摘　　要：阐明核磁共振测井 (NMR)在储层评价中的作用 .利用NMR测井资料对桩海地区长堤油田的储层特性及产能、复杂岩性储层的孔隙度作出评价 ,并在电阻率测井资料显示不好的复杂储层条件下进行油气水层识别 ,以及指导完井和钻井方案的实施等 .还阐明了核磁共振测井技术具有常规测井技术所不具备的特点 ,特别是定量的评价孔隙流体流动特性、准确划分产层、直接识别油气水等优点 ,从而有利于解决复杂的地质问题 .The paper focuses on the application of the nuclear magnetic resonance technique on the well logging, which is one of the new techniques applied on the well logging in the oil fields, and throws light on the vital role of nuclear magnetic resonance (NMR) in appraising the reservoir beds. Using the well-log information of NMR, the authors have evaluated the reservoir properties and productive capacity of Changti Oilfield in the Zhuanghai area and the reservoir porosity of complex lithology, told apart the hydrocarbon zones in the complex reservoir conditions which are dully revealed from the data of the resistivity well logging and also made an instruction of bringing the programme of the well completion and well-drilling into practice. The nuclear magnetic resonance is a practical and up-and-coming logging technology and has a special and large potential application which is not available for the conventional log technique, especially in the quantitative evaluation of pore flow behavior, the exact output division and the right identification of oil-gas and water. Therefore, it can smooth over many complicated geological problems.
