摘要： 对于各向同性地层,采用均匀井距的井网即可达到均衡驱替的目的;而对于各向异性地层,不同方向上的井距必须根据渗透率大小进行适当的调整,方可达到均衡驱替。通过坐标变换法和流管法两种完全不同的方法,可以得到各向异性地层井距调整的理论公式:不同方向上的井距之比等于相同方向上的渗透率之比的平方根。

Abstract: Uniform displacement of isotropic reservoirs can be established by means of even well spacing or well pattern, but that of anisotropic reservoirs depends on proper regulation of well spacing of different directions by permeability contrasts. This paper presents the theoretical equations for the latter through coordinate transformation and streamtube approaches. The results show that the ratio of well spacings in different directions equals the square root of the ratio of permeability in corresponding directions.

Key words: well pattern, well spacing, reservoir, anisotropy, isotropy
