摘　　要：为解决胜利西部探区哈山地区中深层石炭系、二叠系坚硬地层可钻性差、地层倾角大、井斜难控制、井壁易失稳等技术难题,实现油气储量的高效勘探、效益开发,在现用常规钻井技术的基础上,通过分段组合钻井技术适用性研究与工艺优化,针对石炭系、二叠系的云质岩、火成岩难钻地层,提出气体钻井相关提速及安全施工配套技术,形成了地区施工规范;在气体钻井转钻井液施工后,优先选用“气体钻井+‘孕镶钻头+涡轮钻具/高速螺杆’”组合钻井技术,并针对地层特点研发了不同尺寸的高效孕镶钻头系列,实现井斜控制与机械钻速双提高。该组合钻井技术在哈山3和哈山2等井成功应用,取得了良好的效果,其中哈山3井气体钻井机械钻速达到5.2m/h,较常规钻井方式提速3倍以上,转钻井液施工后采用孕镶钻头+涡轮钻具/高速螺杆施工,地层倾角为30°,井斜控制良好,机械钻速接近1m/h,较常规钻井技术表现出良好的区域应用效果。现场应用表明,“气体钻井+‘孕镶钻头+涡轮钻具/高速螺杆’”组合钻井技术是实现胜利西部探区哈山地区中深层钻井提速提效的一种有效手段,但该组合钻井技术也存在瓶颈,结合对粒子冲击钻井技术的适用性研究,建议下步引进并完善粒子冲击钻井技术,力争实现区域钻井提速提效再突破。This paper aims to solve the technical problems such as poor drillability,large formation inclination,difficult well deflection control,and easy wall instability in the middle and deep Carboniferous and Permian hard formation in the Hashan area of Shengli western exploration area and realize the efficient exploration and benefit development of oil and gas reserves.Based on the current conventional drilling technology,the applicability and process optimization of segmented combined drilling technology were studied,and supporting technologies for speed acceleration and safety construction related to gas drilling were proposed for the Carboniferous and Permian hard formation of dolomitic rock and igneous rock,forming the regional construction standards.After the transformation from gas drilling to drilling fluid construction,the combined drilling technology of“gas drilling+‘impregnated bit+turbine/high-speed screw’”was preferred.According to the formation characteristics,efficient impregnated bit series of different sizes were developed to achieve well deflection control and improve the rate of penetration.The combined drilling technology was successfully applied in Hashan3 and Hashan2 wells and achieved good results.During gas drilling,the rate of penetration in Well Hashan3 reached 5.2 m/h,more than three times faster than the conventional drilling method.During drilling fluid construc‐tion,the technology of“impregnated bit+turbine/high-speed screw”was adopted,and the formation inclination was 30°.The well deflection was well controlled,and the rate of penetration was close to 1 m/h,which showed a good regional application effect com‐pared with conventional drilling technology.The field application shows that the combined drilling technology of“gas drilling+‘impregnated bit+turbine/high-speed screw’”is an effective means to increase the speed and efficiency of middle and deep drilling in the Hashan area of Shengli west exploration area.However,the technology also has bottlenecks.Combined w
