摘要 为了对薄层深感应电阻率进行有效的校正,本文利用岩心实验分析资料并结合测井曲线特征,分别建立了深感应电阻率的岩性和层厚校正模型,以校正岩性以及层厚对薄层测井响应造成的影响,通过校正后的效果对比表明,计算的含水饱和度与岩心分析的饱和度非常接近,表明在研究区本文所用方法对薄层电阻率校正的实际效果很好,具有可行性和实用性。 In order to correct the value of deep induction resistivity effectively in the thin bed,this article gives a model to correct the thickness and lithology influence of deep induction resisitivity logging based on the well core analysis and the feature of logging curves.To compare the effect which before the correction and after the correction,the results indicated that the water saturation we calculated after the corrected is approach nearer to water saturation which derived from well core data.The method we used in the article is very effective,feasible and practical in the thin bed logging interpretation and evaluation.
