Keywords: Áp suất nứt vỉa, ANN, bể Nam Côn Sơn

Tóm tắt

Dự báo áp suất nứt vỉa là công việc quan trọng khi lên kế hoạch thiết kế giếng khoan, cho phép kiểm soát, vận hành, kích thích giếng hoạt động hiệu quả. Nếu dự báo không chính xác áp suất nứt vỉa có thể gây ra các vấn đề nghiêm trọng như: mất tuần hoàn dung dịch khoan hoặc xảy ra hiện tượng "kick" dẫn đến phun trào…  

Bài báo giới thiệu các ứng dụng của trí tuệ nhân tạo trong lĩnh vực dầu khí, sử dụng phương pháp sử dụng ANN dựa trên các dữ liệu đầu vào gồm: độ sâu, hệ số Poisson, ứng suất địa tĩnh, áp suất lỗ rỗng  và dữ liệu đầu ra là áp suất nứt vỉa để xây dựng mô hình dự báo áp suất nứt vỉa cho giếng khoan thuộc bể Nam Côn Sơn. Nhóm tác giả đã so sánh với kết quả dự báo bằng phương pháp truyền thống cho thấy phương pháp sử dụng ANN cho kết quả dự báo áp suất nứt vỉa sát với kết quả đo thực tế nhất.
