根据流体力学理论,研究了定向井注水泥的顶替机理,并提出了反映垂直井、水平井及定向井注水泥过程的数学模式。利用数值方法求解了垂直井、水平井的顶替模式,得出一些有用的结论。利用前人的实验数据,对本文的部分数学模式进行了验证,其吻合程度满足工程要求。

According to the theory of fluid mechanics,the cementing displacement mechanism in directional well has been researched and the mathematical model cementing process in vertical,horizontal and directional well have been developed.Some results have been gotten through solving the models of the vertical and horizontal well by use of numerical calculation.The partial mathematical models have been proven to meet the engineering requirements by use of the experiment data.
