油田开发过程中，油藏层间、平面矛盾加剧，注采动态调整频率加快、剩余油挖潜难度加大等问题亟待解决，提升测调效率和建立动态数据库是为有效手段，即为油藏数字化、智能化的雏形。其中，油水井井筒数字化、智能化作为智慧油田发展的关键一环，一方面为油藏工程提供实时、准确的油层动静态数据，为地面工程提供流体的实时状态，满足数字化开发需求；另一方面能够根据数据库自动、智能改变油层状况，实现动态调整，满足开发动态调整需求。围绕高精度传感器、有线/无线通信、信号处理等现代科学技术，对大庆油田智能油水井井下工具功能、原理及核心技术进行归纳剖析，形成油水井数字化井筒技术的现状论述，结合油水井井筒结构设计、生产参数获取等生产需求，提出一种油水井井筒数智化构建设想和发展雏形，为未来行业形成完整、全面的井筒构建理论提供指导。

Along with the progress of oilfield development, the plane and inter-layer contradictions gradually intensify, the frequency of dynamic adjustment for injection and production accelerates, and tapping the potential of remaining oil becomes more difficult. These problems need to be solved urgently. To solve these problems, improving the measurement and adjustment efficiency and establishing a dynamic database are effective means, that is, the prototype of reservoir digitization and intelligentize. The digitization and intelligentize of wellbore for oil and water wells is a key part of developing smart oilfields. On the one hand, it provides real-time and accurate oil layer dynamic and static data for reservoir engineering, and provides real-time fluid status for surface engineering, which will meet the needs of digital development; on the other hand, it can automatically and intelligently change the oil layer status according to the database, and realize dynamic adjustment, which will meet the needs of dynamic adjustment of development. Focusing on modern science and technologies such as high-precision sensors, wired/wireless communication, signal processing, etc., the function, principle, and core technology of downhole tools for intelligent oil and water wells in Daqing Oilfield were summarized and analyzed, and the status quo of digital well technology for oil and water wells was discussed. Combined with the production requirements such as well structure design and production parameter acquisition for oil and water wells, a vision and development prototype for constructing digital-intelligence well foe oil and water wells was proposed, which may provide a guidance in forming a complete and comprehensive well construction theory for future industry.
