序言半个世纪以来,对于机井(管井)滤水管的设汁,许多学者根据自己试验和对生产井的观察,提出了不同的计算机井最大允许滤水流速的公式,在不同国家和地区,也得到了较长时间的采用。但因差别较大,在生产中采用时多有不便。为此作者追溯了各家公式的来源,并作了初步的分析辩证。发现 Preface Since half a century, many scholars have put forward different formulas for calculating the maximum permissible flow rate of water in computer wells according to their own experiments and observation of production wells. In different countries and regions, many scholars also Got a longer time to adopt. However, due to the large differences in the production of more inconvenience. For this reason, the author traced the origin of each formula, and made a preliminary analysis of dialectical. Find
