稠油降粘方法研究现状

Heavy Oil Viscosity Methods

稠油具有密度大、粘度高、轻油含量少的特点,使得开采和输送稠油的工艺难度大,增加了开采和输送的成本,为了能够合理、经济地开采和输送稠油,必须对其进行降粘。对目前稠油开采和输送中的降粘方法及应用概况进行了研究,包括开采中所应用的蒸汽吞吐、蒸汽驱、火驱法和输送中所应用的乳化降粘法、稀释法、低粘液环输送法、添加油溶性降粘剂法。

Overview of the heavy oil exploitation and transportation in the current commonly used method of viscosity reduction and application. Including mining in the application of steam stimulation, steam flooding, fire-drive, law and in the delivery of application emulsion viscosity reduction method, dilution, central low mucus transport law, add oil-soluble viscosity reducer law.
