Manifold

The utility model provides a manifold. The manifold is used for fracturing oil layers, so that a steam injection well can be communicated with a production well. The manifold comprises a main passage, a first branch pipeline, a second branch pipeline and at least one liquid injection pump. The main passage is provided with liquid injection communication points, a first communication point and a second communication point, the first communication point and the second communication point respectively correspond to the steam injection well and the production well, and the liquid injection communication points are arranged between the first communication point and the second communication point; a first end of the first branch pipeline is communicated with the first communication point, and a second end of the first branch pipeline is connected with a first pipe in the steam injection well; a first end of the second branch pipeline is communicated with the second communication point, and a second end of the second branch pipeline is connected with a second pipe in the production well; liquid injection openings of the liquid injection pumps are communicated with the liquid injection communication points. According to the technical scheme, the manifold has the advantages that the working time spent on communicating oil layers via steam in the prior art can be greatly shortened, and a large quantity of steam can be saved.
