新型抽吸式绳索取心液动锤钻具的初步设计

Preliminary design of a new type of suction rope coring drilling tool

在绳索取心液动锤钻具的基础上,结合其工作原理,在内管总成上增加喷射式抽吸总成,并设计相应的底喷式阶梯钻头,初步设计形成了新型抽吸式绳索取心液动锤钻具,用于解决深孔复杂地层采取率低的问题。

Based on wire line coring hydro hammer on, with its working principle, the inner tube assembly, add ejector suction assembly, and the design of bottom jet bit corresponding to the preliminary design to form a new type of suction type rope coring hydro hammer, to solve the deep hole complex formation take the problem of low rate.
