摘要
本文利用镜像反映原理和叠加原理,导出了在调查范围内,地层存在非平行的两条不渗透直线边界或一条不渗透直线边界,一条定压直线边界的距离计算公式。边界距离并非都可用0.75 ηt<sub>g</sub><sup>1/2</sup>来计算,它与边界夹角、边界性质、井点位置有关。
From the principal of reflection and superposition, this paper has derived a calculation equation for two lines of nonparallel nonpermeable linear boundaries existed in the formation in the scope of investigation, or a non-permeable linear boundary and a steady pressure linear boundary distance. The boundary distance is not always calculated with 0.75 (ηtg)(1/2), it is also related to boundary included angle, character of boundary and the position of well points.
