摘    要: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。

关 键 词:堵水剂  剖面调整  智能材料  地层  渗透率  模拟试验

Abstract:Physical and chemical simulation methods were used to investigate the intelligent characteristics of water shutoff agents. It is proved experimentally that the water shutoff agents are the selective and intelligent materials. The quantity of water shutoff agents flowing into the formation is changing with the permeability and thickness of the stratum. The variation of salinity and flowing medium may lead to a corresponding change of their volume and plugging properties. That is, the water shutoff agents can be sensitive to permeability and thickness of the stratum as well as the variation of salinity and flowing medium.
Keywords:water shutoff agent  profile control  intelligent materials  formation  permeability  simulation test
