摘　　要：介绍了地层评价随钻测井系统的仪器结构、工作原理。阐述了基于前导模拟技术的随钻地质导向方法;综合运用随钻测井、电缆测井、气测和录井资料等信息,建立了时间推移测井识别油气层的方法。通过对长庆油田28口井的应用效果分析,地层评价随钻测井缩短了钻井周期,解决了水平井精确入窗、控制井眼轨迹在油气层中穿行及常规电缆测井系列油气识别难的问题,取得了良好的地质效果,具有广阔应用前景。Introduced is the structure, operational principle, performance of the Formation Evaluation Logging While Drilling system. By elaborating the forward modeling based on Resistance-Gamma model and the meticulous formation evaluation process, we establish time- lapse logging technology combining with LWD, cable logging, gas logging and so on. By analyzing the log applications of 28 wells in Changqing oilfield, LWD shortened the drilling period, solved the problems of accurate hitting the target, controlling the trajectory of the well and oil-gas identification in conventional cable logging. Practical applications show that the LWD technologies have acquired favorable result and have great application prospect.
