摘　　要：综述了目前油田常用的15类药剂,主要包括预交联凝胶颗粒、聚合物凝胶、体膨颗粒、泡沫、改性材料等,其中聚合物凝胶仍是目前油田应用最广的堵剂。在此基础上,也发展出复合调驱、压裂+堵水、堵调+深部调驱等工艺,后期通过对湿相改性可膨胀石墨、新型稀释无机沉淀剂、活性老化堵油剂、高强度堵漏复合材料进行论证,结合发展的新工艺,能够进一步提高油藏的采收率。Fifteen kinds of agents commonly used in oilfield were reviewed,including pre-crosslinked gel particles,polymer gel,bulk expansion particles,foam and modified materials,among which polymer gel is still the most widely used plugging agent in oilfield.Based on this,composite regulated flooding,fracturing and water plugging,plugging and deep regulated flooding and other technologies are also developed.Later,through the demonstration of wet phase modified expansible graphite,new diluent inorganic precipitator,active aging plugging agent,high strength plugging composite materials,combined with the development of the new technology,the oil recovery can be further improved.
