| 摘 要： | 本文提出一种混合波模型,用电偶极子和磁偶极子等效裂缝天线,兼顾了以往各种理论模型的优点.对胜利油田的电磁波测井（EPT）资料,分别用混合波模型和平面波模型求解得到的介电常数代入各种解释模型,计算储层的含水饱和度,再与实际岩芯测量建立的关系相比较,证明混合波理论模型更合理,解释结果更接近实际.

| Abstract: | This paper presents a mixed wave model which is equated to the sloted antenna with a electric dipole and a magnetic dipole. This model have an advantage over formerly models. EPT logs of Sheng-li oil field have been processed by means of the mixed wave model. Dielectric constants computed using the mixed wave and plane wave model are used to compute reservoir formation water saturation with general interpretation equation. The results of logging interpretation are compared with model derived from the measurement of actual cores. It is shown that the mixed wave model is more available than other models. The result from logging interpretation arc in good agreement with actual information. |
