摘　　要：利用微量量热法测定了一种水溶性高分子NCP与表面活性剂SDS(十二烷基硫酸钠)、原油、油砂的热效应,实验结果表明NCP与SDS、原油、油砂存在明显的热效应,说明它们间存在以静电力为主的超分子化学作用,并通过实验测定了在驱油过程中应该控制的浓度范围,为实际驱油提供了一定参考。NCP is a new kind of water- soluble cationic polymer. It has much special performance that has not been investigated in details. It has good affection used as oil displacement agent, which has been testified through edge- water encroachment experiment, and the oil - displacement mechanism is different from surfactant and HPAM. Considering of the special structure and the electropositive of NCP, it can be predicted that NCP with surfactant, petroleum and oil sand has strong interaction. The microcalorimetry experiment was carried out to testimony the degree of these interactions. The interaction is a kind of supermolecular interaction, and electrostatic force, van der waals force, hydrogen bond and hydrophobic bond were included.
