Abstract: During the 12th Five-year Plan period, CNPC launched important surface engineering technological research projects, aiming to transform oil and gas development patterns, satisfy the development and production demand for steamflooded heavy oil fields, high-acidic gas fields and coal-bed methane. Therefore, it has developed a series of technologies, such as surface process for steam-flooded heavy oil production, cost-effective heavy oil development, simplification of condensate gas field, safety of high-acidic gas field development, and mixed transportation of oil and gas. In addition, a series of standards, specifications and technological instructions were formulated to technically support CNPC in its efforts to accelerate natural gas business and stabilize crude oil production while providing the company with the benchmarking basis and development strategy for further improvement of performance in the surface engineering area. The technological system, established in the research projects and used in production, supported the new oil and gas development patterns, reduced investment and operational expense, partly solved safety and environmental issues, and improved the creativeness of professionals in their technological research efforts. The study points out that the future surface engineering technology will develop in the direction of “closed and highly-efficient process, cost-effective and low energy consumption, and intelligent and reliable safety and environmental protection.”
