Strategic Insights

— 1 min read

Artificial Intelligence (AI) has been applied to reservoir prediction in the Daqing Oilfield, People's Republic of China, enhancing prediction accuracy by 18% compared to traditional methods. A research team from Daqing Oilfield Co. Ltd. has developed a new technique, integrating multi-source heterogeneous data through a deep learning neural network framework, to construct an intelligent reservoir prediction model with geological and physical constraints. This innovative solution has supported new well placement and contributed to a 22% increase in initial oil production in the pilot area.

Key Takeaways:

  • The AI-based technique enhances prediction accuracy for thin sand layers by extracting high-frequency seismic information and establishing robust nonlinear mapping relationships.
  • Inversion errors of reservoir parameters were reduced by more than 25%, while a vertical resolution of 0.5 m was achieved.
  • Predictions agreed with actual drilling data with an accuracy of 86%, representing an 18% improvement over traditional methods.
  • The technique successfully supported new well placement, contributing to a 22% increase in initial oil production in the pilot area.
  • The study establishes a standardized technical procedure: "Time-Depth Modeling-Phase-Controlled Interpolation-Intelligent Inversion."
  • The research has both theoretical significance and practical value for advancing reservoir prediction technology.

Statistics:

  • 25% reduction in inversion errors of reservoir parameters
