摘　　要：为了促进中国石化超深井钻井技术进步,加快深部油气资源勘探开发步伐,在统计、分析钻井数据的基础上,介绍了近年逐步成熟和得以有效应用的气体钻井、"PDC钻头+螺杆钻具"复合钻井、"孕镶金刚石钻头+涡轮钻具"复合钻井、"PDC钻头+扭力冲击器"复合钻井、35MPa高压喷射钻井、自动垂直钻井系统等超深井钻井提速技术。分析了普光气田、元坝气田及塔河油田等中国石化三大重点区域的超深井钻井技术现状:普光气田已钻井平均井深5 999.00m,平均钻井周期232.06d;元坝气田已钻井平均井深7 049.67m,平均钻井周期439.47d;塔河油田12区已钻井平均井深6 441.80m,平均钻井周期102.85d。分析认为,中国石化超深井钻井技术已达较高水平,但与欧美等石油工业发达国家相比尚有差距。最后,对中国石化超深井钻井技术的发展进行了思考,给出了发展建议。In order to promote the progress of ultra-deep well drilling technology, speed up the explora- tion and development of oil and gas in deep reservoir, based on the statistics and analysis of drilling data, this article introduced some advanced technologies that used in ultra-deep wells, including gas drilling tech- nology, composite drilling technology of PDC bit with PDM,impregnated diamond bit with turbodrill,PDC bit with torsional percussion tools, high pressure jet drilling with 35 MPa, automatic vertical drilling sys- tem, etc. The paper also analyzed the technical status of ultra-deep wells drilled in three main oil fields of Sinopec as Puguang Gas Field,Yuanba Gas Field and Tahe Oilfield, the average drilling depth in Puguang was 5999. 00re,average drilling cycle time was 232. 06 days,the average well depth in Yuanba was 7 049.67 m, average drilling cycle time was 439.47 days, average well depth in Tahe was 6 441.80 m, average drilling cycle time was 102.85 days. The analysis showed that the Sinopec ultra-deep drilling technology has been first-class now in the world, but it has some something to do for catching up the advanced technology as that in developed countries in the world. In the end, some thinking and suggestions for ultra-deep drilling technology were proposed in the PaPer.
