MUD PULSE TELEMETRY NOISE REDUCTION METHOD |
摘要 |
A method for reducing noise in downhole fluid communications includes processing first and second received signals in combination with a strobe signal from an active pump to obtain pump signatures at first and second spaced measurement locations. The pump signatures are used to compute a transfer function of the fluid channel between the two measurement locations. The transfer function may then be used to estimate the telemetry signal traveling in the uphole direction. |
