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。
NMR imaging logging technology is an excellent open-hole logging method based on NMR. By measuring the hydrogen nuclei in the voids, it can not only provide accurate porosity, but also can analyze and classify the voids, obtain effective porosity, and then estimate the permeability and other useful information. At the same time, different fluids can be utilized to analyze and identify the fluids in the interspaces with different relaxation characteristics. It can provide much more formation information than any other single well logging method, especially complex lithology and special lithology, low resistivity reservoir, which is one of the commonly used and effective methods.
