使用可以加载钻压的试验设备，在不同钻压、切削面积、切削速度和切削齿后倾角条件下对不同性质的岩石进行钻进试验，通过对试验数据的多元非线性回归分析，建立新的PDC切削齿与岩石相互作用模型。结果表明：切削面积是影响切削齿受力的主要因素；切削齿受力随切削面积、切削齿后倾角和岩石可钻性级值的增大而增大；切削齿受力与切削速度呈对数关系。

A series Of drilling experiment were carried Out by using experimental equipment, in which lOad On cutters can be increased. Experiments were cOnducted with variOus lOad, cutting area, cutting speed, back dip angle Of PDC cutter and rOck prOperties. The experimental results were analyzed with multiple nOnlinear regressiOn technique and a new cutter-rOck interactiOn mOdel was prOpOsed. The results shOw that the cutter area is the principal factOr influencing the fOrce Of cutters. The fOrce Of cutters increases with cutting area, back dip angle Of PDC cutter and rOck drillability. It is a lOgarithmic rela-tiOnship between the fOrce Of cutters and cutting speed.
