APPARATUS FOR PRODUCING HYDRATE GAS

摘要

PURPOSE: A hydrate gas production system is provided to improve the gas collecting efficiency according to the dissociation of a hydrate layer by minimizing the heat loss of hydrothermal water. CONSTITUTION: A hydrate gas production system comprises hydrate production equipment, a first drilling pipe, a second drilling pipe, and a third drilling pipe. The hydrate production equipment collects gases from a hydrate layer under a sea bottom layer. The first drilling pipe has a sea water supply line for supplying sea water from the hydrate production equipment to the upper side of the sea bottom layer. The second drilling pipe is located in the area of the sea bottom layer and has a sea water heating line for heating the sea water from the seat water supply line. The third drilling pipe is located in the area of the hydrate layer and has a hydrothermal water supply line for dissociating part of the hydrate layer with the heated sea water from the sea water heating line.
