三叠系特低渗注水开发油藏开发技术对策研究及应用

针对长庆油田三叠系注水开发特低渗油藏存在的主要问题，从分析油田递减规律入手，将低渗储层渗流理论研究方法、数值模拟技术及矿场数理统计方法相结合，分析不同油藏的含水、产量、压力、注水强度等之间的相互关系，最终确定出合理的开发技术时策，确保油田稳产。此项研究时降低低渗透油田递减、提高单井产能、稳油控水有重要意义。

Technical Countermeasures Research and Application of Triassic Ultra-Low Permeability Waterflooding Reservoirs

Aiming at the main issues in extra-low permeability waterflooding reservoirs of Changqing Oilileld Triassic, proceeding from analysis of the law of production diminishing, and combining the low permeability reservoir percolation theory research methods, numerical simulation techniques and mathematical statistical methods, the relationship between the different reservoir water-cut, production rate, pressure, water injection intensity is analyzed, and a reasonable development technical are uhimately determined to ensure the oilfield stable production.
