New Development of Permeability Profile Modifi-ca tion Tech nique During the 'Ninth Five Year Plan' in Huabei Oilfield

摘要: 对中国石油华北油田公司“九五”期间堵水调剖技术的堵调剂种类、应用状况、调水增油效果以及堵水调剖技术的新发展进行了总结论述。现场实践表明,堵水调剖技术是改善油藏内部裂缝系统和孔隙介质的油水渗流状况,提高油井产量和油藏开发水平必不可少的重要措施之一。尤其在油田开发后期,该项技术更具有强大的生命力。

Abstract: This paper summarizes the types,application and effects of water shutoff agents and the new development of permeability profile modification technique in Huabei Oilfield Company of CNPC.Field application show that water plugging profile modification technique is effective in improving fracture system in reservoirs and oil and water seepage flow in porous medium and in increasing oil output.This technique is especially useful at the late development stage of an oilfield.
