摘要
针对在套管井等无磁环境中磁通门无法获取有效的运动轨迹参数等问题,提出了光纤陀螺井斜方位测井仪的研制。仪器采用了新型的小直径精密三轴一体化光纤陀螺和三个石英加速度计作为核心传感器。文章从仪器的实现方案、测量原理、构成等方面作了阐述,针对影响光纤陀螺的主要因素温度及漂移补偿等关键技术,给出了重点研究,并通过大量试验进行验证与改进。
To solve the problem that the instruments can not obtain effective trajectory parameters without magnetic fields interference in tube wells,the article introduces a new logging tool,the optical fiber well logging tool,hangering the system of ECLIPS5700.A new critical little diameter optical fiber gyrometer and three quartz accelerometers are used as core sensor.The system's project,composition,measuring principle are proposed.This article focuses on compensation for temperature drift and other critical technologies.The new instrument is verified and improved by many tests.
