To the problems of the slope of the early period on log-log plot is more than 1 and the data of the middle period and late period is too discrete which makes the early period of theoretical curve can not be matched and too discrete middle and later data makes too difficult for interpreters to make acute analysis.
针对双对数图早期段斜率大于1,使理论曲线无法拟合;而中后期的压力导数数据太过离散,使得解释人员无法做出正确分析的问题,研究了用实测压力、温度资料计算天然气的PVT参数,应用计算的粘度和压缩系数对实测压力点进行校正,解决了早期段资料斜率增大的问题,使理论曲线能够较好地与之拟合;用积分变换对压力导数进行处理,解决了中后期资料离散化的问题。
