Abstract:Downhole pressure receiver is one device to study the attenuation and the anti-jamming capability of negative pulse about drilling fluid in the process of passing downward.Based on the analysis of circuit design about the device,the paper introduces the basic principle and the selection of components.Meanwhile,according to some main factors affecting pulse signals greatly,such as the well depth,the way of signal transfer,the pump pressure,and the pulse amplitude,the circuit design of this device has been ap...
Keywords:pressure signal  transferring signals downward  data collection
