由于含有大量高切力、高结构粘度的泡沫，在低压渗漏地层有显著的防漏堵漏作用。
It has obvious actions of leakproof and lost circulation in low pressure absorbent formation because of containing a lot of foam with high shear force and high structural viscosity.
侧向水力工具在现场的应用情况表明：（1 ）利用侧向水力工具形成“人造井壁”屏蔽环的方法，在渗漏地层能起到较好的防漏作用；
Its application shows that:(1)a"mall-made borehole wall"produced by the side hydraulic tool plays a role of leak protection in the absorbent formation;
