摘要
核磁成像测井技术是一种以核磁共振为基础的卓越的裸眼井测井方法。通过测量空隙中的氢核它既不仅可以提供精确的孔隙度,而且可以对孔隙进行分析分类,得到有效孔隙度,进而估算渗透率等有用信息。同时还可以利用不同流体有不同弛豫的特性准确的对空隙中的流体进行分析,识别。相比于其他任何单项测井方法,它所能提供的地层信息要丰富的多,尤其是复杂岩性和特殊岩性,低电阻油藏,它是常用的有效方法之一。
The magnetic imaging logging technology is an excellent open hole logging method based on magnetic resonance.By measuring the proton in the formation,it can provide not only accurate porosity,but also the important information such as classified analysis about the pore,effective porosity and permeability,etc.Meanwhile since different fluids have different relexation,it can identify the formation fluids.It can provide more information than other logging methods,especially for complex lithology,particular lithology and low resistance reservoirs.
