深井超深井钻井技术,是勘探开发深部油气田不可或缺的关键技术。深井超深井钻井技术代表着一个油田的勘探开发技术水平,深井超深井钻井技术的高低优劣,直接影响着一个油田的勘探开发效率和钻探单位在外部市场的竞争力。本文介绍了深井超深井“自上而下”和“自下而上”井身结构设计技术、钻头选型技术和光钻铤大钻压防斜打快技术,希望对深井超深井施工人员具有一定的帮助。
Deep well ultra-deep well drilling technology is an indispensable key technology for exploration and development of deep oil and gas fields. Deep well ultradeep well drilling technology represents the level of exploration and development of an oil field. The performance of deep well ultradeep well drilling technology has a direct impact on the exploration and development efficiency of an oilfield and the competitiveness of drilling units in the external market. This paper introduces the design techniques of deep well ultra-deep wells, top-down wells and bottom-up wells, bit selection technology and large-diameter borehole anti-ramp drilling technology. Construction workers have some help.
