摘　　要：固井工程是一项应用工程,是建井过程中的重要环节,它直接影响钻井周期和建井成本,以及油田开发方案的实施。深井、超深井的井下地质条件非常复杂,对固井质量有许多不利的因素,在井下条件确定的情况下,决定性的因素是环空流动的壁面剪应力,它是影响顶替效率的主要因素。Cementing is an application engineering project, is an important part of well building process, it directly affects the cost of drilling cycle and building cost and oil field development program implementation. Deep well and ultra deep well are complicated in the underground geological conditions, which give many adverse factors. When underground conditions are confirmed, the determining factor is air flow in the wall shear stress; it is the main factor influencing the displacement efficiency.

关 键 词：壁面剪应力 固井质量 顶替效率 偏心环空
