详细介绍
ZDQ型水力振荡器是通过自身产生的纵向振动来提高钻进过程中钻压传递的有效性和减少BHA(钻头+马达+扶正器+加重钻杆(钻具)等除了普通钻杆的井底总成)与井眼之间的摩阻,特别是在有螺杆的定向钻进过程中改善钻压的传递,降低摩阻、减少常规钻井卡钻事故,增加动钻压、提高钻井效率。
Model ZDQ hydroscillator improves the effectiveness of bit pressure transmission and frictional resistance between BHA (the pit bottom assembly like drill bit, centering guide, extra-heavy drill rod ( drilling tools) except for ordinary drilling rod in drilling process by the longitudinal vibration generated by itself, especially to improve the drilling pressure transmission with a screw, reduce the frictional resistance, cut down the ordinary drilling sticking accidents, increase the dynamic drilling pressure and improve drilling efficiency in directional drilling process.
