In the current situation, the imbalance between supply and demand of international energy is increasingly prominent, the exploration and development of shale gas resources becomes the focus of world attention. Shale gas is an ultra-low permeability unconventional gas; there are many key technologies in its exploration and development. The paper introduced the related sealed coring and the hold pressure sealed coring technologies, horizontal well technology and fracturing technology, and put forward the suggestion of developing related technologies for shale gas exploration and development in China.
