SYSTEM AND METHOD OF INJECTING A PROPPANT MIXTURE DURING FRACTURING

摘要

A method of forming an elevated pressure proppant-containing fracturing fluid for direct injection into a wellbore that reduces exposure of a substantial amount of the pumping equipment to the abrasive effects of proppant, as compared to conventional pumping equipment. The method includes providing a high pressure fluid stream to a nozzle having an inlet and an exit; accelerating the high pressure fluid stream through the nozzle from the inlet to the exit to increase the velocity thereof; providing a low pressure stream comprising a proppant to a suction chamber, the suction chamber positioned adjacent the nozzle exit; and mixing the low pressure fluid stream comprising a proppant with the high pressure fluid stream to form an elevated pressure proppant-containing fracturing fluid. A method for fracturing and a system for forming an elevated pressure proppant-containing fracturing fluid for injection into a wellbore are also provided.
