Tacan 1 well (called TC1 for short) is an exploration well in the central part of Tarim Basin, NW China and also the deepest on-land well in China so far. The strata revealed by this well covers upper to lower are Quaternary, Neogene-Eogene (without further classification), Cretaceous, Triassic, Permian, Carboniferous, Devonian, Silurian, Ordovician, Cambrian and Precambrian granodiorite. The stratigraphic section is relatively complete has systematically extracted cores. It is very precious for geological study In Tarim. This paper provides its brief description. Some related problems are discussed.
