小尺寸无线随钻测量仪器DWD在深侧钻短半径水平井中的应用

Application of Subsize Wireless Directional While Drilling (DWD) Apparatus in Short-radius and Deep Sidetracking Horizontal Wells

针对塔河油田侧钻短半径水平井钻井施工的特点,讨论了小尺寸无线随钻测量仪DWD在这类井的测量施工中的施工难点及应采取的措施。结合T703CH井的实际施工,对DWD在深侧钻短半径水平井中的应用效果进行了分析。DWD在塔河地区深侧钻短半径水平井中的成功应用,为短半径水平井降低施工成本、提高施工效率、回避施工风险找到了一条有效的途径,具有一定的推广应用价值。

In consideration of the characters of short-radius and sidetracking horizontal well drilling in Tahe Oilfield, the difficulties in operation and measures for solving them by using the subsize DWD are discussed. In combination with the actual operation in Well T703CH, the application effect of DWD in short-radius and deep sidetracking horizontal wells is analyzed. The successful application of DWD in the short-radius deep sidetracking of horizontal wells in Taha region provides an effective way for reducing the cost of short radius horizontal well drilling, improving the operation efficiency, eliminating the operational risks, it is worthy to be introduced in oilfields.
