COUPLING LOW-PRESSURE MANIFOLD PASSAGES IN HYDRAULIC FRACTURING SYSTEMS

原文（中文）

A method for performing a hydraulic fracturing operation includes providing a manifold assembly. The manifold assembly has a low-pressure section with a first passage that receives a clean fluid and a second passage that receives a slurry. Each passage includes outlets to provide the clean fluid and the slurry to pumps. An outlet end of the first passage is coupled to an outlet end of the second passage via a flexible fluid coupler. A first valve is between outlets of the first passage, and a second valve is between outlets of the second passage. The manifold assembly has a high-pressure section with a third passage that receives the clean fluid and the slurry from the pumps. Further, the method includes controlling, based on an open or closed position of the first and second valves, whether each outlet, of the first and second passages, is provided with clean fluid or slurry.
