Suqiao Reservoir Development and Storage Design

Abstract

This chapter introduces the exploration and development of the Suqiao reservoir, as well as the design for rebuilding the gas storage facility after reservoir depletion and the operation of the gas storage facility. The Suqiao storage group, with a burial depth of close to 5000 m, consists of five reservoirs: the Su1, Su4, Su49, Su20, and Guxinzhuang reservoirs. In the process of building the storage group, we made full use of the trap dynamic sealing property evaluation technology under complex geological conditions, the partitioning evaluation technology of the storage capacity parameters, the optimization operation technology of the injection and production of fractured, sandstone reservoirs, the drilling and completion technology of super-deep, low-pressure reservoirs, and the reservoir protection technology to optimize the geological scheme and the engineering scheme design. The storage facility was put into operation in 2012, and since then, it has been playing an important role in peak load regulation and supply guarantee in Beijing, Tianjin, and Hebei.
