| Abstract: | Rock strength of confining pressure is an important index for selecting bit and optimizing drilling parameters,but uniaxial compressive rock strength is very often used to evaluate the parameters,which results in the lack of authenticity and legitimacy in the evaluation.Therefore,this paper analyses the influence factors of the formation permeability on confining pressure and rock-breaking efficiency and makes a classification of the formation permeability.With the rock strength model established based on t... |
| Keywords: | formation permeability bottom hole confining pressure rock strength rate of penetration cluster analysis evaluation methodology |
