摘要
有杆泵采油是塔河油田稠油油藏开采的主要方式,随着稠油的持续开发,注水、注气力度的加大,原油黏度增加、含水上升、能量下降,生产中地层出液量及性质剧烈波动,机抽井运行工况日益恶劣,计量极其不准。由于井口参数滞后于井下工况变化,生产中难以提前预防,异常发生后时常错过最佳的优化调整时机,导致断杆、稠油上返、气锁等异常情况频发,严重影响开采效益。为提高机抽井管理水平,基于塔河稠油井筒环境,通过深化远传功图监测技术,提炼了远传功图监测技术在塔河油田的应用情况,并针对稠油计量不准的问题创新性地提出了功图量油的方法。
Rod pump oil production is the main force in the exploitation of heavy oil reservoirs in Tahe oilfield.With the continuous development of heavy oil,the intensity of water injection and gas injection increases.At the same time,both the viscosity of crude oil and the water content increase,and the energy decreases.The formation fluid output and properties fluctuate violently in production.The operating conditions of machine pumped wells are increasingly bad,and the measurement is extremely inaccurate,which makes the management extremely difficult.Because the wellhead parameters lag behind the changes of downhole working conditions,it is difficult to be prevented in advance in production,After the occurrence of anomalies,the best time for optimization and adjustment is often missed,resulting in frequent anomalies such as rod breakage,heavy oil backflow and gas lock,which seriously affects the production efficiency.Based on the understanding of Tahe heavy oil wellbore environment,the application of remote dynamometer monitoring technology in Tahe Oilfield is summarized and refined in this paper by deepening the application of remote dynamometer monitoring technology to improve the management level of mechanical pumping wells.The researcher innovatively puts forward the method of oil measurement of heavy oil well dynamometer to tackle the problem of inaccurate measurement of heavy oil wells.
