塔河油田水平井完井现状及重点区块完井对策 何祖清 丁士东 赵 旭 岳 慧 庞 伟 （中国石化石油工程技术研究院，北京 100101） 摘 要：为了快速推进“千万吨级”塔河油田建设，西北分公司不论是深化挖潜老区深层油 气藏，还是加快塔河外围区块的勘探开发；不论是面对碳酸盐岩缝洞型主力油藏，还是针对 小断块、低品味碎屑岩油藏，水平井技术无疑仍是塔河进一步提高产量的主流完井技术。为 了满足储层分段改造、分段找水堵水、控水稳油生产需求，以老井侧钻、顺 9 及玉北外围井 区为例提出了分段完井对策及建议，探索了一系列具有较强针对性和实用性的分段完井关键 技术，藉此推进塔河油田高产和水平井分段完井技术的发展。 关键词：碳酸盐岩油藏；碎屑岩油藏；水平井；分段完井；射孔优化；酸化压裂；找水控水 Actual State and Key Blocks Strategy of Horizontal Well Completion in Tahe Oilfield He Zu-qinq Ding Shi-dong Zhao Xu Yue Hui Pang Wei SINOPEC Research Institute of Petroleum Engineering，Beijing 100101, China Abstract: In order to fasten the pace of the construction of “ten million magnitude” Tahe Oilfield, Sinopec Northwest Oilfield Branch has been tapping the potential of mature oilfields’ deeper layers as well as fastening the step of outer zones’ exploration and development. Horizontal well technology is undoubtedly the essential technology to increase oil production not only for fractured carbonate reservoirs but also for fault-block light-grade clastic reservoirs. Strategies and suggestions aimed to Horizontal well segmental completion are proposed taking the old well sidetracking, Shun 9 and Yubei well block as examples in order to meet the need of segmental stimulation, segmental water location water shut-off, and stabilizing oil production under water controlling. A series of key segmental completion technologies which are purpose-aimed and practicable are probed to improve oil well performance and the development of horizontal well segmental completion technology.
