优化冲击钻进,特别是凿岩的方法,这个方法使钻进装置调整到理想的钻进结果。依据本发明,测出由冲击在钻杆中产生的应力波,并在测出应力波的基础上调整钻进装置。调整依下列方式进行:阻尼率,或测出的应力波谱,或应力波的波形或其各不同部分的能量。
Optimize impact drilling, especially rock drilling, which allows the drilling unit to adjust to the desired drilling result. According to the present invention, the stress wave generated in the drill pipe by the impact is detected, and the drilling device is adjusted on the basis of the stress wave. The adjustment is made in the following manner: damping rate, or measured stress spectrum, or the waveform of the stress wave or the energy of its various parts.
