摘要
针对常规录井、测井方法难以解决吐哈油田非均质低渗透储集层评价的问题,提出利用核磁共振录井随钻测量动态条件下的储集层束缚水饱和度,进而确定其相渗关系。在简介核磁共振录井技术原理和阐述其信息资料特征的基础上,给出了核磁共振录井与其他录井参数相结合判别储集层类型、识别储集层流体性质的初步油气层解释评价标准,通过实例对应用效果进行了分析;结合核磁共振录井的技术优势对核磁共振录井技术的发展方向进行了展望,认为核磁共振录井技术与其他技术结合是提高储集层解释评价符合率的重要手段之一。
In view of the problem that the heterogeneous and low permeability reservoir in Tuha Oilfield is difficult to be evaluated by conventional mud logging and wireline logging, the paper puts forward to use the reservoir bond water saturation under the condition of the nuclear magnetic resonance logging measurement while drilling to determine its phase permeability. On the basis of briefly introducing the principle and its information and data characteristics of the nuclear magnetic resonance logging technology, it gives out the initial oil and gas interpretation and evaluation standard for judging reservoir types, distinguishing reservoir fluid properties by combining the nuclear magnetic resonance logging with the other mud logging parameters, analyzes the application effect by practical examples, looks into the distance for the development direction by combining the technical advantages, and considers that combining the nuclear magnetic resonance logging technology with the other technologies is one of the important means for improving reservoir interpretation and evaluation coincidence rate.
