摘要
气井单井经验数求解方法是一点法试井的关键。对现有的一点法试井资料处理方法进行总结发现,现有气田经验数均取之大量井的经验数值的平均值,单井经验数的求取方法,总体可以分为2类:(1)结合产能试井的方法;(2)结合不稳定试井的方法。对一点法的单井经验数的求取方法进行对比评价,发现与产能试井相结合的方法可以获得特殊气藏单井的经验数,并且数据的处理方法简单,而与不稳定试井相结合的方法只能用于常规产能方程的经验数的求取,数据的处理较复杂。建议在一点法评价产能时,最好使用与产能试井相结合的方法。
The key of single-point well test in gas well is how to get experience coefficient α accurately using well test data.On the basis of previous studies,this paper points out that available methods for getting this α are based on statistical experience values from many gas wells,and then averaging them for it.But for a single well,it is comprehensively got by two kinds of methods,the first kind is based on productivity well test data,the second one is based on pressure transient testing data.The comparison and evaluation of them show that the former is more suitable for special gas reservoir single well's α and relatively simple for the data processing,the latter is only suitable for getting α by conventional productivity equations,and the data processing is more complicated.So the first kind is recommended to be applied for it.
