钻井液在钻井过程中发挥调解油层与外界压力、外界与泥浆的压力,而一旦钻井液在钻井过程中大量流入油层,就会带给油层巨大的破坏,不利于原油的开采。本文基于生产经验,探索改进了一种高性能疏水暂堵剂,研究了其制备过程及物性,以期应用于生产,提高工作效率。 Drilling fluid plays a role of regulating the pressure of reservoir and external pressure, the pressure of outside world and mud during the drilling process. Once the drilling fluid flows into the reservoir in a large amount during drilling, it will bring huge damage to the reservoir and is not conducive to the exploitation of crude oil. Based on production experience, this paper explores and improves a high-performance hydrophobic temporary plugging agent, and studies its preparation process and physical properties so as to be applied to production and improve work efficiency.
