Abstract:The technologies of natural gas flooding are reviewed in this paper. The natural gas flooding is mostly applied in America, Canada and the former Soviet Union. Typical projects are described. The causes of slow development of the natural gas flooding in China are analyzed. The natural gas flooding projects in Changqing oil field and the Daqing oil field are taken as samples in China. The oil reservoir conditions, the well net, the well spacing, the injecting conditions and the injecting modes in the natural gas flooding peojects are analyzed. The problems and their solutions during the natural gas flooding operation are discussed.
