| 摘 要： | BN—3井测井过程中因意外事故造成带有放射性源的测井仪器掉入井中，而常规打捞技术已不能满足复杂井眼中的放射性测井仪器的打捞要求，为此，采用磁定位仪在钻具水眼中测仪器落鱼鱼顶，并利用弯接头配合打捞筒进行测井仪器打捞，顺利地将落井器及电缆全部捞出，且测井仪器完好无损。详细分析了该井事故处理难点，并给出了相应的事故处理方法。

| Abstract: | Logging instrument with radiation source dropped accidentally in the well bore during logging operation. Conventional fishing methods can't fish logging instrument's in the complex borehole. This paper presents the analysis of the fishing difficulties and corresponding measures. Magnetic locating instrument was settled down the inside of the drill pipe to detect the fishing top, and overshot accompanied with bent sub was used to fish the instrument. |
