摘　　要：注水井调剖技术作为一种有效的提高采收率方式在坪北油田得到了广泛的应用,近年来在坪北油田的调剖施工次数呈逐年增多的趋势。在对坪北油田推广应用的两种调剖工艺技术进行对比分析的基础上,从调剖后的增油、注水压力变化、有效期、单井成本等方面进行了综合分析。提出了坪北油田的下一步调剖思路,为低渗透裂缝性油藏后期的稳油控水提供了技术支持。Profile control of water injection has been widely used as an effective way of raising recovery ratio in Pingbei Oil Field where the conduction of profile control is on the yearly increase.Based on the comparison of the two profile control methods that are employed in Pingbei,this paper makes a comprehensive analysis on every aspect from production increasing to water flooding pressure change and valid date and onto the costs of single well operation.In this paper,the further development of profile control in Pingbei Oil Field has been pointed out to provide technical support for stable production and water cut control at the later developing phase of the fractured reservoirs of low permeability.
