| 摘 要： | 针对钻孔局部壁面应力全解除法地应力测量时,需要在钻孔侧壁上钻切出直径为30mm、长度不小于40mm的微型"悬臂梁"状圆柱形岩样的要求,设计了一套钻切微型圆柱状岩样的室内试验平台。分别以单位时间的钻进深度、钻压、钻头转速作为钻进控制模式,研究了在红砂岩、大理岩、花岗岩3种长方体岩块上钻切微型圆柱状岩样的钻进效果,结果表明,以钻头转速作为钻进控制模式比较理想。定量给出了用于钻孔局部壁面应力全解除岩样切割钻进时的钻头转速、钻压、以及马达功率参数的建议选用范围,从而为开发基于钻孔局部壁面应力解除法的侧壁岩样切割工具提供了参考。

| Abstract: | Several small cylindrical rock samples with a diameter of 30 mm and a length of no less than 40 mm were to be radically drilled surrounding a borehole wall in measuring the rock stresses with borehole-wall stress relief method.For the need of cutting cylindrical rock samples,experimental testing of drilling parameters was made on the self-designed testing equipment at laboratory.Under the conditions of different drilling modes controlled by drilling depth per second,drilling pressure on bit,and rotary speed... |
