The results by computing different plate width models show that magnetic field concentrate around the magnetizing system, and local region of a steel plate even with infinite large area can also been magnetized to saturation. 罐底板漏磁检测的三维有限元模型的计算结果表明,钢板内磁场主要集中在励磁装置的附近区域,并验证了在一定厚度下,即使无穷大面积的钢板也可能被局部磁化饱和;
This paper studies the interpretation method of this area in respect of core observation, gas logging, rock pyrolysis, fluorescent micro-image and interpretation plate, and discusses the application of apparent oil saturation method with a good effect. 本文从岩心观察、气测录井、岩石热解、荧光显微图像以及解释图版等多方面对该区的解释方法进行了研究,并探讨了视含油饱和度方法的应用,取得了较好效果。
