查询词典 drill

The inclined capacity of BHA is analyzed, which is affected by various parameters. It is shown that the lateral force of drill bit and inclined capacity of BHA have something to do with the parameters(the distance between drill bit and the first stabilizer, outside diameter of the first stabilizer, WOB etc).

分析影响常用钻具井斜性能的因素，得到了近钻头稳定器与钻头间距变化、稳定器工作外径变化、钻压变化等能够改变钻具井斜性能；同时以一组双稳定器钻具组合为例，分析钻具节点的位移变化图、弯矩图和应力分布图可得出钻具上的受力变形情况。

In the depth scope ranging from 1100 meters to 3500 meters, the direction of the middle principal stress becomes vertical.The simulation result, from the modelling of the Kun 2# drill and its vicinities, suggests that the vertical stress variation is relatively small in the place 3 to 7 times of the drill diameter from the well wall, but the horizontal stress varies in some trend. Moreover, the direction of the minimal stress component and the remote loading pressure take place large deviation in southeast direction.
