Zusammenfassung:A combination of an autofill tube and an interchangeable ball cage for use in an autofill conversion assembly during well operations includes the tube extending to a downhole opening, the tube has a mounting mechanism to releasably mount the tube within an outer member; the interchangeable ball cage having a main body forming a bore; a downhole opening; circulation ports; and an attachment mechanism removably connecting the main body to the autofill tube; the downhole opening has a diameter selected to prevent a conversion ball from falling therethrough; the circulation ports provide fluid flow through the interchangeable ball cage such that the circulation ports have a number and size to create a preset maximum flowrate associated with the combination of the autofill tube and the interchangeable ball cage; and the interchangeable ball cage is to be selected based on the preset maximum flowrate desired at a well site.
