大庆油田套损井评价技术研究

Study on Evaluation of Casing Damage Wells in Daqing Oilfield

依托套损井综合管理平台,经过长期探索和技术实践,建立了油田相应的套损井分析模式,从工程服务的视野,结合异常井信息,对油田套损井和成片套损区域,从历史、构造、开发经历、时空和井网等进行分析,探索套损井产生的根源。对油田套损井预防和管理提出建议,达到减少新增套损井和重复套损的目的,适应油田长远发展对套损井管理的要求。

An analysis mode of casing damage wells in Daqing Oilfield is established based on the integrated management platform of casing damage wells. Based on the purpose of engineering service, the causes leading to the casing damage are analyzed from the his- tory, geologic structure, development experience, time and space, and well patterns of the regions with a lot of casing damage wells, and some suggestions for the prevention and management of casing damage wells are proposed to prevent the generation of new casing damage wells and the repeated damage of old casing damage wells and to adapt to the requirements of oilfield long-term development to the management of casing damage wells.
