- The model can be used to determine formation pore pressure and the optimum drilling fluid density to stabilize borehole. 利用该模型可确定地层孔隙压力和保持井眼稳定的最优钻井液密度等参数。
- Formation drillability is related to formation compact degree and pore fracture degree,so NDR can reflect formation pore pressure state. 地层可钻性与地层的压实程度和孔隙破裂程度有关,因此NDR可以反映地层孔隙压力的情况。

- The rock drillability has close connection with sonic interval travel time and formation pore pressure can be reflected by it in some degree. 地层孔隙压力在一定程度上可由测井声波时差来反映。
- By maintaining drilling fluid pressure above rock formation pore fluid pressure, there is a natural tendency for the drilling fluid to enter permeable rock in the formation. 而如果保持钻井液压力高于岩层孔隙流体压力,钻井液就会出现向岩层的透水岩石中渗入的自然趋势。
