摘要： A wellbore plug container includes a body with an interior to house a lower plug and an upper plug; a manifold system in fluid communication with the interior of the body; a first valve assembly to direct fluid flow into the interior of the body; and a second valve assembly to direct fluid flow into the interior of the body; a tubular connection to connect the body and manifold system to a casing for use with a wellbore; fluid flow is first directed below the lower plunger via the manifold system; the lower plunger assembly is retracted in a second step and fluid flow is directed to below the upper plunger assembly and above the lower plug, thereby causing the lower plug to launch; and fluid flow is diverted to above the upper plug after retraction of the upper plunger assembly in a third step to launch the upper plug.

摘要： 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.

摘要： A fluid diverter system for use in well drilling operations, the fluid diverter system includes one or more plug chambers mounted within a pipe, and a first valve positioned adjacent to one of the one or more plug chambers, the first valve rotationally mounted within the pipe to selectively rotate between an open position and a closed position, the open position allows fluid flow through a main bore as created by the one or more plug chambers while blocking fluid flow around a perimeter of the one or more plug chambers; and the closed position allows fluid flow around the perimeter of the one or more plug chambers while blocking fluid flow through the main bore; the first valve is machined and manufactured as a single unit.
