摘　　要：储气库在我国天然气季节调峰中发挥越来越重要的作用,受地质体以及注采制度制约,油气藏型储气库无法发挥最大产能。以L储气库为例分析制约油气藏型储气库产能的因素,并给出最优的采气速度值,为达容达产提供依据。通过分析认为,地质敏感性是制约储气库采气的主要因素,在分析层间干扰、应力敏感性以及产能方程的基础上,得出L储气库平均单井采气量为10×10~4~20×10~4 m~3/d时可以发挥储气库最大产能,除此之外,合理的注采制度以及开关井顺序也是影响储气库产能的重要因素。Gas storage plays a more and more important role in seasonal peak regulation of natural gas in China.Due to the restriction of geological body and injection-production system,gas storage of oil and gas reservoir can not exert its maximum production capacity.Taking L gas storage as an example,the factors restricting the production capacity of oil-gas reservoir type gas storage are analyzed,and the optimal gas production rate is given to provide the basis for the capacity to achieve production.Based on the analysis of interlayer interference,stress sensitivity and productivity equation,it is concluded that the maximum production capacity of L gas reservoir can be achieved when the average gas production per well is 10×104~20×104 m3/d.In addition,Reasonable injection-production system and switching well sequence are also important factors affecting gas storage capacity.
