中文摘要：
针对XS-001H气体钻井水平井段的井眼轨迹控制问题,建立了全井段水平井井斜控制的有限元模型,该有限元模型可以任意调整水平段钻具组合参数和稳定器的安放位置来进行井斜控制的力学机理研究。重点研究了钻铤钻具组合、无磁抗压缩钻杆钻具组合、稳定器不同安放位置与井斜控制的力学机理和关系,并得到了相应钻具组合下,钻头侧向力与稳定器间距的定量关系曲线,不同钻具组合在水平段的最大挠度与稳定器的变化关系曲线,这些结果为气体钻水平井段的井斜控制提供了定量的理论数据,并得到了现场应用。
英文摘要：
Aimed at the problems of the well track control on the horizontal hole section of the XS-001H well, the finite element model of the well deviation control on the horizontal hole section is established. The parameters of the horizontal hole section BHA and the locations of the stabilizers can be arbitrarily changed to study the mechanism of the well deviation controls in the FEM model. The relationships of the drill collar BHA, the non-magnetic resistance compress drill pipe BHA, and the stabilizer locations and the mechanism of the well deviation controls are studied in this paper. The quantitative relation curves between the lateral force of the three-cone bit and the stabilizer interspacing are obtained under the relevant BHA, and the curves of the maximum bending deflection of the different BHA on the horizontal hole section and the stabilizer interspacing are also obtained. The results provide the quantitative theoretical data for the well deviation controls of the gas drill horizontal hole section.
