摘 要:
通过对导向钻具复合钻进的力学特征及影响底部钻具组合的设计因素分析,指出导向钻具组合利用弯螺杆的力学特性可以一趟钻实现增降稳等多种功能,有助于提高钻井效率;由于螺杆弯角对钻头侧向力影响较大,需合理使用;在倾角较大区块应综合考虑钻柱自身及地层特性的影响,同时可利用导向钻具复合钻进特点设计井眼轨迹。[著者文摘]

Abstract:
Through the analysis to the mechanical behavior of guiding drilling tool multiple drilling and the design factors of affecting bottom drilling tool combination, this paper pointed out that it is helpful to improve the drilling efficiency to use the mechanical features of the bend bolt bar to do one tripping drilling, it is necessary to use it reasonably because there is a serials affection to the drill bit site force by the bend angle of bolt bar,and it should be considered synthetically in the block with bigger slope angle to the affection caused by the drill post itself and the earth layer behavior and the well track can be designed at same time by using the combined drilling features of guiding drilling tool.[著者文摘]
Key words:
guiding well drilling; stabilizer; slope making; mechanical behavior
