The Study of Structure Design on High Speed Series Wave Mud Pulser System
Zhiming Wang, Xiangfang Li, Guanqi Zhang · Journal of Oil and Gas Technology · 2008
The parameter of logging-while-drilling became more and more in petroleum drilling.It was necessary to develop a high speed series wave mud pulser system for transmitting signal to surface quickly.The theory about series wave power pulse was explained in this paper,the scheme and principle were introduced too.The coding and decoding on the sample were introduced in detail.Quantitative analysis on mud pulser system transmitting signal was carried out.It is considered that the source of the noises to signal,includes electrical interference,mud pump noise,mud motor noise,bit noise,echoes and reflections etc,they are significant in coding and decoding.Reference is provided for developing logging-while-drilling tool.
