采用物理模拟和化学模拟方法研究了油田堵剂的智能作用。结果表明,油田堵剂能感知地层渗透率及厚度的大小,优先进入高渗透层,进入地层的量与地层厚度成正比。同时,油田堵剂还能感知地层水矿化度及流动介质(如油、水等)的变化,其体积及封堵性能随之发生相应的变化,由此可见,油田堵剂都是具有选择性的智能型堵剂。在一定条件下,堵剂的堵水能力高于其堵油能力。
The intelligent effect of plugging agent in oilfields is studied by physical simulation and chemical simulation. The results show that the blocking agent in the oilfield can perceive the formation permeability and the thickness, and preferentially enter the high permeability layer. The amount entering the formation is proportional to the thickness of the formation. At the same time, the oilfield plugging agent can also perceive the formation water salinity and the flow medium (such as oil, water, etc.) changes in the volume and sealing performance corresponding changes occur, we can see that the oil field plugging agent is a choice Sexual intelligent blocking agent. Under certain conditions, plugging water blocking capacity is higher than its capacity to block oil.
