| 摘 要： | 为了研究钻井、完井过程中钻井液、完井液渗入近井地层以及固体颗粒沉淀造成的地层损伤对油井产量的影响,考虑钻井液、完井液对石油的驱替,将其渗入地层视为动界面的渗流力学问题进行研究.得到了钻井液、完井液的锋面位置与时间的关系式、损伤与未损伤区石油的压力分布、损伤与未损伤情形下油井产量的表达式.该成果对石油、天然气、煤层气开采具有一定的参考价值和指导意义.

| Abstract: | Considering the effect of drilling liquid and well-finishing done liquid on oil driving,they are poured into the earth layer as dynamic surface seepage mechanics for researching the influence of oil well output produced by earth layer damage because of solid grain settling.The relation between the liquid frontal face location and time,the oil pressure distribution in damage and non-damage zone and the expression of oil well output in the two situations are obtained.The results have some referent value and g... |
