摘　　要：以稠油开发为主的曙光油田进入中后期开采阶段后,随着含水率升高,集输和水处理系统中含油污泥产出量增大,稠油含油污泥处理困难、成本高。针对该问题,结合稠油蒸汽吞吐中动用不均、汽窜等开发矛盾,在含油污泥组分分析的基础上,深入封堵机理研究,以含油污泥为主要原料研制含油污泥调剖系列堵剂,配套设计段塞组合、施工工艺、地面流程及专用设备,用于稠油热采井的调剖封窜。实际应用表明,该技术可有效动用中低渗透层、缓解汽窜,在改善开发效果的同时实现含油污泥的绿色资源化利用,节约含油污泥处理成本,具有广阔的应用前景。The increased amount of oil sludge from heavy oil thermal recovery when Shuguang oilfield enters the middle and late stage of exploitation had pose pressure on the treatment of the sludge,and increasing the cost of such treatment.Based on the analysis of the composition of oil sludge,combined with the uneven usage of heavy oil steam stimulation,the sludge based product series for plugging were gradually developed.The supporting slug combination,surface engineering process and equipment were also developed to seal channeling in heavy oil wells.According to the past practical application,this technology could effectively utilize the middle and low permeable layer,alleviate the steam flow,improve the development effect,realize the green resource utilization of oil sludge,and save treatment cost.Therefore,this type of technology has showed a promising prospect for a broad application.
