摘　　要：大庆油田经过多年的调整开发,受地层非均质性、井网加密、动态注采开发等影响,已改变了原始井下环境。针对大庆油田异常高压层油水侵、高渗低压层界面胶结质量差两方面难题,以“地质先行,一井一策”为指导思想,开展了钻井地质、水泥浆体系、固井工具等技术攻关,形成注水开采油田调整井固井配套技术。现场应用取得了良好效果,为大庆油田原油产能建设提供井筒保障。After years of adjustment and development,the original underground environment of Daqing Oilfield has changed due to factors such as formation heterogeneity,well network refinement,and dynamic injection production development.In response to the two challenges of oil water invasion in abnormally high-pressure layers and poor bonding quality at high permeability and low-pressure layers in Daqing Oilfield,guided by the principle of geology first and one well with one strategy,technical breakthroughs in drilling geology,cement slurry system,cementing tools,etc.have been carried out,and supporting technologies for adjusting well cementing in water injection and oil production fields have been formed.The on-site application of this technology has achieved good results,providing wellbore support for the construction of crude oil production capacity in Daqing Oilfield.
