中原油田钻调整井时常发生恶性漏失，特点是漏失层位多，漏层微裂缝尺寸随压力波动而变化。选用QPL－Y高强度井壁封固剂配成随钻防漏堵漏钻井液后，不同粒径的微细活化颗粒随钻井液进入漏层，形成水化铝酸钙、水化硫铝酸钙等水化产物，与微细活性纤维、膨润土颗粒、沥青颗粒和高聚物分子等形成网架结构，在高温高压下凝结固化，将破碎性裂缝漏层牢固地粘结封固起来，提高漏层的承压能力。经文51—191等6口井试验，成功率为100％。
In the Zhongyuan oilfield, the well drilled often has a vicious loss of leakage, which is characterized by a large number of lost layers and the size of the microfractured layer varies with pressure fluctuations. Use QPL-Y high-strength wall sealant dubbed drilling leak-proof plugging drilling fluid, the different sizes of fine activated particles with the drilling fluid into the drain layer, the formation of hydrated calcium aluminate, hydrated calcium sulfoaluminate And other hydration products, and fine active fibers, bentonite particles, asphalt particles and polymer molecules form a network structure, solidified under high temperature and pressure curing, the fracture of the leakage layer firmly bonded solid sealing leak to improve the drain layer The pressure capacity. Verses 51-191 and other 6 wells test, the success rate was 100%.
