发明名称 Method of estimating well productivity along a section of a wellbore
摘要 Disclosed is a system and a method of estimating a well inflow profile along a section of a wellbore of a well passing through a formation. The method comprises: collecting field data as a function of time during testing of the well, analysing the collected field data to obtain selected field parameters, providing a created dynamic simulation model of the well inflow profile of the well based on at least the geometry of the well, defining a number of different possible inflow profile scenarios, simulating the defined inflow profile scenarios by means of the dynamic simulation model, analysing the simulated inflow profile scenarios to obtain characteristics of intermittent or slug flow behaviour in the form of selected modelling parameters as a function of time, comparing the selected modelling parameters as a function of time for each inflow profile scenario to the corresponding selected field parameters as a function of time and identifying the most likely inflow profile scenario on the basis thereof, and estimating the well inflow profile along the section of the wellbore based on the comparison of the selected modelling parameters as a function of time to the corresponding selected field parameters as a function of time.
