摘要
Abstract
The sealing characteristics is an important evaluation index of oil-based drilling fluids. Improving the plugging ability of oil based drilling fluids favors hole stability and fast drilling safety. A new method has been established to evaluate the sealing characteristics by using sand core funnel simulating micro-fracture. Experiment results have shown that the addition of nano materials CQ-NZC can make permeability lower and have good performance on plugging. The micro morphology analysis has been used to study the mechanism. The experiment results indicated that CQ-NZC and asphalt plugging agent agglomerated together partly to form hole plugging particles which contributed to the improvement of plugging ability.关键词
