| Abstract: | present and in the future, the drilling mission will concentrate on deep drilling, ultradeepdrilling, sidetrack drilling and slimhole drilling. The side cutting character of mono-cone bits, the interact betweenthe bit and rock and it's thermal stress distribution are studied in this paper. At the sarne time, this paper alsoanalyzes some factors that influence mono-cone bit pefformance such as bit structure, stratigraphic property anddrilling operation paramters. From the reseaxch result, it is reached that mono-cone bit has more poWerful side-track cutting capacity and longer interact time between the bit and the rock. The mono-cone bit must have awidely prospect in the future because it can be used under low rot8Lry rate and high weight on bit. |
