Description
Technical Field
The invention relates to the field of high-pressure manifolds, in particular to a high-pressure manifold with a fracturing prying fluid end.
Background
The connection between the hydraulic end fracturing fluid discharge port of the fracturing sledge and the high-pressure manifold confluence main pipe has two main types in the current connection mode: 1. a plurality of movable elbows and a plurality of straight pipes are combined; 2. the combination of a plurality of fixed right-angle elbows and a plurality of straight pipes provided with loop (rotating) flanges.
The two connection modes have the advantages that the positions of the fracturing fluid discharge port at the hydraulic end of the fracturing sledge and the connecting port of the high-pressure manifold converging main pipe can be adapted through a plurality of connected movable parts, and the position compensation effect is achieved.
The defects and shortcomings of the prior art are as follows:
both of the above-described connection methods involve a large number of connection points and complicated connection lines.
The following problems still exist when the connection mode of combining a plurality of movable elbows and a plurality of straight pipes is adopted: 1. the rubber part exists in the sealing position of the movable elbow movable joint, and due to the fact that the pressure of fracturing construction is high, the sealing part is prone to failure in the fracturing construction process, the pipeline is prone to leakage, and therefore the whole fracturing construction is prone to pause. 2. Based on the self characteristics of the movable elbow, the pipe diameter of the movable elbow cannot be too large (the maximum diameter of the movable elbow with the pressure level of more than 103.5MPa is only 3 inches), under the condition that the large diameter is needed, 2 groups of the plurality of movable elbows and a plurality of straight pipes can be connected between a fracturing fluid outlet at a hydraulic end and a high-pressure manifold confluence main pipe, the workload of on-site pipeline connection is multiplied, and the frequency of problems of the movable elbows is increased due to the increase of the movable elbows, so that the interruption frequency of fracturing construction is obviously increased. 3. The greater the number of movable bends, the greater the flow resistance in the pipeline and the greater the pressure loss.
The following problems also exist when a connection mode combining a plurality of fixed elbows and a plurality of straight pipes provided with loop (rotating) flanges is adopted: 1. each group of connecting manifolds needs 5 fixed elbows and 6 straight pipes provided with loop (rotating) flanges at least, and the number of pipelines is large. 2. In order to adapt to the position of a connecting port of a fracturing fluid outlet at a hydraulic end of a fracturing sledge and a high-pressure manifold converging main pipe, the pipeline arrangement is complex, and the existing installation is inconvenient.
