辽河油田欢喜岭矿区高粘原油的储量较多,原油开采遇到的困难也较大.由于油品的粘度高,油流的阻力大,原油就很难沿井筒升举至地面.国外开采稠油的实践证明,往高粘重质油中加入低粘度的烃类稀释剂(如低粘原油、凝析油、柴油、煤油等),可明显地改善原油的流动特性.根据欢喜岭油田的条件——既有高粘原油,又有低粘原油,因此进行了往稠油中掺入稀油的降粘集输试验,并取得了明显的效果.
Huanxiling Mining Area, Liaohe Oilfield more high-viscosity crude oil reserves more difficulties encountered in the exploitation of crude oil due to the high viscosity of oil, oil flow resistance, crude oil will be difficult to lift along the shaft to the ground. The practice of oil proves that the addition of low viscosity hydrocarbon diluents (such as low viscosity crude oil, condensate oil, diesel oil, kerosene, etc.) to highly viscous heavy oil can obviously improve the flow characteristics of crude oil.According to Huanxiling Oilfield Conditions - Both high-viscosity crude oil, there are low-viscosity crude oil, so the viscosity of heavy oil into the viscosity of the collection and transmission test, and achieved significant results.
