摘要

通过对“十三五”以来国外页岩油气储集层水平井压裂技术进展的系统总结,阐述了水平井压裂技术在页岩油气储集层多层叠置立体开发、小井距密井网布井、水平井重复压裂、施工参数优化与降低成本方面的新特征;结合中国页岩油气水平井压裂技术需求,论述了水平井压裂技术在多裂缝扩展模拟、水平井压裂设计、电驱压裂装备、可溶化系列工具、低成本入井材料与工厂化作业方面的新进展。在此基础上,结合非常规页岩油气“十四五”规划对水平井压裂改造技术的需求分析,提出了7个方面的发展建议：①强化地质工程一体化联合研究;②深化页岩储集层改造基础理论及优化设计技术研究;③完善大功率电驱压裂装备;④研发长井段水平井压裂工具及配套作业装备;⑤加强水平井柔性开窗侧钻剩余油挖潜技术攻关;⑥发展长井段水平井压裂后修井作业技术;⑦超前储备智能化压裂技术。

Abstract

By systematically summarizing horizontal well fracturing technology abroad for shale oil and gas reservoirs since the "13th Five-Year Plan", this article elaborates new horizontal well fracturing features in 3D development of stacked shale reservoirs, small well spacing and dense well pattern, horizontal well re-fracturing, fracturing parameters optimization and cost control. In light of requirements on horizontal well fracturing technology in China, we have summarized the technological progress in simulation of multi-fracture propagation, horizontal well frac-design, electric-drive fracturing equipment, soluble tools and low-cost downhole materials and factory-like operation. On this basis, combined with the demand analysis of horizontal well fracturing technology in the "14th Five-Year Plan" for unconventional shale oil and gas, we suggest strengthening the research and development in the following 7 aspects: (1) geology-engineering integration; (2) basic theory and design optimization of fracturing for shale oil and gas reservoirs; (3) development of high-power electric-drive fracturing equipment; (4) fracturing tool and supporting equipment for long horizontal section; (5) horizontal well flexible-sidetracking drilling technology for tapping remaining oil; (6) post-frac workover technology for long horizontal well; (7) intelligent fracturing technology.

Key words： shale oil and gas; horizontal well fracturing; fracturing equipment; fracturing parameter; three-dimensional development; intelligent fracturing
