摘　　要：随着核磁共振测井技术在石油勘探中的广泛应用,在直井和小斜度井中进行核磁测井作业已很常见,但在水平井和大斜度井中进行核磁测井比较罕见,急需探索出一套完整的工程解决方案。文章以中海油服自研EMRT核磁共振测井仪首次在某大斜度井中使用钻杆传输方式成功应用为例,详细介绍了该类作业工程设计、参数优化、施工步骤、资料质控、操作要领、注意事项,基于该工程解决方案在现场实践中的优良表现、技术优势以及所解决的复杂地质问题,探索出了一套完整的钻杆传输核磁作业指导书,有效拓宽了核磁测井应用范围。该工程解决方案对后续作业具有一定指导意义。With the wide application of NMR logging technology in petroleum exploration,NMR logging has become common in vertical well and low inclination well,but it is rare to perform NMR logging in horizontal well and high deviation well.It is urgent to explore a complete set of engineering solutions.This paper takes the successful application of COSL self-developed EMRT NMR logging tool in a high deviation well for the first time as an example,and introduces in detail the engineering design,parameter optimization,construction procedure,data quality control,operation key points and cautions,based on the excellent performance,technical advantages and complex geological problems solved by this engineering solution in field practice.A complete set of PCL EMRT operating instructions has been explored,which effectively broadens the application range of nuclear magnetic logging.This engineering solution has certain guiding significance for the follow-up operation.
