STUDY OF DETERMINING THE ROCK DRILLABILITY WITH SONIC INTERVAL TRANSIT TIME
The paper analyzes the relationship between rock drillability(Kd) and sonic interval transit time(Δt),and creates a computing model of using Δt to determine Kd.The model wis modified with the data of core test and corresponding interval logs in Dongxin region,Shengli Oilfield.The modified model must be a new method to evaluate the formation drillability since its computing accuracy is favourable.
