A Method for Logging Speed Correction in Modern Diplog

The diplog tool (1016 type) has been imported recently and put into application in many oilfields. The SHDT(Schlumberger)which has, more or less, similar characteristics and functions, is in wide use over our country. Compared with the earlier types, these tools are improved in data acquisition and measurement accuracy. A new inclinometer system of three-dimensional accelerometer and three-vector magnetometer ensures a high accuracy of orientation measurement and implementation of speed correction for correlation curves. This paper provides an overview of the inclinometer section and orientation data computation method for modern diplog instruments. The speed correction and the error analysis is discussed in this paper. Finally. the applicability of the speed correction method and three-D or one-D accelerometer to other logging tools is analysed.
