摘要
理论上分析了指数式产能方程产生偏差的原因。矿场产能试井实例分析表明,当测点压差大时,二项式产能方程与指数式产能方程计算结果偏差不大;但当测点压差小时,指数式产能方程产生较大的偏差。气井二项式与指数式产能方程偏差分析为矿场正确应用产能方程提供了理论依据。
The reason of bias for using the exponential deliverability equation is analyzed.The analysis of well testing for producing-power in field indicated that the drifting between the binomial and exponential equation is small as the pressure difference of the measuring point is small,but the small pressure difference brought on the high bias in exponential equation.So,using the variance analysis between the binomial and exponential equation of producing-power provides a theoretical basis for using deliverability equation correctly in field.
