齐平5井钻井施工技术

摘要

Well Qp-5,a horizontal exploration well in the Central Depression of Songliao Basin of Qijia Sag,was optimized in well construction and well trajectory profile before drilling along with the appropriate construction BHA,rotary steerable drilling,geology steering drilling to improve the sandstone drilling rate and ensure the operation of drilling.%齐平5井是部署在松辽盆地中央坳陷区齐家凹陷的一口水平探井，在钻井施工前进行了井身结构和井眼轨迹剖面的优化设计，施工中选用合适的钻具组合，应用旋转导向钻井技术、地质导向钻井技术，提高了砂岩的钻遇率，保证了钻井顺利进行。
