Directional Technology of Shale Gas Horizontal Wells in Fuling Area

Abstract:

As the first national shale gas demonstration area, Fuling shale gas productivity demonstration area was started in 2012. Through continuous technological research and innovation, a perfect domestic horizontal well drilling technology series has been formed. With blocks transfer in 2015, the geological conditions became more complex, new technical difficulties were encountered in directional construction. On the basis of the existing mature technologies, by the technology optimization and the application of advanced friction and torsion reducing tools, the construction difficulties in new blocks have been effectively solved, which promotes the construction of shale gas productivity zone.
