Abstract: As an important part of LWD process, data transmission technology not only provides the basis for real-time processing and analysis of the downhole geological and geophysical information but also helps improve the efficiency and economic performance of oil and gas exploration and development. Currently, the widely-used LWD data transmission technology includes mud pulse transmission, electromagnetic transmission, acoustic transmission and wired pipe. The different technologies have their own advantages and disadvantages. This paper elaborates the new progress made in LWD data transmission technology, such as DigiScope from Schlumberger, EM Casing Link and XACT AT from Weatherford, and Intelliserv from NOV. It also briefs about the related application results on the basis of service cases, providing references for rapid development of China’s LWD data transmission technology.

Key words: LWD, data transmission, mud pulse, electromagnetic, acoustic wave, wired pipe
