The trinomial deliverability equation can be determined based on the data of bottomhole flow pressure and gas production by using the rate multipleregression, and the open flow capacity and static formation pressure can also be derived.
为此,提出了一种精度高且计算简便的方法,不需要已知地层静压,只通过井底流压与产气量数据,利用多元线性回归方法,既可确定气井三项式产能方程,还可求得气井绝对无阻流量和地层静压。

Cultivated land quality was assessed by BP neural network in Dazu County, Chongqing. The assessment results showed that paddy lands were mainly of the second-grade and third-grade, while dry lands were mainly of the first-grade and second-grade. It illustrated the high natural quality of the cultivated land, but the natural quality only reflected land natural characteristics. Therefore, influence coefficient was used to modify natural quality index based on the investigation to households. At the same time, by using the household income as the value of cultivated land, the impact of natural quality and investment structure on the value were further discussed. The results showed that trinomial equation and binomial equation were fitted to reflect the relationship between natural quality and income.
该文采用BP神经网络模型对重庆市大足县耕地自然质量进行评价,发现研究区水田自然质量等级以二等地和三等地为主,旱地以一等地和二等地为主,耕地自然质量总体偏高;但耕地自然质量仅仅是耕地自然属性的反映,因此在基于对研究区农户行为调查的基础上,采用"影响力系数"对耕地自然质量进行修正,并将农户收益作为耕地质量货币化价值的表现,进一步讨论了耕地自然质量和农户投资结构对这种价值的影响以反映对耕地质量的影响。
