摘要
高升油田为典型的中深厚层块状普通稠油油藏,针对其进入蒸汽吞吐开发末期开发效果差的情况,先后在高3618块和高3块开展火烧油层现场试验,并逐步扩大至目前39个井组规模。火烧油层现场实施过程中,严格把握点火注气、动态分析、跟踪调控、动态监测等关键环节,并不断改进完善,实现了火烧井全部一次点火成功,典型井组处于高温氧化燃烧状态,日产油上升2.8倍。火烧油层过程控制技术可为其他同类型油藏开发提供借鉴。
Gaosheng oilfield is a typical deep massive heavy oil reservoir,for entering the steam soak exploitation stage,development effect is poor.In order to improve the development effect,the field tests of in situ combustion were done in Gao 3618 and Gao 3 block,and gradually expanded to the current 35 well groups.During the in situ combustion,the ignition gas injection,dynamic analysis,dynamic monitoring,tracking control etc.were improve and perfect constantly,and the primary ignition success ratio of all fire flood wells was 100%.The typical well group in high temperature oxidation combustion state,daily oil production increased 2.8 times,the in situ combustion process control technology provided reference for other same type reservoir development.
