| 摘 要： | 本文提供一种从试井求得的平均渗透系数回算每个单层渗透系数的方法。井的试验,无论是为供水、排水或工程建设目的的常规试井,还是为热田开发目的的专门性地热试井,其首要任务是确定含水层或热储层的各项参数,其中最主要者为地层的渗透系数K。

| Abstract: | In this paper a novel method of polynominal regression analysis for information extraction of single-layer parameters from a mean permeability obtained by well-test is proposed. The parameters used in deriving information distribution equations are strata sequences, well structure and the final results of the well-test. General cases of symmetric or nonsymmetric uncompleted wells in a multi-layered horizontal aquifer are considered as the target models. The final solution is obtained by means of solving n simultaneous information distribution equations for extraction of hydrodynamical parameters for N single layers, while n >N. The method has been proved to be successful with reasonable results of single stratum permeabilities for the Yangbajing Geothermal Field, Xizang (Tibet), where n=7, N=5. |
