| 摘 要： | 井漏严重影响钻井安全，漏层参数的量化对于成功堵漏至关重要。文中试将油田开发阶段的试井理论拓展应用于钻井过程，根据试井解释原理，绘制了无因次压力和无因次压力导数与无因次时间关系的标准拟合图版；利用钻井过程中压力落差测试资料与标准图版拟合，对均质孔隙介质地层和天然微裂缝地层的漏层渗透率、孔隙半径、裂缝宽度等参数进行了定量计算。根据计算结果可以选择合适的堵荆种类。现场施工表明，该方法的解释结果对堵漏施工作业有很好的指导作用。 |

| Abstract: | Circulation loss severely impact the drilling safety. It is very important that some parameter about leak layers can be quantitatively calculated. The theory of well testing is applied to the process of drilling. Based on the principle of well test interpretation, the normal fitting plate of dimensionless pressure and relation of dimensionless pressure derivative and time are drawn. The permeability, pore radius and fracture width are calculated by using differential pressure testing data and normal chart. On the basis of calculation result, the proper lost circulation materials are selected. It has been validated that the interpretation result is very useful to drilling. |
| Keywords: | drilling circulation loss well testing interpretation differential pressure |
