连续油井测斜系统仿真轨迹数据生成技术

针对快速准确的油井轨迹测量要求,一种基于动力调谐陀螺的连续测斜方法被提出。为了对连续测斜算法的可行性进行仿真,需要井眼轨迹数据和惯性器件输出参数。根据惯性导航原理,将飞行轨迹生成思想扩展到油井测斜领域。应用数学方法设计了一种仿真用井眼轨迹数据生成器,搭建了惯性器件模型,生成了模拟的惯性器件输出。通过指北方位捷联惯导姿态算法仿真,验证了该轨迹数据生成器能够满足连续测斜算法的仿真需求。

Track Data Creation for Continuous Wellbore Survey Algorithm Simulation

To achieve the fast and precise survey goal, a dynamically tuned-gyro based continuous survey system was suggested. Wellbore track data and inertial components outputs are needed when continuous wellbore survey algorithms are simulated. Flight track data creation method was extended to the wellbore survey field, a track data generator was designed and the inertial component models were built, so simulation inputs were provided. The track data generator bases on inertial navigation principles, and creates inertial components outputs by mathematic method. The strapdown inertial attitude algorithm simulation results verify its effectiveness.
