AI Technical Summary
Existing shale gas horizontal well trajectory design methods fail to comprehensively consider the geological characteristics of oil and gas reservoirs, resulting in wasted and ineffective wellbore design, and are particularly unsuitable for shale oil and gas wells.
The wellbore trajectory design method based on single-well production, efficiency and reservoir geological characteristics selects high-quality production areas by obtaining information on predicted sweet spots and fracturing range, determines the wellbore target location and designs the wellbore trajectory, and optimizes the trajectory design to reduce waste by considering engineering difficulty and risk.
It effectively reduces wellbore waste, improves energy utilization efficiency, lowers operating costs, and increases operating efficiency, and is suitable for various oil and gas field types.
