Quantitative Analysis of the Stability of a Mud-Return Circulation System in a Riserless Mud-Recovery Drilling System

Riserless mud-recovery (RMR) drilling technology was widely applied in recent years. Compared with traditional deepwater drilling, RMR can improve efficiency, reduce risks, and minimize environmental effects. This paper focuses primarily on the stability of a mud-return circulation system an system. First, various factors that affect are analyzed. An analytical model for skid-and-mud-return line is established. Second, relevant data derived from theoretical calculations experiments. ABAQUS software used to analyze effects each factor The influencing patterns summarized. Furthermore, under different operating conditions analyzed based coupling multiple factors. support vector regression derivative significance weight analysis (SVR-DWSA) algorithm employed perform effect system’s stability. Finally, research findings system, conclusions recommendations drawn. results this study provide valuable references application technology.
