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”.
