| 摘 要： | 通过试验得到泵功率、围压和喷距等参数对钻速的影响,应用数学分析方法建立水力喷射侧钻径向水平井钻速方程,将试验和理论推导相结合给出钻速方程的求解方法。结果表明:钻速随着泵功率的增加以指数关系变化,指数一般小于1,钻井液黏度越大指数越小;钻速随着围压的增大而逐渐减小;钻速随着喷距的增大先增大后减小。

| Abstract: | The influence of pump power, ambient pressure and standoff distance on drilling rate was researched by an experiment. Drilling rate equations of hydraulic jetting lateral drilling radial horizontal well were established by mathematic analytical method. And the solution method of the drilling rate equations was provided on the basis of theoretic analysis and experiment. The results show that the drilling rate increases exponentially with the increase of pump power, and the index is usually less than 1.0 and decreases with the drilling fluid viscosity increasing. The drilling rate decreases with the increase of ambient pressures and increases firstly and then decreases with the increase of standoff distance. |
