Based on such a configuration, the connection between the fracturing valve 20 and the first four-way connector assembly 32 can be achieved through the quick connector 31, and the disassembly and assembly are facilitated, which is beneficial to improve the maintenance efficiency. In addition, the fracturing fluid in the fracturing valve 20 can be delivered to the connection manifold 02 through the first four-way connector assembly 32, so as to be delivered downstream through the connection manifold 02.
[0056] It should be noted that the specific structure and connection principle of the quick connector 31 can refer to the prior art, and will not be described in detail here.
[0057] Based on the fracturing shunt manifold skid 01 described above, the embodiments of the present application further disclose a wellhead connection manifold 02 device, as shown in Figure 2 The disclosed wellhead connection manifold 02 device includes a connection manifold 02, a wellhead tree 03, and the fracturing shunt manifold skid 01 described above, wherein the connection manifold 02 is connected between the fracturing shunt manifold skid 01 and the wellhead tree 03, so as to deliver the fracturing fluid delivered by the fracturing shunt manifold skid 01 to the wellhead tree 03 through the connection manifold 02, and the wellhead tree 03 delivers the fracturing fluid to the underground, so as to facilitate the fracturing operation.

Based on such a configuration, the installation stability between the fracturing pipe 021 and the second connector assembly 30 can be achieved through the clamp 022, so as to prevent the fracturing fluid from leaking. In addition, the fracturing pipe 021 can deliver the fracturing fluid to the wellhead tree 03.

[0060] Continuing to refer to Figure 2 In some embodiments, the wellhead tree 03 can include a hydraulic connector 031, a second four-way connector assembly 032, and a plurality of wellhead tree valves 033, wherein the plurality of wellhead tree valves 033 are sequentially connected in the vertical direction, the hydraulic connector 031 is connected with the wellhead tree valve 033 located at the top of the plurality of wellhead valves, the second four-way connector assembly 032 is connected between the plurality of wellhead tree valves 033, and the connection manifold 02 is connected with the second four-way valve.
[0061] Based on the above setting, the fracturing fluid delivered through the connection manifold 02 flows into the second four-way valve, and under the action of the hydraulic connector 031, the fracturing fluid is delivered from the second four-way valve to the wellhead tree valve 033, and is delivered downstream by the wellhead tree valve 033, and finally delivered to the underground to realize fracturing operation.
[0062] It should be noted here that the specific structure of the hydraulic connector 031 and its working principle can be referred to the prior art, which will not be described in detail here.

Moreover, the flexible pipe has less bending, which is conducive to reducing the scouring effect of the fracturing fluid and reducing vibration.
[0065] Of course, during the high-power fracturing operation, the flexible pipe can cause vibration, in which case the flange straight pipe can be used to deliver the fracturing fluid.
[0066] As described above, the fracturing shunt manifold skid 01 and the wellhead tree 03 in the embodiment of the present application can be connected through the flange four-way valve (i.e., the first four-way assembly 32 described above) and the flange straight pipe (i.e., the connection manifold 02 described above), without the need for a single pipe universal device, which is conducive to reducing the use of the manifold and reducing equipment costs.
[0067] The fracturing shunt manifold skid 01 and the flexible pipe can be directly connected using the hydraulic connector 031, which can reduce the installation of the field manifold and improve installation convenience; and the flexible pipe has less bending, which is conducive to reducing the scouring of the fracturing fluid on the flexible pipe and thus reducing vibration.
[0068] The embodiments of the present application are described above in combination with the drawings, but the present application is not limited to the above specific embodiments, and the above specific embodiments are only illustrative and not limiting, and those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope protected by the claims.
