摘要
本文提出了斜直井内多扶正器钴柱空间弯曲变形的计算模型。通过Laplace变换,获得该问题的解答。利用本文提出的计算方法,对于确定的井身设计,根据相应的地层情况,在满足文中所叙述的条件下,可得到钻具组合以及钴井参数的选择原则。
In this paper, we present the calculating model of three-dimentional buckling of lower drill string with multi-stabilizers in beviated-straight borehole. By Laplace transformation,we obtain the solution to the problem. Meanwhile, for the definite design the rules of selecting the string combination and the drilling parameters can be determined according to the condition of drilling straight hole and of corresponding formations by the calculating method in this paper.
