Natural gas hydrate formation drilling simulation device
A natural gas hydrate drilling simulation device, includes a hydrate rock core simulation system, a drilling system, a drilling fluid injection system and a drilling fluid treatment system. The hydrate rock core simulation system includes a hydrate formation simulation wellbore, an artificial rock core, a water bath jacket and low temperature water bath. The drilling system includes a bracket, a high pressure rotary connecting device, a hydraulic device and a drilling device. The drilling fluid injection system includes a mud tank, a drilling fluid flowmeter, mud pumps and an overflow valve. The drilling fluid treatment system includes a high pressure sand remover, a back pressure and overflow control system, a gas-liquid separator, a dyer, a gas flowmeter, a liquid flowmeter and a mud treatment tank. This natural gas hydrate drilling simulation device performs simulation experiments under a variety of downhole working condition environments.
