松辽盆地北部芳198-133区块致密油地质工程一体化压裂实践
|
摘要
大庆油田致密油储层分布广泛,资源潜力巨大,为促进大庆油田致密油藏的有效开发,探索了地质工程一体化的压裂施工模式。以提质增效为核心,通过平台井压裂方案的整体优化,将地质、钻井、压裂、作业施工紧密结合,实现了致密油储层改造规模最大化。采用集约型的工厂化施工方式,现场用工人数缩至26人,占地面积节约77%,利用一套车组完成芳198-133区块9口水平井154段压裂施工,用时仅32天,大幅提升了施工时效;通过该区块的探索应用,形成了一套具有大庆特色的工厂化压裂施工标准。芳198-133区块经过改造后,生产158天,累计产油1.55×10~4m~3,单井平均日产油38.1m~3,相比同区直井措施产量提升14倍,达到了预期的增产效果。通过增能提效,使综合施工成本降低36%,实现了试验区致密油藏整体动用和经济有效开发,对大庆油田其他致密油区块增产改造具有重要的指导和借鉴意义。
Tight oil reservoirs are widely distributed and have a huge resource potential in the Daqing oilfield. For effective development of such tight oil reservoirs, the fracturing stimulation based on geology-engineering integration was proposed. Specifically, the pad-based fracturing scheme was optimized to combine geologic, drilling and fracturing data with operation procedures, maximizing the stimulated reservoir volume. Following an intensive factory-like operation mode, the number of field staff was reduced to 26, and the covering area was saved by 77%. With one package of fracturing truck, the fracturing operation was completed in 154 stages of 9 horizontal wells in Block Fang198-133 within 32 days. Accordingly, a set of specific factory-like fracturing specification for Daqing oilfield was established. As a result,1.55×10~4 m~3 of oil or 38.1 m~3 per well per day has been produced during 158 days after fracturing stimulation, which is 14 times higher than the vertical well stimulated in the block. With the increase of productivity and efficiency, the comprehensive operating cost was reduced by 36%.Thus, the tight oil reservoirs in the block were fully recovered and developed economically and effectively. And the practices are significant to the production improving of tight oil reservoirs in other blocks of Daqing oilfield.
