核磁共振成像测井资料在杭锦旗区块气水层测井识别中的应用

杭锦旗区块上古生界储层非均质性强，岩性变化快，气水关系复杂，储层流体性质识别困难，而储层流体性质识别是测井储层评价的核心内容，本文利用地质、测井和实验分析等资料，依托核磁共振成像测井能识别地层中不同大小的孔隙，同时还可以不依赖于电阻率就直接识别地层中气水的类型，提出常规测井资料结合核磁共振成像测井资料的流体性质综合识别方法，解决了常规测井方法在解释储层物性、孔隙结构和气水层识别中的难题，更好地为气田的勘探开发服务。

The Application of Nuclear Magnetic Resonance Imaging Logging Data to Gas Water Layer Recognition in Hangjinqi Area

Upper Paleozoic reservoir of Hangjinqi area has strong heterogeneity, rapid li- thology changes, and complicated gas water relationship. The recognition of reservoir fluid property is difficult, but the recognition of reservoir fluid property is the core of logging reservoir evaluation. Based on geological, well logging and laboratory analysis data, nucle- ar magnetic resonance imaging logging is used to recognize the hole in different sizes. Meanwhile, gas water type can be directly recognized which does not depend on fluid resis- tivity. The comprehensive identification method is proposed, which is the combination of conventional logging data with nuclear magnetic resonance imaging. The problems, such as reservoir physical properties, pore structure and gas water recognition, can be better solved, which can be helpful for the gas field exploration and development.
