METHOD OF DETERMINING BOREHOLE CONDITIONS FROM DISTRIBUTED MEASUREMENT DATA

摘要

Methods of determining borehole conditions using distributed measurement data are disclosed herein. The disclosed methods utilize real time data measurements taken from sensors (151) distributed along the length of a drill string(109) to assess various conditions or properties of the borehole (101). In particular, the distributed data may be used for example, to track the progress of a chemical pill or also track the location of different types of borehole fluids, and also to determine the hole size or volume of the borehole.
