【摘要】："十二五"期间,为解决塔里木、四川等盆地超深油气藏勘探开发所遇到的深井超深井钻完井难题,中石油研制了一批具有自主知识产权的重大装备、工具、仪器、工作液等,包括:①8 000 m钻机、四单根立柱超深井钻机、5 000/7 000 m钻机管柱自动化处理装置、精细控压钻井技术与装备、双燃料/高可靠性钻机动力机组、气体/欠平衡钻井装备等6项深井超深井核心装备;②自动垂直钻井工具、涡轮钻具、高效PDC钻头、系列复合钻头、水力脉冲提速工具、钻井井下安全监控系统、顶驱下套管装置等7项核心工具;③高温高密度水基钻井液、油基钻井液、高温大温差固井水泥浆、韧性水泥浆体系等4项钻井液和水泥浆体系。研究认为,"十三五"期间深井超深井钻完井所面临的挑战包括:深井超深井高温、高压、窄密度窗口、井筒完整性等,以及降本增效的巨大压力,亟待在深井超深井高效运移钻机、高效破岩钻头和辅助工具、井筒完整性、井下宽带信息传输技术等方面开展攻关并力争取得技术突破。结论认为:上述研究和试验成果有力地提升了中石油超深井钻完井的能力和水平,将对中石油油气勘探开发业务起到重要的支撑作用。
[Abstract]:During the 12th Five-Year Plan period, in order to solve the problems encountered in the exploration and development of ultra-deep oil and gas reservoirs in Tarim and Sichuan basins, PetroChina developed a number of major equipment, tools, instruments and working fluids with independent intellectual property rights. Including: 18000 m drill rig, 4 single vertical pillar ultra-deep drilling rig, 5 000 / 7 000 m drill string automatic processing device, fine pressure control drilling technology and equipment, dual fuel / high reliability rig power unit, Gas / underbalanced drilling equipment, etc., 6 items of deep well ultra-deep core equipment, such as automatic vertical drilling tool, turbo drilling tool, high efficiency PDC bit, series of composite bit, hydraulic pulse speed raising tool, drilling downhole safety monitoring system, High temperature and high density water-based drilling fluid, oil based drilling fluid, high temperature and large temperature difference cementing cement slurry, etc. Four items of drilling fluid and cement slurry system, such as ductile cement slurry system, are studied. It is considered that during the 13th Five-Year Plan period, the challenges faced by deep and ultra-deep well drilling and completion include: high temperature, high pressure, narrow density window, wellbore integrity, etc. As well as the huge pressure of reducing cost and increasing efficiency, it is urgent to have a high efficiency migration rig, high efficiency rock breaking bits and auxiliary tools, and wellbore integrity in deep and ultra-deep wells. It is concluded that the above research and test results have powerfully improved the ability and level of CNPC ultra-deep well drilling and completion. Will play an important role in CNPC oil and gas exploration and development business.
