摘　　要：针对川东北分水岭构造须家河组地层段机械钻速慢的钻井难题,开展了提速技术研究。首先通过工程地质特征分析,获取了须家河组地层矿物组分含量和岩石力学参数,并有针对性地提出提速技术思路和提速手段。从分3井现场应用效果看,气体钻井技术、螺杆钻具+混合钻头以及扭冲工具+混合钻头钻井技术均取得不同程度的提速效果,其中气体钻井技术平均机械钻速最高,达到4.78m/h,与同井采用常规泥浆钻井相比提高4.49倍。In order to solve the problem of low drilling rate in Xujiahe formation of Fenshuiling structure in northeast Sichuan,study has been carried out to improve drilling rates.First,the mineral components and rock mechanics parameters in Xujiahe formation have been obtained through analysis of the engineering geological characteristics.Then,the technical route and measures for speeding up drilling rates in Xujiahe formation have been specifically analyzed and discussed.Applications in F 3 well have demonstrated that drilling rates increased in different degrees with use of gas drilling and the combined drilling of screw tool+hybrid bit and torsional impact tool+hybrid bit.Meanwhile,the highest average rate of penetration with gas drilling reached 4.78m/h,and increased by 4.49 times compared with conventional drilling.
