| Abstract: | Combination of flexible deviation correction and prevention drilling tools can control the increase of deviation of the drilling well effectively while the rate of penetration(ROP) is increased,and can decrease the deviation also.It provides us a new type of the combination of drilling tools for the big inclination angle and hard stratum area,in which deviation is very easy to be encountered during drilling.In this paper,we introduce the mechanism of deviation correction and prevention of the combination of these flexible drilling tools;meanwhile,analyze the mechanical model of this type of drilling tools,then put forward the deviation correction and prevention drilling technical measure. |

| Keywords: | flexible joint deviation correction and prevention combination of drilling tools working mechanism me- chanical model |
