The Wu 420 C6 reservoir of Jiyuan oil field belongs to low porosity and ultra-low permeability reservoir, of which main layer is Chang6-1. In recent years, along with water flooding development, there have been many problems, such as plugging of formation, water absorbing inequality, well production decline faster. This paper, considering two aspects of geology and oil development, analyzed some influence factors during water flooding development in Jiyuan oil field. It will be instructive for developing low-permeability oilfield efficiently.
