The fluid distribution and flowing states in a wellbore annulus are analyzed in real time, and during a measured standpipe pressure deviation design, a pressure control value is calculated accurately in consideration of the effects of a pressure wave propagation speed and a back pressure application delay, and a throttle valve is automatically adjusted and automatically controlled to actuate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Intelligent throttled well-killing method and device for overflow in high-temperature and high-pressure deep drilling","description":"In view of the problems of complex downhole conditions, low control precision of bottomhole pressure, low one-time success rate of well-killing and the like during a high-temperature and high-pressure","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11512542","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
