随着油气勘探开发的深入,钻探的高温高压和复杂地层井越来越多,井壁不稳定、井漏和井塌等问题时有发生,给钻井施工带来了一定的安全隐患.钻井液中的微纳米封堵剂通过有效封堵地层裂缝和孔隙,能够提高井壁稳定性,减少井漏发生的风险.对钻井液微纳米封堵性能评价方法进行研究,为对钻井液进行合理的评价奠定基础.
Research progress on evaluation methods for micro nano plugging performance of drilling fluids
With the deepening of oil and gas exploration and development,there are more and more high-temperature,high-pressure,and complex formation wells being drilled.Problems such as unstable wellbore,well leakage,and well collapse often occur,which bring certain safety hazards to drilling construction.Micro nano plugging agents in drilling fluids can effectively block formation fractures and pores,improve wellbore stability,and reduce the risk of wellbore leakage.The main purpose of this study is to investigate the evaluation method of micro nano plugging performance of drilling fluids,laying the foundation for a reasonable evaluation of drilling fluids.
