CARBONATE ROCK FRACTURE DRILLING TRAJECTORY DESIGN AND CONTROL METHODS

摘要

Carbonate rock fracture drilling trajectory design and control methods, comprising: utilizing earthquake data to obtain the contours of carbonate rock fractures; determining a safe distance from each carbonate rock fracture; determining a segment-based drilling trajectory for each carbonate rock fracture, and connecting the segment-based drilling trajectories of neighboring carbonate rock fractures to obtain a carbonate rock fracture drilling trajectory. The described design and control methods optimize the carbonate rock reservoir drilling trajectory, thus improving communication between a horizontal well and the fractures. This reduces development costs, increases exploration and development efficiency and, at the same time, eliminates leaks resulting from the drilling process, thereby allowing for smooth drilling to a target well depth.
