| 发明名称 | Casing filling tool | ||
| 摘要 | A system includes a tubular filling tool. In certain embodiments, the tubular filling tool includes a conductor pipe configured to receive a filling fluid flow from a top drive and a diffuser block communicatively coupled to the conductor pipe and configured to receive the filling fluid flow from the conductor pipe, wherein the diffuser block includes a plurality of fluid passages extending to external passages formed in an outer diameter of the diffuser block and configured to facilitate passage of the filling fluid flow to the external passages from within the diffuser block, wherein the external passages are configured to generate a swirl flow pattern in the filling fluid flow during a tubular filling process. | ||

| 主权项 | 1. A tubular filling tool, comprising: a conductor pipe configured to receive a filling fluid flow from a top drive; and a diffuser block communicatively coupled to the conductor pipe and configured to receive the filling fluid flow from the conductor pipe, wherein the diffuser block comprises a plurality of fluid passages extending to external passages formed in an outer diameter of the diffuser block and configured to facilitate passage of the filling fluid flow to the external passages from within the diffuser block, wherein the external passages are configured to generate a swirl flow pattern in the filling fluid flow during a tubular filling process, and each of the external passages comprises a helical shape extending about the outer diameter of the diffuser block, at least one of the external passages extending to a lower end of the diffuser block. | ||
