摘要:: 凝析气藏采用加入水合物抑制剂的方法预防输送过程中水合物的生成,为了研究不同类型抑制剂的协同作用效果,基于对水合物热力学抑制剂与动力学抑制剂作用原理的分析,通过实验对动力学抑制剂(聚N-乙烯基吡咯烷酮)与热力学抑制剂(甲醇、乙二醇)的复合效果进行研究,重点研究了动力学抑制剂含量对醇体系抑制效果、不同醇含量体系对动力学抑制剂抑制效果的影响,选择性地实验了一定矿化度水对抑制效果的影响。结果表明:聚N-乙烯基吡咯烷酮与醇体系具有很好的配伍性,相互之间具有促进作用,二者复配可以有效提高抑制效果。

Abstract:: For a gas condensate reservoir, hydrate inhibitor is added to prevent the generation of hydrate in transportation. In order to study the synergistic effect of different inhibitors, the actions of thermodynamic and kinetic inhibitors are analyzed, and the composite effects of kinetic inhibitors (poly N-vinyl pyrrolidone) and thermodynamic inhibitors (methanol, ethylene glycol) are studied through experiments. Particularly, the effect of kinetic inhibitors on alcohol system and the impact of systems with different alcohol contents on the inhibitory effect are studied emphatically. The impact of certain salinity water on inhibitory effect is selectively tested. The results show that poly N-vinyl pyrrolidone is compatible with alcohol system, and they interact with each other and can be compounded to effectively improve the inhibitory effect.
