Although the drilling rate is related to the structure of the bit, property of the drilling fluid, drilling parameter as well as make-up of string and so on, the theory and practice indicates that the formation factor is the main factor in affecting drilling rate, which not only affects drilling rate directly, but also restrains the influence of drilling parameter on drilling rate.
