| 摘 要： | 充气钻井液是一种气，液，固三相物质均匀稳定分散的体系，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，文章例举了现场应用实例，通过渗漏试验，从泡沫群体的封堵作用，泡沫的疏水屏蔽作用，泡沫的流变特性以及其它方面探讨了充气钻井液防漏堵漏机理。

| Abstract: | Aerated mud is a kind of drilling fluid with gas,liquid and solid triphase matter distributed evenly and stably. 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.The leakproof and lost circulation mechanism of the aerated mud are discussed in the aspects of foam group's sealing action,foam's hydrophobic shielding action,foam's rheological behaviors etc.by practice example and leak test. |
