摘要: 南川地区是中国石化继涪陵页岩气一期产建区后的又一个页岩气产建区，为进一步促进该地区页岩气水平井钻井提速提效，在借鉴涪陵页岩气一期建设成熟经验的基础上，分析了该地区页岩气水平井钻井存在的技术难点，进行了井身结构优化、个性化高效钻头优选、井眼轨道设计优化、固井完井方式优化和组合钻机“井工厂”钻井模式等方面的技术研究，形成了适合于南川地区的页岩气水平井优快钻井技术。该钻井技术在南川平桥南区块应用了30余口井，平均钻井周期由应用初期的93.00 d缩短至79.67 d，平均优质储层钻遇率达98%以上，其中一趟钻进尺大于1 000 m的井超过60%，提速提质效果良好。在此基础上，分析了焦页10井区和东胜区块的水平井钻井技术难点，提出了技术攻关建议，以期为南川地区后续产能建设中高效钻井提供技术支撑。Abstract: the Nanchuan Area is another shale gas deliverability construction area of Sinopec and it follows the phase I deliverability construction of the Fuling shale gas area. In order to further improve the ROP and drilling efficiency of shale gas horizontal wells in this area, and to take into consideration the mature experiences of the Fuling shale gas phase I project, this paper systematically summarizes the existing problems in drilling the shale gas horizontal wells in this area. An optimized fast drilling technology for shale gas horizontal wells in Nanchuan Area was designed based on the analysis and research on the optimization of casing program, customized high-efficiency bit, wellbore trajectory design, cementing and completion modes, and the multi-well pad construction mode with combined drilling rigs, etc., This drilling technology was applied in more than 30 wells in the South Pingqiao Block of Nanchuan, which shortened the average drilling cycle from 92.00 d to 79.67 d and increased the average encountering rate of high-quality reservoirs to more than 98%. Further, more than 60% of these wells achieved a footage of more than 1,000 m in one trip, proving that the drilling technology could greatly improve the ROP and efficiency. On this basis, taken together with the horizontal well drilling difficulties in the JY10 Well Block and the Dongsheng Block with complex structure, recommendations were made to provide technical support for the subsequent deliverability, construction and efficient drilling in the Nanchuan Area.
