摘要:
临古1井是下扬子区中古生界地层的一口重点预探井,设计井深3 200 m。该井在泥盆系和志留系钻遇高研磨性石英砂岩和白云岩,造成钻头寿命短、磨损严重。针对高研磨性地层钻井难点,开展了岩石力学特性分析,优选T1376B型PDC钻头进行个性化设计,钻头进尺提高179%,最高机械钻速2.78 m/h。同时采用自激振荡式旋转冲击钻井技术改善底部钻具组合力学特性,延长钻头使用寿命,同比机械钻速提高36.45%,对高研磨性地层钻井提速有显著效果。
Abstract:
Lingu 1 well is a key exploratory well in Paleozoic formation of Yangtze area,with a design depth of 3 200 m.When drilling in the Silurian and Devonian system,the high abrasiveness quartz sandstone and dolomite were drilled.As a result,there are short life of bit and serious wear-tear.Aiming at the difficulties of high abrasiveness formation,the rock mechanics properties were analyzed,to optimize T1376B type PDC bit and conduct an individual design.As a result,the bit penetration was increased by 179%,and the highest penetration rate was 2.78 m/h.Meanwhile,the self-excited oscillation rotary percussion drilling technology was utilized to improve the mechanical characteristics of bottom hole assembly(BHA)and prolong the service life of the bit.The penetration rate was increased by 36.45%,having a significant effect on improving drilling speed in high abrasiveness formations.
