| 摘 要： | 根据多孔介质渗流力学理论研究了斯仑贝谢公司的重复式电缆地层测试器测试曲线的解释理论。由扩散方程解出了球形流动与柱形流动的压力分布,确定了三种条件下的解。根据试井分析的叠加原理,导出了多种流量条件下球形与柱形流动的计算渗透率的公式与流动函数,并且讨论了使用这些公式的条件。同时,还从理论上找到了斯仑贝谢公司所给公式的来源,并为进一步开展电缆地层测试器的解释方法的研究建立了基础。

| Abstract: | The log interpretation theory of Schlumberger RFT has been studied according to the seepage flow me-chanics of porous media. The pressure distribution of spherical and cylindrical flow is derived from the diffu-sion equation, and solutions under three conditions are given. The permeability formula and flow functionsfor spherical and cylindrical flow under multi-flow conditions are also obtained from the superimposure theo-ry used for well test analysis. How Schlumberger's formula are derived is found out in theory, thus, pro-viding the basis for further study of RFT log interpretation. |
