摘要
LDLT5450岩性密度测井仪是一种双源距、双能谱,利用光电效应和康普顿效应区分地层岩性和测量地层密度的测井仪。由于测井环境比较恶劣以及仪器测量原理的限制,造成测井曲线异常是多方面的。本文就电子线路与探头连线的绝缘、仪器的刻度、测井环境等方面造成的测井异常进行分析,以及怎样克服这些问题提出建议,以期对仪器正确使用提供帮助。
LDLT 5450 litho-density logging tool is a double source distance and dual energy spectrum tool wihich distinguishes formation lithology and density with photoelectric effect and Compton effect.Log abnormity is various because of harsh logging circumstances and restriction of measuring principle.In this paper,according to the electronic circuit and probe connection insulation,instrument calibration,well logging abnormity analysis caused by the environment and how to overcome these problems,suggestions are made to help use the tool correctly.
