Title:
PERFORATION DETONATION ANALYSIS METHOD AND APPARATUS FOR TEST AND COMPLETION STRING
Document Type and Number:
WIPO Patent Application WO/2023/124938
Kind Code:
A1
Abstract:
Disclosed is a perforation detonation analysis method for a test and completion string. The method comprises: creating and executing a detonation analysis task by means of a combined model of a three-dimensional test and completion string finite element model and a rockshaft finite element model, and analyzing a task result to obtain detonation engineering data of a test and completion string. The method can improve the accuracy and the analysis efficiency of the perforation detonation analysis of the test and completion string, thereby reducing the analysis cost.
