Корреляция горизонта и разлома по сейсмическому кубу. Построение карты с учётом разлома.

Summary

The video tutorial, led by Anton Kirillov, focuses on structural interpretation of narrow data, specifically horizon tracking and fault modeling in geological analysis. It covers automatic and semi-automatic tools for interpreting seismic horizons and building grids based on interpreted data. Kirillov demonstrates how to identify and process faults, and then integrate them into a 3D grid for accurate geological modeling. The tutorial emphasizes the importance of input geometry and offers tips on speeding up the interpretation process using hotkeys. Viewers are encouraged to ask questions and provide feedback for future tutorials.

Takeaways

• 📊 The speaker discusses the structural interpretation of narrow data, specifically focusing on chemical horizons and fault tracking.
• 🛠️ Tools like 'study of the tracking' are utilized to automatically or semi-automatically track phases in 3D space, which accelerates the interpretation process.
• 🌐 The horizon tracking is demonstrated using inline 624, and shortcuts like 'page up' and 'page down' are recommended for faster movement across the cube.
• 🔧 Automatic tools can be applied for horizon tracking, but if there are challenges, a switch to semi-automatic or manual modes is advised.
• 📈 A grid is created based on the interpreted horizon using specific geometric parameters, with recommendations to ensure the grid's geometry matches the cube data.
• 🖱️ Users can select parameters like grid cell size (e.g., 100m x 100m) and algorithms for surface construction, such as 'convergent gridding.'
• 🌍 Faults are incorporated into the grid to ensure proper geological modeling. The speaker demonstrates how to track and add faults for accurate results.
• 🔄 After interpretation, grids can be adjusted based on boundary constraints and further refined to meet expectations, particularly regarding fault placement.
• 🧪 Challenges in southern areas of the cube may require manual interpretation when automatic tools are insufficient.
• 📚 The speaker references additional resources available on a portal or book to explain concepts like geometry selection and algorithm choices in more detail.
