Design of LWD borehole depth-measuring device

Graphical Abstract

Abstract

Abstract

In order to solve the problem of LWD depth data, a LWD borehole depth measuring device is developed. The design of the equipment is based on the optical encoder, converts the displacement of the drill pipe into count pulse fed to the CPU to calculate and get the real-time depth data so as to provide support of depth data for processing and interpretation of the logging data.
