摘要
页岩气井单井产能生产初期递减较快,随着累计产量的增加递减趋势变缓,呈对数趋势递减。页岩气井单井初期产能主要根据经验一点法求取,利用四川气田经验配产法进行配产,由于页岩气井产能的动态变化特征,需要及时调整配产系数。页岩气井动态产能主要通过回压试井进行评价,再通过采气指示曲线法确定合理的配产系数,同时通过分区间拟合产能随累计产量变化趋势关系,建立产能变化图板,用于指导页岩气井生产。
Single well production capacity of shale gas wells decreases quickly at initial production stage but slowly with increase of cumulative production as logarithmic trend. It is acquired mainly by empirical one-point method and optimal production rate is based on empirical production method from Sichuan Gasfield. Production rate needs adjusting timely according to dynamic capacity change features of shale gas wells. Dynamic capacity is evaluated mainly through back pressure test. Optimal production rate is determined by gas production indicating curve and at the same time capacity variation chart is established according to trend relation that inter-partition matching capacity changes with cumulative production to guide shale gas well production.
