摘　　要：桑塔木油田已处于开发高含水阶段,原油油品胶质、沥青质含量高,容易发生沥青析出沉积,给开发带来了巨大困难。介绍了桑塔木油田原油中沥青存在的状态、沥青含量对沥青析出的影响,通过室内实验描述了沥青析出的机理,结合现场总结了沥青析出的影响因素,提出了防止沥青析出的方法,通过实际生产在桑塔木油田取得了较好的效果,为类似油田开发提供参考依据。Sangtamu oilfield is in high water cut stage, with crude oil properties, prone to asphalt precipitation, bringing great difficulties to oil production. This paper introduces the influence of state and asphalt content of asphalt in the crude oil in Sangtamu oilfield. The mechanism of asphalt precipitation was described by laboratory experiments. The paper summarized the influencing factors of asphalt precipitatio, proposed methods for preventing the precipitation of asphalt. So the actual production has achieved good effect in Sangtamu oilfield, providing reference for similar oilfield development.
