近年来,应用“气藏—井筒—地面”一体化模型对常规气藏进行全局性优化配产已逐渐趋于成熟,国内已率先应用于川中M区块D组气藏,取得了良好的经济和社会效益。同时,随着信息技术的不断发展,充分利用“互联网+”的开放性和融合性,突破传统油气勘探开发过程中相对封闭的思维惯性和管理模式,开展智能油气田建设,正逐步成为油气勘探开发提质增效的重要途径。油气田公司以“气藏—井筒—地面”一体化模型为基础,开展智能气田示范工程项目建设,在充分考虑地层能量均衡动用、气藏边底水体能量及水侵量、气井临界条件、地下地面生产设备系统效率的情况下,自动驱动一体化模型进行全局优化配产,形成气藏和单井的配产方案,保障气藏长期稳产,实现气藏资产最大化。研究认为:1)一体化模型的建设与应用,代表了未来油气田分析、管理、组织生产的发展方向;2)通过一体化模型和智能工作流开展产量预测分析,具有较高的预测精度,可大幅度提高研究工作效率;3)智能气田示范工程项目建设成果极具推广价值,有助于油气田公司加快实现“数字化转型、智能化发展”的建设目标。

In recent years, the application of the “gas reservoir-wellbore-surface” integrated model for global optimization and production allocation of conventional gas reservoirs has gradually matured. This technology has been first applied to the D group gas reservoir in the M block of central Sichuan in China, achieving good economic and social benefits. Meanwhile, with the continuous development of information technology, making full use of the openness and integration of “Internet +” has become crucial. This helps break through the relatively closed-minded thinking inertia and management mode in the process of traditional oil and gas exploration and development processes. Implementing intelligent oil and gas field development is gradually becoming an important way to improve the quality and efficiency of oil and gas field exploration and development. Based on the “gas reservoir-wellbore-surface” integrated model, oil and gas companies implemented the intelligent gas field demonstration projects. These projects take into full consideration the balanced utilization of formation energy, the energy and water intrusion of the gas reservoir edge and bottom water bodies, the critical conditions of gas wells, and the efficiency of subsurface and surface production equipment systems. The integrated model is automatically driven for global optimization of production, forming a production allocation plan for gas reservoirs and individual wells, ensuring long-term stable production of gas reservoirs, and maximizing gas reservoir assets. The study concludes that:1)the development and application of “gas reservoir-wellboresurface” integrated model represents the future direction of oil and gas field analysis, management, and production preparation;2)Conducting production forecast analysis through the integrated models and intelligent workflows has high prediction accuracy and can significantly improve research efficiency;3)The implementation achievements of the intelligent gas field demonstration project have great promotional value, which will help oil and gas companies accelerate the realization of their construction goal of “digital transformation and intelligent development”.
