介绍了诱导作用的概念,首次提出了诱导作用存在的判断模式。W—1选择性堵水剂及FW-1高效调剖剂具有胶凝时间可调(3～40 h)、凝胶强度高(10×10~4～40×10~4mPa·s)等特点,在大庆油田使用后获得了极高的经济效益和社会效益。以诱导作用的判断模式为标准,对W-1选择性堵水剂及FW-1高效调剖剂延缓胶凝机理进行了分析,证实了诱导作用是该两种油田化学助剂延缓胶凝作用的关键。
Introduced the concept of induction, for the first time put forward the induction mode of existence. W-1 Selective Water Blocking Agent and FW-1 High Efficiency Profile Control Agent have the advantages of adjustable gelling time (3 ~ 40 h) and high gel strength (10 × 10 ~ 4 ~ 40 × 10 ~ 4mPa · s) , Obtained the extremely high economic efficiency and the social efficiency after using in Daqing oilfield. Based on the judgment model of induced effect, the mechanism of delaying gelation of W-1 selective water-blocking agent and FW-1 high-efficiency profile control agent was analyzed. It was confirmed that the induction effect was delayed gelation of the chemical additives of the two oilfields key.
