Zusammenfassung: | A system for lubricating multiple frac valves while allowing the operator to remain out of the red zone. A system of high flow mandrels and valves allows an operator to enter the red zone a minimal number of times. Generally, when using the system, the operator will enter the red zone prior to the fracking operation beginning to connect the various lines to each frac valve and then after the frac job is complete to disconnect the various lines from each frac valve. A high-pressure pump provides lubricant at a sufficient pressure and volume to a high-pressure manifold or high-pressure manifolds. The high-pressure manifolds supply the hose reels through valves located near the manifold. The hose reels in turn are the lines that are connected to each frac valve Using the system, the operator may remain outside of the red zone with the lubricant reservoir, the pump, the high-pressure manifolds, and the hose reels. When a well pad is shut down the operator chooses which frac valve to grease and commands the associated valve on the high-pressure manifold to open. The high-pressure pump is then actuated using the lubricant from the lubricant reservoir the pump increases the lubricant pressure to about 15,000 psi supplying it to at least a first high-pressure manifold. The high-pressure manifold then distributes the lubricant through the open valve to the desired hose reel and then to the frac valve which is inside the red zone. The operator repeats the process until each of the frac valves on the well pad are greased. The various fittings, lines, valves, and manifolds are chosen or manufactured to minimize pressure losses through the system between the high-pressure pump and the frac valve. |
