Shale gas is a kind of unconventional energy which draws more concern in recent years, so the related exploration and development technologies become the focus. A large quantity of patented technologies has been currently created both in China and abroad. The catalog analysis is made based on the adoption of international patent classification method and using Derent international patent database and Patent database of China intellectual property network, it is found that the patent applications of whole shale gas technologies group are concentrated in 15 technological areas, such as dry distillation and and thermal recovery; while patents of drilling, cementing, well completion and fracturing have accounted very small propotion. But the related patents of these 4 fields are booming quickly. Judging from the life cycle, the shale gas technology is in a period of rapie development and will go to the maturation in 2018. The related upstream fields of drilling, cementing, well completion and fracturing is just entering the rapie development period.
