摘　　要：常规稳定器和钻铤构成的底部钻具组合(BHA)其力学特性不能改变,若与实际要求不相符合时,必须起下钻更换。常规稳定器在缩径地层起下钻易阻卡,钻进时,泥浆循环阻力大,不利于携岩。研制的钻井遥控变径稳定器(RCDS)在现场应用表明,能克服常规稳定器的不足,提高井身质量,是值得推广的井眼轨迹控制工具。When the mechanics performance of BHA （Bottom Drilling Assembly）, that consists of conventional stabilizer and drilling collar, can not meet actual operation, it has to be changed. Conventional stabilizer will get stuck when it moves down into reduced borehole. When drilling, it gives big resistance to mud circulation, which is not beneficial to bring up cutting. Its practical use in oilfield shows that remote control diameter-changeable stabilizer （RCDS） can get over short comings of conventional stabilizer, thus well quality is improved. It is worth while to be used as a tool in borehole con,rolled-track.
