| 摘 要： | 介绍了一种适用于高矿化度条件下的新型水溶性降粘剂,主要针对新疆某油田水资源缺乏、油品为特超稠油的井筒降粘问题,其配方为0.05%HSF 0.05%XY-1 0.05%W.这种降粘剂具有显著的抗盐性能,实验中用进行简单水处理后的地层采出水配制该降粘剂,对于超、特稠油能起到显著的降粘效果.并探讨了一种油溶性降粘剂,对高含沥青质胶质稠油的降粘研究做出了有益的尝试.

| Abstract: | In this paper a new type of water-soluble viscosity reducer in high salinity water, which can be used in super-extra viscous crude oil production in wellbore, has been demonstrated in the lab. For the lack of clean water in an oil field in Xinjiang, the technology makes it possible to make use of formation water after a simple treatment. The formulation is 0.05%HSF (0.05)%XY-1 0.05%W. The viscosity reducer has a strong salt resistance. In the experiment, if the viscosity reducer is formulated by the formation water after the simple treatment, it also can obviously reduce the viscosity of the super-extra viscous crude oils. This paper also demonstrates that an oil-soluble viscosity reducer can be used to reduce the viscosity of crude oil containing high asphalt and gum. |
