GAS HYDRATE EXPLOITATION METHODS UPON TYPES AND OCCURRENCE OF GAS HYDRATE ACCUMULATIONS

Based on the investigation of the present gas hydrate exploitation options, the gas hydrate occurrence in reservoirs and the types of gas hydrate accumulations are summarized. Each proposed gas hydrate production method has both advantages and disadvantages. According to whether the gas hydrate is accumulated in a trap, gas hydrate accumulations are divided into two types. In this paper, the exploitation methods for different types of gas hydrate accumulation are discussed. Suggestions to the future gas hydrate research in China are also put forward.
