摘要
随着国内天然气消费量逐年增加,预计到2020年我国天然气需求量将达到3500×108m3。建设地下储气库是保障天然气下游用户供气的调峰的重要手段之一,它具有储存量大、经济合理、安全系数高等优点。因此储气库的建设十分重要。本文主要介绍了中国建设储气库的必要性以及枯竭油气藏储气库选址、钻完井、固井方面面临的挑战和解决途径。
The domestic consumption of natural gas increasing annually ,it is expected that by 2020 China＇s natural gas demand will reach 3 500 x 10s m3. Construction of underground gas storage is one of the important means to protect downstream users from gas shortage during the peaking time ,which has the advantage of large storage capacity, economic rationality and high safety factor. Therefore, the construction of gas storage is significant. This article mainly introduces the necessity of China＇s construction of a gas storage and the gas storage locating and also challenges and solutions during the welldrilling , completion and cementing processes of depletion oil and gas reservoirs.
