摘　　要： 超前注水有利于提高单井产量和油藏最终采收率，本文通过渗流规律、数值模拟和矿场数理统计研究，对超前注水提高低渗透油田的开发效果进行机理分析，提出超前注水期合理地层压力保持水平、注水压力、注水强度、注水时机等开发技术政策，在古云集油田现场推广应用后取得了较好的开发效果，可以提高单井产量15～20％。 Waterflooding in advance is a considerable advantage in increasing the well production rate and ultimate recovery. A series of technologies of development has been put forward in the paper such as a rational pressure maintenance level, injection pressure water intake per unit thickness and suitable injection time during the advanced waterflooding period ,through study of percolation laws ,numerical simulation and field mathematical and physical statistics ,at the same time ,through analysis the theory of developmental effect of advance waterflooding in extra-low permeability reservoirs ,good results＇ of development are obtained by application and widespread of the technology of advance waterflooding to Guyunji Oilfield. The well production rate can be raised by 15-20%.
