摘　　要：有机垢是引起稠油油藏储集层损害的主要原因之一。结合临盘油田盘河区块稠油油藏的实际情况,进行了温度、原油成分及注入速度对有机垢形成的影响的实验研究。实验结果表明,温度下降、原油组分改变、流速变化均能促进有机垢的形成,导致油层渗透率显著下降。给出了控制有机垢形成的相关技术措施。The organic scale is one of the main reasons that damage the heavy oil sandstone reservoirs. The purpose of experiment is to observe the change of the core's permeability caused by the organic scale through changing some lab parameters such as temperature, oil component and velocity. The result shows that these parameters' changes are the main factors that cause the reservoir permeability to drop obviously. The technique and measures used to stop organic scale formation is put forward in the article.
