常规调剖剂作用时间短,当进入地层后,在井筒附近就产生了堵塞,改善井筒附近的产层结构,后续注入水只能进入次大孔道,主要提高了次大孔道的波及系数。对于层间窜流严重的油层,后续注入水很快绕过堵塞区,重新回到高渗透条带。本文主要探讨含油污泥深度调剖技术在油田生产过程中的应用。 Conventional profile control agents have short acting time. After entering the formation, clogging occurs near the wellbore to improve the structure of the pay zone near the wellbore. Subsequent injection of water can only enter the sub-large channels, mainly increasing the sweep coefficient of the second large channels. For reservoirs with severe channeling, the subsequent injection of water quickly bypassed the blockage zone and returned to the high permeability zone. This paper mainly discusses the application of oil-bearing depth profile control technology in oilfield production process.
