摘　　要：对大位移井钻井液在井壁稳定性控制中的挑战进行了系统研究。通过分析井斜变化、长水平段及高温高压条件下钻井液性能的衰减问题,提出了优化流变参数、提高封堵能力和优化抗高温高压钻井液体系等对策。研究结果表明,这些优化措施有望改善钻井液的防塌性能和泥饼质量,有效提升井壁稳定性。The challenge of drilling fluid in wellbore stability control of extended reach Wells is systematically studied.Based on the analysis of the variation of well inclination,long Horizontal section and the attenuation of drilling fluid properties under High temperature and pressure conditions,some countermeasures such as optimization of rheological parameters,improvement of plugging capacity and optimization of drilling fluid system resistant to High temperature and pressure are put forward.The results show that these optimization measures are expected to improve the anti-collapsing performance and mud cake quality of drilling fluids,and effectively enhance the stability of borehole walls.
