| 依据电阻率测井资料计算含水饱和度主要是通过建立地层电阻率与地层含水饱和度之间的关系--饱和度模型来实现,当前采用的饱和度模型大多数属于经验模型,例如阿尔奇公式、Waxman-Smits模型和双水模型等,而有效介质理论是基于电阻率测井求取含水饱和度的一种理论模型,避免了现有经验方程的局限性,有望成为现有经验模型计算含水饱和度的有益补充。文章给出了有效介质的基本理论,并归纳总结了基于有效介质理论的泥质砂岩电阻率模型--有效介质非对称电阻率模型(HB方程)和有效介质对称电阻率模型(SATORI方程),对它们的假设条件、适用范围、局限性和应用现状进行了讨论分析。最后对有效介质电阻率模型的发展趋势给出了建议。 |
| 英文摘要: |
| The calculation of water saturation with the resistivity logging data is performed to build saturation models which describe the relationship between the resistivity and the water saturation of strata. Most of the saturation models belong to empirical models such as Archie equation, Waxman-Smits model and Dual water model etc., but the effective medium theory is a theoretical model that calculates the water saturation based on resistivity logging, this model can avoid the limitation of the existing empirical models and could be expected to become the beneficial supplement to the existing empirical models on calculating the water saturation. This paper introduces the basic theory of the effective medium, and summarizes the resistivity models for shaly sandstone based on the effective medium theory, namely the non-symmetrical effective medium resistivity model (HB equation) and symmetrical effective medium resistivity model (SATORI equation), then analyzes the assumptions, application scope, limitations and application status of the two models, and finally proposes the suggestion on the development trend of the effective medium resistivity model. |
