摘要
本文对平均温度平均压缩系数法(以下简称TZ)计算气井井底压力的方法进行了改进,提出了用加权温度加权压缩系数计算气井井底压力的方法,并用最优化方法计算出了权重值。不管是动气柱还是静气柱,用本文改进方法计算的结果与公认的Cullender-Smith方法计算的结果具有同等精度。
This paper improves the method of calculating gas well bottom pressure by using average temperature and average compression coefficient (latterly called for short as■ method), pre-sents a method to calculate it by useing the method of weighted temperature and weighted com-pression coefficient and calculates the weighted value by using optimum method. For the both of dynamic and static gas column, the calculating result by the improved method in this paper has an equivalent precision with that by the generally recognized Cullender-Smith method.
