Abstract:

Complex wells, with horizontal wells as the basic features, serve as advanced well-type technologies for the efficient development of complicated oil & gas fields with low-permeability, unconventional, marine, and deep features, and they have attracted a lot of attention in China and abroad. This article first introduces the concept of complex wells and their application scenarios. Next, some important developments in directional drilling theories and technologies for complex wells are sorted out, including rotary steerable drilling technology, magnetic steering drilling technology, and extended-reach drilling technology. At last, the challenges in directional drilling of complex wells are analyzed, and the corresponding suggestions are put forward, so as to provide support for directional drilling of complex wells in terms of theoretical and technical innovations.

Key words: oil &, gas well, complex well, directional drilling, rotary steerable drilling, magnetic steering drilling, extended-reach drilling
