稠油出砂冷系技术是20世纪80年代末、90年代初在加拿大发展起来的一项稠油开采新技术，它具有日产油量高、开采成本低的特点，是提高稠油资源利用率的一项十分重要的开采技术。河南油田从1996年起，开展了稠油出砂冷系技术攻关，从稠油出砂冷采机理、井筒降粘、混砂液处理以及 The heavy oil sand production cold technology is a new heavy oil recovery technology developed in Canada in the late 1980s and early 1990s. It has the characteristics of high daily oil production and low production cost, which is to improve the utilization of heavy oil resources A very important mining technology. Since 1996, Henan Oilfield has tackled the key technologies of sand production for heavy oil sands. From the cold sand mining mechanism of heavy oil, wellbore viscosity reduction, mixed sand treatment and
