摘要
作者通过积分变换求解一类三维扩散方程，提出了评价油气井钻井过程中地层伤害程度的定量描述方法，研制了一个性能较全的计算机软件系统，通过实例检验，证明了本方法的有效性。文内给出了水平井地层伤害程度定量评价参数——表皮系数的计算模式，介绍了水平井地层伤害定量评价计算机系统ＳＦ－ＤＡＨＷＤ的主要功能与总体结构。
A new quantitive method for desribing the formation damage during horzontal wells drilling was presented. Acomprehensively practical computer System was developed. This method introduced here was tested by a practical example from oilfield. This is the application part. The important evaluation parameter for the horizontal formation damage——skin factor was obtained through establishment its mathematical model. Acomputer sustem for the horizontal wells formation damage evaluation was developed. The general functions and structure of the computer system SFDAHWD were introduced. A practical application example was given.
