The invention provides an intelligent drilling
expert system. The intelligent drilling
expert system comprises a field sensor detection
system, an intelligent
expert system and an execution mechanism. An automatic closed-loop drilling regulation and
control system is formed. Data in a whole drilling process are acquired through a field sensor; then, the acquired data are transmitted into a computer for
processing, monitoring, prediction, analysis, explanation, control and the like. Most importantly, through the researched cross-
specialty and cross-industry intelligent expert
control models for drilling
hydraulic control, well wall stability control, friction resistance and torque control, drilling speed and
cost control, drilling complexity and accident control and the like, instantaneity, early discovery,
early prediction, interpretation while drilling and an
automatic control function can be realized, and accurate information is provided for
drilling engineering; moreover, the intelligent drilling expert
system has the advantages of reducing the drilling cost, increasing the drilling speed, avoiding sudden accidents and discovering oil and gas accurately.
