| 中文摘要:隆平1井是大庆油田首口在沉积盆地基底层施工的水平井，设计斜深4532.72 m（垂深3111.50 m），勘探钻井目的是为了探索通过水平井大幅度提高古中央隆起带基岩风化壳储层天然气产能。针对该井在钻井过程中可能遇到的难点与风险，进行了井身结构优化设计、井眼轨道优化设计、钻井参数优化、钻头优选及配套提速试验等。实钻情况表明，该井全井平均机械钻速5.15 m/h，相比设计钻速提高45.89%，现场施工提速效果明显，为探索该区域基底构造提供了宝贵的经验。 |

| Abstract:Well Longping-1 is the first horizontal well drilled in the bedrock formation of Songliao Basin in Daqing Oilfield. The designed MD is 4532.72m (TVD: 3111.50m). The exploration purpose of the well is to explore how to greatly improve the natural gas productivity of the weathered crust bedrock reservoir in the ancient central uplift zone through horizontal wells. In order to tackle the potential difficulties and risks in the process of drilling, optimization was performed of well structure design, well trajectory design, drilling parameters, and bit selection with the ROP enhancement experiments. The full well average ROP was 5.15m/h with an significant increase by 45.89% compared with the designed value, which provides valuable experience for exploring the basal structure in this area. |
