球卡式绳索取心液动锤的试验研究

Experimental Study on Ball Latch Wire-line Coring Hydro-hammer

摘要:

针对现有SYZX系列绳索取心液动锤中存在的内管总成上浮问题，研制了球卡式绳索取心液动锤，改善了内管总成浮动问题，增大了冲击功输出，进一步提高了钻进效率。室内和生产试验证实，该球卡式绳索取心液动锤钻具原理可行，打捞和定位成功率在95%以上。但在生产实践中还需要对局部细节进行完善。

Abstract:

Ball latch wire-line coring hydro-hammer was developed to solve the inner tube assembly fluctuation of existing SYZX series wire-line coring hydro-hammers, by which, the output impact work is increased with further drilling efficiency improvement. The indoor and production tests confirm that the principle of ball latch wire-line coring hydro-hammer drilling tool is feasible. The fishing and positioning reliability of this hammer are more than 95%, but some partial details still need to be improved in future productive practice.
