8520米!風雷鉆具成功進入亞洲第一深井

發布時間:2019-03-19

  中國兵器工業集團內蒙古第一機械集團有限公司北方風雷公司“金山牌”鉆具繼在中國石化西北局塔里木分公司順北蓬1井順利完成鉆進8450米刷新亞洲最深井記錄后,近日再顯威力,成功完鉆8520米超深井,再一次刷新了亞洲陸上最深井的紀錄。

  深井鉆進難度與風險遠遠高于普通井,對鉆井設備和工具等都提出了更高的要求。一機北方風雷公司在接到訂單后,針對該井地質構造復雜、地層研磨性強、可鉆性差及井底溫度高等施工難點,成立了攻關小組,與用戶共同制定了鉆井技術方案。針對深井鉆進對鉆具產品質量的更高要求,北方風雷公司首次采用偽共析轉變法,將隱晶組織應用在鉆具熱處理工藝中,使材料達到高抗扭和高抗拉的要求。在鉆具螺紋連接方面,公司設計了雙臺肩螺紋,增加了螺紋連接強度,提高了鉆進過程中的安全系數。為保證在鉆井過程中鉆具不出現蹩鉆、跳鉆現象,公司特派技術人員深入鉆井現場進行跟蹤與服務,通過與井隊的密切配合,及時分析地層巖性的鉆具使用情況和不斷優化鉆具使用方案,在鉆進過程中收到了良好效果,得到客戶高度贊揚。連續兩次打破亞洲超深井鉆進記錄,使北方風雷“金山牌”鉆具品牌再一次享譽國內。(黃媛)
