微球聚焦测井仪非均质k值的研究

On K Value of MSFL TOOl for Heterogeneous Media.

王芸，吴信宝．微球聚焦测井仪非均质ｋ值的研究．测井技术，１９９４，１８（１）：２２～２５本文阐述了微球形聚焦测井仪非均质仪器常数（ｋ值）的物理及数学意义，并对均质ｋ值和非均质ｋ值进行了对比，说明它们各自的优、缺点。通过大量的计算机考察．发现斯仑贝谢公司所给的ｋ值是非均质ｋ值，且并非适用于所有地层情况。本文根据我国油田地质情况，给出了几大油田的最佳非均质ｋ值。

alue of Micro-Spherically Focused Logging Tool in heterogeneous media and itsphysical and mathematical meaning are presented in this paper. By comparing the K valuesin homogeneous and heterogeneous media, the advantages and shortcomings of using the twoconstants in actual log are analysed. Through large quantities of numerical calculations wefind out the K value given by Schlumberger is the K value for heterogeneous media, whichis only good for some formation. According to the specific geological conditions of variousoil fields in China.the optimum K values are given respectively for the heterogeneous mediain several big oil fields and the application range of MSFL tool is thus extended in China.
