Abstract

The disclosure provides an adjustable modular skid system with a plurality of skid modules to support oil field fluid components, such as manifolds, mixing blocks, collection blocks, fracturing pumps, piping and connections, and other devices used to transport water, sand slurries, gas, oil, or other fluids in oil field applications. The skid system has vibration adjusting features. The skid modules can be coupled together through piping and relevant connections at the well site. If appropriate, the skid modules can be supported on pilings or other foundational supports. The system can be assembled remotely, started and tested, partially disassembled into the skid modules, and then installed at the well site with minimal additional effort by generally providing lines and connections between the modules. Excessive vibrations in the system can be reduced by adjusting an overall stiffness of the system to change a natural frequency of the system.

Claims

1. An oil field fluid transportation system, comprising:

a first skid module having a support frame;

a first portion of a first manifold coupled to the frame;

a fluid fitting fluidicly coupled to the first portion of the first manifold; and

an adjustable coupler that couples the fluid fitting, the first portion of the first manifold, or a combination thereof to the frame, the adjustable coupler being adjustable for an amount of compression, tension, or both on the fluid fitting, the first portion of the first manifold, or a combination thereof coupled to the frame to change a natural frequency of at least a portion of the system.

2. The system of claim 1, wherein the adjustable coupler comprises a threaded coupler disposed between the frame and a hold down member with the fluid fitting, first portion of the first manifold, or a combination thereof disposed between the frame and the hold down member.

3. The system of claim 1, further comprising a pump fluidicly coupled to the first manifold, the pump having vibrations during operation, and the adjustable coupler being configured to change a frequency of response of the system to the pump vibrations.

4. The system of claim 1, further comprising:

a second skid module having a support frame;

a second portion of the first manifold coupled to the frame of the second skid module; and

a connection line fluidicly coupled between the first portion and the second portion of the first manifold.

5. The system of claim 1, further comprising:

a second skid module having a frame;

a first portion of a second manifold coupled to the frame of the second skid module;

a second portion of the second manifold coupled to the frame of the first skid module;

a connection line fluidicly coupled between the first portion and the second portion of the second manifold.

6. A method of supporting an oil field fluid transportation system, comprising:

obtaining a first skid module having a support frame;

coupling a first portion of a first manifold to the frame;

to coupling a fluid fitting fluidicly to the first portion of the first manifold; and

changing a natural frequency of at least a portion of the system by adjusting an amount of compression, tension, or both on the coupling of the fluid fitting, the first portion of the first manifold, or a combination thereof to the frame.

7. The method of claim 6, further comprising pumping fluids through the first manifold thereby creating vibrations to the system and wherein changing the natural frequency of at least the portion of the system comprises reducing a magnitude of the vibrations.

8. The method of claim 6, further comprising fluidicly coupling a second portion of the first manifold on a second skid module with the first portion of the first manifold.

9. The method of claim 8, further comprising changing a natural frequency of at least a portion of the system by adjusting an amount of compression, tension, or both on the coupling of the second portion of the first manifold.
