摘要： A system for transmitting information in a well comprises a tubular string disposed in the well and having a drilling fluid flowing therethrough. A pulser is disposed in the tubular string and transmits a pulse synchronization marker comprising a chirp signal. A surface controller, acting under programmed instructions, detects the chirp signal adjusts a signal decoding technique based on the detected chirp signal.

摘要： A tubular composite member with two ends for connecting ceramic components made of a composite of an inorganic matrix reinforced with inorganic fibers is formed with an at least partially threaded internal surface and an external surface. A ceramic member has at least one surface formed with one or more annular grooves with an inner shell surface, an outer shell surface, and a root. The inner shell surface is at least partially threaded. A resulting ceramic member assembly includes at least two ceramic members connected by at least one tubular composite member. The ends of the tubular composite member are screwed into the corresponding annular groove of two adjacent ceramic members. The such fastened/joined ceramic members can be operated at high temperatures especially under thermal cycling and/or thermal shock conditions as well as dynamic mechanical load in different directions. Methods to manufacture tubular composite members according to this invention are described.
