大庆油田全周期动态监测技术施策研究

为给大型油气田监测提供借鉴,回顾了大庆油田全周期动态监测技术的发展历程。大庆油田自1960年至2018年底,累计生产原油23.7亿t。大庆油田长期高效开发,与油田重视发展动态监测技术以及开发中充分应用动态监测资料密不可分。围绕油田开发需求,在油田开发试验、快速上产、高产稳产、科学调产、精细挖潜等各个阶段,针对不断变化的技术需求,适时发展相应的动态监测技术,包括水驱和化学驱产出剖面测井和分层注入剖面测井、井身工程状况评价测井、剩余油评价测井等动态监测技术。建立了适应于中国特大砂岩地质体开发方式的动态监测体系,为油田的高效开发予以巨大的支持,成为大庆油田开发经验的重要组成部分。总结了动态监测技术的发展经验,分析了动态监测技术目前面临的形势和挑战,对油田特高含水期动态监测技术的发展方向提出了建议。

Measures of Full Cycle Dynamic Monitoring Technology for Daqing Oilfield

Daqing oilfield was discovered in 1959 and put into development in 1960.By the end of 2018 the cumulative production of crude oil reached 2.37 billion tons.The long-term efficient development of Daqing oilfield was inseparable from its emphasis on the development of monitoring technology and the application of monitoring data in development.The scientific and technological personnel of monitoring system in Daqing oilfield focused on the needs of oilfield development and the corresponding monitoring technology has been developed in view of the changing technical needs in the stages of oilfield development test rapid increase of production high and stable production scientific adjustment of production and fine excavation of extra high water cut.These technologies mainly include the production profile logging and multilayer injection profile logging of medium water flooding and chemical flooding the logging technology for evaluation of wellbore engineering condition and the formation parameter logging.Based on these technologies a monitoring technology system adapted to the geological status and development mode of China’s mega-sandstone has been established in Daqing oilfield which has greatly supported the efficient development of oilfield and become an important part of the development experience of Daqing oilfield.This paper reviews the development history of monitoring technology in Daqing Oilfield summarizes the development experience of monitoring technology and puts forward suggestions on the development direction of monitoring technology in the later stage of high water cut development in Daqing Oilfield so as to serve the sustainable development of Daqing Oilfield and similar old oilfields in China in the whole life cycle.
