The invention relates to the technical field of drilling experimental simulation, in particular to a simulation and detection system for subsea natural gas hydrate wellhead equipment. The simulation and detection system for the subsea natural gas hydrate wellhead equipment comprises the hydrate wellhead equipment, and also comprises a control system, a material circulation system and a measurementsystem. The simulation and detection system for the subsea natural gas hydrate wellhead equipment solves the technical problems that the simulation of a natural gas hydrate real environment cannot beachieved and the detection of various types of wellhead equipment cannot be adapted in the prior art. Compared with the prior art, the simulation and detection system can simulate the environmental change situation of the natural gas hydrate wellhead equipment under multi-field conditions. The simulation and detection system can simulate heat-fluid-solid coupling conditions, and can determine theinfluence of multiple factors on the natural gas hydrate wellhead equipment under the situation of real confining pressure.
Description
technical field [0001] The invention belongs to the technical field of drilling experiment simulation, and in particular relates to a simulation detection system for an underwater natural gas hydrate wellhead device. Background technique [0002] Gas hydrate is a crystalline structure formed by molecules of natural gas (mostly methane) and water molecules under high pressure and low temperature. And 1 unit volume of natural gas hydrate can release up to 180 unit volumes of methane gas, and the products after complete combustion are water and carbon dioxide, which has almost no pollution to the environment. Natural gas hydrate has huge reserves and is considered to be an important new energy source in the 21st century. According to incomplete estimates, 90% of the ocean is conducive to the formation of hydrate, and its resource volume can reach about 1.8×1016m3. It is more than twice the reserves of traditional oil and gas resources in the world. Some experts predict that i...
