FORMATION PRESSURE ESTIMATED BY INTERVAL TRANSIT TIME OF MUDSTONES

One of important jobs in the designing of oilfield drilling is to predict the formation pressure. The paper describes in detail the fundamental principles based on which to estimate formation pressure by applying interval transit time. Meanwhile,the authors compiles technical softwares with the basis of the principles. It is considered that this method is characteristic of a high accuracy,easy operation and profounding significance in the development and application within the oilfield.
