摘　　要：辽河油田已进入中后期开采阶段,随着含水率升高,集输系统中污油泥大量囤积。针对该问题,在分析污油泥组分和粒径的基础上,以不同种类污油泥做为调剖剂的主要原料,添加适当的化学药剂和固相颗粒等添加剂,研制出污油泥超细颗粒调剖剂、污油泥高分子聚合物调剖剂和污油泥高温改性封口剂3种污油泥调剖剂,通过段塞组合,用于稠油蒸汽吞吐井的调剖封堵。实际应用表明,该技术可有效动用中、低渗透层,节约调剖成本,并解决了污油泥处理难题,值得大力推广应用。Liaohe Oilfield has stepped into middle-late development stage and a large number of heavy-oil sludge accumulates in gathering system with the increase of water-cut. Based on the analysis of heavy-oil sludge composition and grading,different heavy-oil sludge types are taken as main raw materials to develop 3 sludge profile-control agents by adding appropriate chemicals,solid particles and other additives. The 3 profile-control agents include heavy-oil ultrafine particle sludge profile-control agent,polymer sludge profile-control agent and high-temperature modified sludge sealing agent. The sludge profile-control agents can be applied for profile-control and plugging in heavy-oil steam huff-puff well by slug combination. Field application shows that the sludge profile-control agents can effectively improve the development performance of middle-low permeability reservoirs,save profile-control cost and make full utilization of heavy-oil sludge,which is worth spreading andapplication.
