【摘要】 针对与深孔钻机相配套的钻进参数检测仪(钻参仪)滞后发展的问题,提出一种适合全液压动力头钻机的全面钻进参数检测方法,并对钻具悬重、钻压、功率、扭矩、孔深、机械钻速、流量等主要钻进参数的检测机理进行了阐述。利用此方法,开发出了一套全液压动力头钻机高精度钻参仪系统,野外应用表明,提出的检测方法切实可行。更多还原

【Abstract】 Aiming at the delayed development of drilling parameter detector for long range drilling rigs,the paper put forward a drilling parameter detection method suitable to drilling by hydraulic top-driving rig,described the de-tection mechanism of the main drilling parameters such as tool weight,weigh on bit,power,torque,hole depth,penetrating rate and flow.Based on the method,a set of drilling parameter detection system for hydraulic top-driving rig has been developed.The results of field application showed that the proposed detection method is feasible.更多还原
