核磁共振录井技术在辽河油田的初步应用

从核磁共振录井技术的优势分析入手，简介了该技术方法的原理和T2弛豫谱约意义；对应用该技术的测量精度进行了分析对比，依据辽河油田的储集层特点，初步制定了核磁共振录井解释标准。重点介绍了该技术在辽河油田的初步应用情况，从已完成的20余口井试用情况看，解释结论与试采结果对比，解释符合率为86．1％。认为该技术测量精度达到了现场解释评价的要求，精度高，分析快速，解释结论准确可靠，可以为完钻讨论、确定试采层位、实施措施等提供实时、准确的数据参考依据。

Initial application of NMR mud logging technology in Liaohe Oilfield

Starting with analyzing the superiorities of NMR mud logging technology, the paper briefly introduced its principle and significance of t_2 relaxation spectrum, made analysis and correlation of its applied measurement precision, and according to reservoir features of Liaohe Oilfield, initially set up the interpretation criteria for NMR mud logging. It mainly introduced the initial application state of the above technology in Liaohe Oilfield. Viewing from trial employment situation from over 20 completed wells and contrasting interpretation conclusions with producing test results, the interpretation coincidence rate was 86.1 per cent, therefore the measuring accuracy of this technology had met the needs of on-site interpretation and evaluation, it had the characteristics of high accuracy, rapid analytical speed and accurate and reliable interpretation conclusions, and could provide real-time, accurate data reference for finishing drilling discussion, determining producing horizons and implementing measures etc.
