AI Technical Summary
Technical Problem
In existing technologies, PDC drill bits have a short service life in extremely hard or soft formations and are prone to impact failure in heterogeneous formations, resulting in drill bit damage, low drilling efficiency, and high costs.
Method used
By establishing a mapping model between formation data and the arrangement of diamond blocks, the PDC tooth with optimal overall performance is obtained. Deep learning methods are then used to optimize the performance adjustment of the PDC tooth and automatically adjust the arrangement of diamond blocks.
Benefits of technology
It improves the service life and drilling efficiency of PDC teeth in complex formations, reduces production costs and R&D cycle, and achieves efficient and accurate performance adjustment.

Abstract
A PDC cutter and a performance adjustment method and system therefor, and a computer-readable storage medium. The performance adjustment method comprises the following steps: acquiring training data, wherein the training data comprises formation data, failure modes of a PDC cutter, and arrangement and combination modes of blocks on a diamond layer; on the basis of the training data, constructing a mapping relationship model for input parameters and output parameters, wherein the input parameters comprise the formation data, and the output parameters comprise the arrangement and combination modes of the blocks on the diamond layer; training and optimizing the mapping relationship model; and on the basis of the mapping relationship model, acquiring the arrangement and combination mode of the blocks on the diamond layer that achieves the optimal comprehensive performance of the PDC cutter. The PDC cutter performance adjustment method and system and the computer-readable storage medium provide a more accurate, convenient and efficient solution for the performance adjustment of a PDC cutter.
