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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Natural gas hydrate formation drilling simulation device","description":"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.
