摘要：

根据承压不完整(竖)井井壁出流量估算所采用的吉林斯基与马斯克特配用公式与计算现实的不适应性,利用配用公式提供的有用“边界”信息进行统计分析,以垂向出流变化为特征,建立了分区代数方程边值问题的提法和求解。所得解案保留了配用公式的主要性态,实现了出流量向超大口径和小相对滤器长度范围的双重开拓目的。它既反映出流量于小相对滤器长度范围的堆积、均化过程,又找出了超大口径井的极限出流量,经与日本库什尼同类公式相比,具有明显的优点。

In view of the unsuitability of Gelinsky's and Maskut's formulas for practical calculation,which are generally used to estimate the wall discharge of non-integral vertical wells under pressure,statistical analyses were conducted by using the useful“boundary”information provided in the above formulas and the issue of boundary values for zoning algebraic equations and their solutions,characterized by the change of vertical discharge,are presented in the paper The presented solutions retain the main characteristics of the afore-mentioned formulas and bring about develop- ment of discharge in very large diameter and within the length of minor relative filter.The solutions have not only reflected the process of accumulation and averaging of the discharge within the length of the minor relative filters,but also given the ultimate discharge of very large diameter well.The solutions have a remarkable advantage over the sim- ilar fomula by Kyzeny,Japan.
