The mass flow rate cannot be constant

Please login with a confirmed email address before reporting spam

A constant flow rate is specified by setting the well, but the Darcy mass flow is not constant in the derived value selected to calculate the well.The initial flow rate was 10.995kg/s, and at day 700, the flow rate changed surprisingly to 143.67kg/s.Why does the flow rate change and how to inject a constant flow rate?(pictures are attached at the end of the article) Thank you for your generous answer.
