摘　　要：胜利油田济阳页岩油是中石化页岩油开发的重点区块,是我国第三个国家级页岩油开发试验区。该区块地质条件复杂,二开钻井面临着上部砾石层钻头寿命低、行程进尺少,斜井段滑动钻进“托压”严重、钻头攻击性与工具面稳定性矛盾突出等诸多难题。针对以上问题,开展钻井工艺分段优化、井眼轨迹优化、高效钻头及提速工具研制配套等方面的研究,形成了针对胜利油田页岩油Ø311.1 mm大井眼高效钻进工艺技术,该技术在牛庄洼陷应用20口井,提速提效成果显著:与同区块前期相比,机械钻速提高40.8%、平均行程进尺提升46.35%、二开平均钻井周期缩短55.55%,保障了胜利油田国家级页岩油示范区建设的顺利推进。Shengli Jiyang shale oil block is the key development block of Sinopec and the third national shale oil development pilot zone of China,where the geological conditions are complex.Problems exist in the second spud such as shot bit life,less drilling footage,high“supporting pressure”of sliding drilling in the deviated section in the upper gravel layer,and prominent conflict exists between bit aggressivity and tool face stability.In view of the above problems,research was carried out on the optimization of drilling process in sections,optimization of well trajectory,development of efficient bit and matching of speed‑raising tools,etc.,and a high‑efficiency drilling technology forØ311.1mm large hole of Shengli shale oil was formed.The technology was applied in 20 wells of Niuzhuang depression,which achieves significant results in speed‑raising and efficiency improvement.The mechanical penetration rate was increased by 40.8%,the average drilling footage was increased by 46.35%higher than that in the early stage of the same block,and the average drilling cycle of the second spud is shorter by 55.55%compared to that of early stage in the same block,which effectively guarantees the smooth progress of the construction in the national shale oil demonstration area of Shengli Oilfield.
