摘　　要：硼中子寿命测井与放射性同位素示踪测井相比,具有测井方法灵活、测井适应性强、不产生放射性污染、测井施工后不影响作业施工时效的优点,在采油井还可兼具监测剩余油。硼中子寿命测井成本高、施工工艺较为复杂,测井效果在很大程度上取决于现场施工工艺控制。在现场施工中,要根据井况分别采用"测-注-测"和"测-注-渗-测"两种施工工艺进行测井。其在套管井找窜和在水平井找窜中的应用,都有效避免了放射性同位素示踪测井引起的沾污及污染问题。Compared with radioisotope tracer logging, boron neutron li{etime logging is more flexible, better--adapted, of no radioactive contamination and reliable for guaranteeing operation aging. And at the same time, it is also used to monitor remaining oil in producing wells. However, it costs much and has more complicated operation technology so that logging result depends largely on site control over the technology. Two logging technologies----log- ging- injection-- logging and logging-- injection-- seepage-- logging-- -- are respectively used in site operation accord- ing to well conditions. Their application in discovering channeling in cased wells and horizontal wells contributes to effectively avoiding contamination caused by radioisotope tracer logging.
