressure. it is also held that the formation of the abnormal formation pressure is due to the dewatering of the clay mineral during diagenesis because the dewatering time is identical with the decarboxylation time of organism. organic acid and co2 are driven to adjacent favorable reservoirs under the abnormal formation pressure, and a lot of secondary pore is produced in the runners. from the present exploration result, it is useful to predicting the development of secondary pore to study the distribution of abnormal formation pressure
