随着江苏油田安徽公司钻井技术的不断提高,高难度的深井、预探井越来越多。为了降低钻井周期,节约钻井成本,工程技术中心正式将双扶单弯螺杆钻具组合在各施工区块推广使用,收到效果明显。采用此钻具组合使井眼轨迹更平滑,能够一次性完成增斜、稳斜、扭方位等施工,特别是3000米以上的预探井中的长稳斜段,效果更佳。
With the continuous improvement of drilling technology in Anhui Oilfield Company, Jiangsu, more and more difficult deep wells, more and more pre-exploration wells. In order to reduce the drilling cycle and save the drilling cost, the Engineering Technology Center formally promoted the combination of double-bends bent screw drilling tools to various construction blocks and received obvious results. The combination of drilling tools can make the borehole trajectory smoother, and can accomplish the construction of increasing inclination, stabilizing inclination and twisting position at one time, and especially the long and stable inclined section in the pre-exploratory well above 3000 meters is more effective.
