Abstract: Through developing an oil and gas reservoir formation model of the western margin of Junggar Basin, 49.6t/d high-yield industrial oil was obtained in Shawan Formation of Well Pai-2 in Chepaizi District in 2005. And Chunguang Oilfield, a shallow reservoir with high quality, was discovered. Neogene Shawan Formation was its major oil-bearing zone. Based on the need of field production, this paper accurately estimates the choke coefficient of flowing wells in Chunguang Oilfield, providing important basis for implementing single-well production and rational single-well production allocation. It develops a new reservoir development concept taking "real-time dynamic monitoring" as the core, creates a dynamic reservoir monitoring system integrating reservoir, wellbore, and the ground, monitoring the underground oil and water advancement in real time, and provides the means for timely adjusting operation parameters of oil wells and optimizing fluid seepage in strata and wellbore. Oil production in Chunguang Oilfield has been kept growing steadily since 2005, and natural flowing production has maintained since then. Oil production rate and recovery ratio created new high in China.

摘要： 2005年通过创建准噶尔盆地西缘油气成藏模式,在准噶尔盆地西缘车排子地区排2井沙湾组获日产49.6t高产工业油流,发现了以新近系沙湾组为主力含油层的浅层优质春光油田。基于生产的需要,准确估算了春光油田自喷井油嘴系数,为落实单井产量及单井合理配产提供了重要依据;发展形成了以"实时动态监控"为核心的油藏开发新理念,创建了油藏、井筒、地面三位一体的油藏动态监控体系,实时监控了地下油水推进的状态,为及时调整油井运行参数、使地层及井筒中的流体运移达到最优化状态提供了手段。春光油田自2005年开发以来产量稳步上升,保持自喷开采,采油速度、采收率同创国内新水平。
