摘　　要：随钻测井相对于电缆测井更有优势,它可以消除井眼环境和泥浆滤液的侵入的影响,更真实地反映原状地层的地质特征。自主研发的成套随钻测井仪已经开始投入使用,现在比较常用的是用MWD与GIR随钻组合仪进行测井,它能够快速直接识别地层,从而准确指导钻井的方向,提高钻井效率,比单独的MWD测量更为准确。随着随钻测井在国内的逐步发展和应用,其优势也越来越明显。LWD relative cable logging has more advantages.it can eliminate the borehole environment and the influence of mud filtrate invasion and more realistically reflect the original formation of geological features. The LWD instrument sets which independent research and development by CNPC logging company has already begun to put into use. Now more commonly used with MWD and GIR LWD combined instrument in logging, it can quickly identify the lithology of the formation and to accurately guide the direction of drilling, therefore drilling be more efficiency, it is more accurate than only use MWD measurement. With the LWD in the progressive development and application of the domestic, the advantage has become increasingly evident.
