摘要
为避免在井下没有搅拌装置的条件下,水溶性催化剂在水热裂解反应中难以与稠油充分接触,制备油溶性的油酸镍作为水热裂解反应的催化剂.结果表明:油溶性催化剂优于水溶性催化剂;辽河稠油、30%(质量分数)地层水和0.4%(质量分数)油酸镍在200℃反应24 h后稠油降黏率可达63.1%;0.1%(质量分数)甲苯与催化剂协同进行水热裂解反应,稠油降黏率可达81.3%;稠油组成发生重组分减少,轻组分增加变化.
The heavy oil and the catalyst cannot be fully contacted without stirring in down-hole.The oil-soluble catalyst is prepared in order to resolve the surface problem.The oil-soluble catalyst is better than water-soluble catalyst without stirring.The results show that the viscosity reduction rate can reach 63.1% after the quathermolysis reaction using heavy oil 30% water and 0.4% oil-soluble nickel oleate as catalyst at 200 ℃,24 hr and the viscosity reduction rate can reach 81.3% with the synergistic effect between the catalyst and 0.1 toluene.The components of heavy oil are changed in which the light components increased and heavy components decreased.
