Patent ID: 8122949

Claim:
A fracturing system, for improving fluid dynamics of incoming fracturing fluid introduced to a wellbore and protecting a conveyance string passing therethrough from erosive effects of the incoming fracturing fluid, the system comprising: a fracturing head having a main bore extending therethrough, and having two or more side fluid ports spaced around the main bore, the main bore receiving the incoming fracturing fluid therein; and a wear resistant, tubular sleeve having a sleeve bore for receiving the conveyance string therethrough, a top portion fit to the main bore uphole of the two or more side fluid ports, and a downhole portion extending downwardly to below the two or more side fluid ports and forming an annular space between the downhole portion and the main bore, an annular cross-sectional area of the annular space increasing adjacent the two or more side fluid ports for decreasing a velocity of the incoming fracturing fluid, wherein the downhole portion intercepts the incoming fracturing fluid and redirects the fracturing fluid down the increased annular cross-sectional area and to the wellbore.
