Zhanazhol is a weakly volatile reservoir of fractured pore carbonate. The reservoir has poor physical properties and strong heterogeneity. During injection development, the pressure of injection wells is severe and the effect of water injection is not obvious. Making full use of abundant associated gas resources for gas injection development is the best way to stabilize and restore formation pressure and improve oilfield development effectiveness. In order to clarify the impact of different geological characteristics and development parameters on the gas injection development effect of fractured pore carbonate reservoirs, an orthogonal test method was used to analyze the main influencing factors of gas injection development. Studies have shown that the order of the influence of various parameters on gas injection development from high to low is injection-production ratio, well spacing, oil production rate, gas injection timing, matrix permeability, formation dip angle, fracture volume density, net pay thickness, ratio of horizontal permeability to vertical permeability. The research results provide support for formulating gas injection development technology policies and improving oilfield development effect.
