METHOD OF GENERATING DATA PACKETS OF CABLE-FREE TELEMETRIC SYSTEM MEASUREMENTS WHEN WELL-DRILLING

摘要

FIELD: physics. ^ SUBSTANCE: method involves coding each of four data bits using a 16 bit long noise-like signal and transmitting each bit of the coded data using a phase-shift keyed signal. Data is transmitted in blocks containing two types of packets: a conventional packet (Po) S-O1-Z-O2-A-O3-D(K)-O4 and special packets (Ps) S-O1-K1-O2-K2-O3-K3-O4, where K1 is the logging parametre value transmitted over the zenith channel, K2 is the logging parametre value transmitted over the azimuth channel, K3 is the logging parametre value transmitted over an auxiliary channel. ^ EFFECT: increased information content of parametre transmission. ^ 8 cl
