粘结－滑动、钻头跳钻及井下总成的回转等现象，在钻井作业中对井下设备都是有害的。这就是为什么Ｇｔｏｓｅｒｖｉｃｅｓ公司与法国石油研究院要开发ＡＬＳＥＶＥ软件的原因。他们的一个简单目的就是，尽早地发现损伤钻柱的潜在振动。软件系统可以评价井下转速及钻头的垂直
Bonding - sliding, drill bit drilling and downhole assembly and other phenomena of rotation, downhole equipment in drilling operations are harmful. This is why Gtoservices and the French Petroleum Institute are developing ALS-EVE software. One of their simple goals is to find the potential for damaging the drill string as soon as possible. Software system can evaluate downhole speed and drill vertical
