摘要
为了实现石油测井中井眼轨迹测量,提出了一种基于光纤陀螺油井测斜系统的设计和实现方法,将捷联惯性导航技术应用到油田测井领域。整个系统是以高速数字信号处理器TMS320VC33为核心实现数字滤波和导航解算,以FPGA设计为辅完成DSP外围接口功能,实现对水平井的井斜角、方位角和工具面角的测量。该文重点介绍了惯性测量单元、数据采集与接口电路、通讯电路和导航计算机等方面进行硬件和软件设计,并对已完成的试验样机进行全面测试,达到预期的基本要求。
A new inclinometer logging technology was presented to realize eyes orbit measurement in petroleum drilling. The strapdown inertial navigation technology was briefly introduced, and the structure design of FOG utilized in Measurement-While-Drilling surveying system was studied. High speed digital signal processor TMS320VC33 was core in the whole system to accomplish digital filter and calculation, and field programmable gate array （FPGA） was assistant to accomplish function of interface circuit. System hardware and software of FOG utilized in Measurement-While-Drilling surveying technique was designed from inertial measurement unit, data sampling, interface circuit to navigation computer etc, the inclination, the azimuth and the tool face angles of horizontal drilling wall was determined. The experimental system was achieved, and the system static work has reached the anticipated designing requirement under the normal temperature, at present.
