| 摘 要： | 广金6-2 HF井是川西采气厂在蓬莱镇组气藏首次应用随钻地质导向钻井技术完成的一口长水平段水平井。该井利用随钻地质导向技术及综合录井技术，优选钻具组合，精确控制井眼轨迹，准确卡住目的层砂顶以及A靶垂深，实现A靶精确着陆。单弯双扶钻具组合在蓬莱镇气藏具有良好的稳斜效果，该井水平段进尺为980.84 m，其中滑动钻进进尺为21.5 m，复合钻进进尺为959.34 m，复合钻进比例为97.8％，大大提高了钻井效率。岩屑录井显示，水平段钻遇泥岩4 m，泥质粉砂岩8 m，细粒岩屑砂岩968.84 m，储层钻遇率为98.8％。该井完钻后没有测井，利用地质导向资料及录井资料确定射孔位置，从而缩短了钻井周期，降低钻井成本。

| Abstract: | Guangjin 6-2HF is a long extension horizontal well of Chuanxi gas production plant, which was first finished by using geo-steering drilling technique in Penglaizhen gas reservoirs.The well trajectory was accurately controlled by geo-steering drilling technique and comprehensive logging technique with BHA optimization, target A landed accurately.The BHA with single bend screw and double-stabilizer had a good steady inclination effect in Penglaizhen gas reservoirs.The to-tal footage of the horizontal section of this well was 980.84 m, including 21.5m sliding drilling footage and 959.34m com-plex drilling footage.The complex drilling ratio was 97.8%, which greatly improved the drilling efficiency.The successful experience of this well provided a good basis for the application of geo-steering drilling technique in Chuanxi area. |
