Challenges and countermeasures of drilling fluid control on wellbore stability in extended reach Wells
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.
