Controlling oil well pressure during drilling is one of the most complex and hazardous processes in exploration stage. The system undergoes constant variations, influenced by factors such as depth, which turn affects other process parameters. Consequently, applying a time-invariant control strategy becomes impractical. This study aimed to identify PID parameters necessary regulate bottom-hole across different operating depths, with goal maintaining stability robustness. To achieve this, were tested using Gain Scheduling (GS) controller, adjusted gains according various points. In first section, development mathematical model process, based on fluid mechanics, presented. Linearizing this introduced an integrating element, complicated dynamics. second we present design controller Internal Model Control (IMC) tuning methodology address integration challenges. Finally, for depths obtained integrated into GS via Matlab Simulink. controller’s performance was then evaluated through simulations typical issues, simulated disturbances, confirming its viability. GS-controlled compared adaptive demonstrating superior former.

In the process of CO2 geological storage in salt water layer, leakage along wellbore will seriously affect effective target area. To solve this problem, based on investigation a large number failure cases and gas wells injection stage wellbore, influencing factors risk were investigated detail. Based analytic hierarchy (AHP) extension theory, 17 basic evaluation indexes selected from 6 perspectives to establish index system wellbore. The established was used evaluate well X field BZ Block. results showed that tubing had smallest weight, followed by cement sheath, casing–cement sheath interface sheath–formation largest accounting for 23.73% 34.32%, respectively. grade Ι, with minimal risk. effect excellent. comprehensively considers string, micro-annulus interface, which can provide scientific basis assessment under layer.
