Thermal Exploitation of Gas Hydrate Using Double Vertical Wells Drilling Technology with Long Horizontal Displacement

Abstract:

Gas hydrate was discovered in northern South China Sea by drilling in 2007; and in September of 2009， it was discovered in frozen earth zone of south margin of Qilian Mountain in Tianjun county Qinghai Province. This discovery will play an important role for adjusting energy resources structure and alleviating the energy resource shortage of China. But the exploitation of the gas hydrate and its security are serious problems that are generally interested by the specialists in the world. In this paper, the Russian professors proposed new thermal exploitation technology of gas hydrate using double vertical wells drilling with long horizontal displacement and with heat produced by radioactive (nuclear) waste materials is introduced. This is a patent technology which can be referenced for the study on the exploitation of gas hydrate in China.
