RESEARCH ON DRILLING TECHNOLOGY OF BUTT-JOINT WELL

    Graphical Abstract
    • Abstract
  • Considering the geological conditions of Glauber salt depositions at Jie-Cun Shanxi,a trial drilling was conducted to form a butt-joint well.The purpose of the drilling was to use melting mining for a Glauber salt deposit with a depth of 80m and a seam thickness of 3.8m.The maximum tortuosity of butt joint well is 6.27°/m and the maximum hotizontal drilling in the Glauber salt deposit was 70.55m.
