PENETRATION RATE PREDICTION WITH SONIC LOGGING DATA

-
Abstract
The paper discusses the relationship between sonic logging and petrophysical property,points out the basic factor affecting penetration rate-formation factor,through the typical penetration rate mode.Since sonic logging data reflect of formation factor,it could be used to predict penetration rate.By analyzing the results of the tests,a penetration rate mode is derivated.The mode could be modified upon field drilling conditions and casing programme.
