本文从白狼城油区的地质概况和开发现状进行了详细描述,该区属三叠系延长组长2油藏属受构造-岩性双重因素控制的复合型油藏,靠弱弹性-弹性驱油,天然能量采收率很低。自开始实施注水开发,日产油量增幅稳步上升,由2006年的0.91t/d增加到2009年的1.81t/d,同时采油速率和采出程度也大幅增大,2007~2009年综合递减连年处于负值区波动。数据表明,采取注水开发,各类指标效果显著。最后,从油藏特征、科学合理的注水开发、动态监测、采油井多向受益、方案的适时调整、管理增效等方面对注水成效的增产因素进行分析。
This paper describes in detail the geology and development status of the Baiyoucheng oilfield, which belongs to the compound reservoirs under the control of tectonic-lithology in Chang 2 reservoir of Triassic Yanchang Formation, and is characterized by weak elastic-elastic Oil displacement, natural energy recovery is very low. Since the commencement of waterflood development, the increase in daily oil production has steadily risen from 0.91 t / d in 2006 to 1.81 t / d in 2009, and the rate of oil recovery and recovery have also increased substantially. From 2007 to 2009, In the negative area fluctuations. Data show that the development of water injection, various indicators of significant results. Finally, the authors analyzed the factors that increase water injection efficiency in terms of reservoir characteristics, scientific and rational waterflood development, dynamic monitoring, multi-directional benefit of oil production wells, timely adjustment of programs and management efficiency.
