大港油田目前针对低渗透储层主要采用大斜度井、水平井分段压裂完井工艺,主要包括:水力喷砂射孔分段压裂完井、套管固井滑套分段压裂完井、多簇射孔分段压裂完井、Opti-packer连续油管无限级滑套分段压裂完井。通过水平井分段压裂完井工艺现场应用实践,取得了较好的实施效果。引进的先进技术实施提升了大港油田特殊工艺井完井的整体技术水平,但有些工艺技术的适应性还有待提高。本文针对水平井不动管柱水力喷射分段压裂完井工艺展开研究并进行了现场应用。
At present, Dagang Oilfield mainly adopts high-deviated wells and horizontal well-section fracturing completion technologies for low-permeability reservoirs, mainly including hydraulic sandblasting perforation fracturing completion, casing consolidation casing slip fracturing Completion, multi-cluster perforating fracturing Completion, Opti-packer coiled tubing Infinite-grade casing Segmented fracturing Completion. Through field application practice of horizontal well fracturing and completion technology, good implementation effect has been achieved. The introduction of advanced technology to enhance the completion of special wells in Dagang Oilfield overall technical level, but some of the adaptability of technology needs to be improved. In this paper, horizontal well hydraulic propulsion fracturing completion of the well to carry out research and field applications.
