Analysis of Influencing Factors to Working Capacity of L Gas Storage
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.
