简介Introduction

SusPENT悬浮剂用于“控滤失堵漏”，该技术是指当其配制的堵漏浆液进入漏失井段后，在钻井液液拄压力和地层压力所产生的压差的作用下，浆液从轴向流动转变为径向流动，在设置的时间内大量失水，浆液中的固相组份在重力作用下沉积变稠，形成滤饼，继而压实，填塞漏失通道，形成段塞，达到减缓漏失的效果；同时钻井液在所形成的塞面上形成光滑平整的泥饼，起到进一步严密封堵漏失通道的效果。

SusPENT suspending agent is utilized for "controlled filtration loss and leak sealing." This technology refers to the process where, after the leak-sealing slurry prepared with SusPENT enters the lost circulation zone in the well, under the pressure differential created by the drilling fluid column pressure and the formation pressure, the slurry transitions from axial flow to radial flow. Within a set time, a significant amount of water is lost from the slurry. The solid components in the slurry deposit and thicken under the influence of gravity, forming a filter cake. This filter cake is subsequently compacted, filling the lost circulation channels and creating a plug, thereby achieving the effect of reducing leakage. Meanwhile, the drilling fluid forms a smooth and even mud cake on the surface of the formed plug, further tightly sealing off the lost circulation channels.
