Abstract: In view of the shallow burial, high viscosity, and strong heterogeneity of crude oil in shallow super-heavy oil reservoir in Fengcheng Oilfield, there are many challenges in the SAGD development of dual-horizontal wells. This paper aims to study SAGD development technology and supporting technologies of shallow super-heavy oil reservoir, optimize the deployment design of double horizontal wells, design SAGD cycle preheating and reservoir project, and study supporting key technologies such as drilling and completion technologies, downhole string structure, and downhole temperature and pressure measurement. According to development practice and technical and economic indicators, the technical limits of SAGD development for super-heavy oil dual-horizontal wells were formulated, and new technologies to improve SAGD development effects were comprehensively discussed, including composite well pattern development, reservoir expansion and stimulation, and solvent-assisted SAGD. The supporting technologies for shallow SAGD series development provide an important reference for the development of similar gas reservoirs.
