Drilling parameter determination method, device and computer equipment

Abstract

The present specification provides a method, device and computer equipment for determining drilling parameters. Based on the method, a target function group including at least a maximum mechanical rotation speed function and a minimum mechanical specific energy function about the drilling process of a target well is constructed according to the drilling data of the target well. Then, a plurality of operation nodes are determined and called to jointly solve the target function group based on a preset fusion solving rule to obtain target result data meeting the requirements, wherein the preset fusion solving rule at least includes an improved dynamic neighborhood search sub-rule and an improved dynamic cooling sub-rule. Finally, the target drilling parameters matched with the target well are determined according to the target result data. Thus, the drilling construction scene can be better adapted, the solution space capability and solving accuracy during the optimization of drilling parameters can be effectively improved, the local optimal solution can be avoided, the target drilling parameters with better effect can be efficiently and accurately determined to guide the drilling construction of the target well.
