Research on LWD Transmit Circuit Based on DDS Technology

Abstract:

A new type of logging transmit circuit applied to measurement while drilling (MWD) based on DDS technology is presented. As for logging instrument, Electromagnetic wave source is very important .The logging transmit circuit adopts TMS320VC33 series digital signal processing chip as main controller, in addition, LWD(logging while drilling) signal waveform generation circuit, peripheral signal processing circuit, DDS module, DSP and AD9850 interfaces, etc have been given.2MHz and 400KHz digital transmit circuit mainly composed of DDS AD9850 , which carries out the shift of the phase and the limit of the amplitude easily ,has been designed and debugged successfully. it is used to substitute for the conventional transmit circuit ，so the all-digital transmit channel of phase shift is achieved. The experimental results show that the logging transmit circuit for MWD is feasible.
