Research on the Method of Hook Height Measurement Based on Kingview

Abstract

This paper introduces a method of the hook height measurement in drilling process. The mathematical model of hook height is built according to the distributed situation of the wire line. Some relevant parameters of the hook height are acquired by using drawswork sensor, the phase demodulator, ADAM4080 and other components. The software design of the hook height measurement by kingview is given. The error of the hook height is analyzed. The value of the hook height measured is calibrated when the hook is in touch with the drilling platform. The design of the system is simple and flexible. The practical application shows the method running effectively in Tarim Oil Field. So, the method can be widely used in depth measurement.
