Autonomous annular pressure control assembly for perforation event
摘要:
A system and method of controlling a dynamic time-pressure profile associated with a perforation event that includes extending a perforation assembly within a casing string; firing a perforation gun of the perforation assembly; measuring, using a sensor of the perforation assembly, pressure within the casing string, wherein the measured pressure forms the dynamic time-pressure profile; identifying a first measured pressure within the dynamic time-pressure profile; identifying, using a controller of the perforation assembly, a first difference between the first measured pressure and a first reference pressure; and adjusting, using a first pressure generator of the perforation assembly, the pressure in response to the first difference to control the dynamic time-pressure profile; wherein the sensor, the controller, and the first pressure generator provide a feedback control loop.
