摘要:
The disclosure relates to a method for estimating a flow out of at least one fluid pump for injecting fluid in a well, comprising : - determining a calculation model for the flow rate of a pump exiting the at least one pump, said calculation model permitting the calculation of the flow rate in function of at least one calculation parameter ( p, SPM ) related to the at least one fluid pump ; then - providing at a plurality of measuring times (t m ), a set of measurement values ( p DH,m , p B,m , SPM DH,m , SPM B,m ) representative of said at least one calculation parameter ; then - estimating (86) the flow rate exiting the pump in function of the model and of said at least one calculation parameter.
