摘要
旋转磁场测距系统是保障连通井和成对水平井等特殊工艺井顺利实施的重要随钻测量系统。该系统通过测量磁短节旋转产生的低频交变磁场,实现磁短节与测量探管之间的空间定位,然后通过井下动力钻具控制两井的井眼轨迹连通或平行。现场试验初步验证了该系统的可行性、稳定性和可靠性,为系统进一步改进提供了技术支撑。
Rotating Magnetic Ranging Service is an important measure while drilling, which can be used in connected wells and parallel wells. It can measure the relative space position between magnetic sub and probe by alternating magnetic field, then control well tracks connection or parallel by drill motor. Feasibility,Stability and Reliability of this system were verified by field test. It can provide support for improve the system performance.
