Technical Field

The application belongs to the technical field of manifold structural design, and particularly relates to a manifold sledge and fracturing equipment.

Background

The manifold sleds have the functions of collecting and redistributing the fluid and are widely applied to operations such as fracturing, and taking fracturing operation as an example, the manifold sleds can collect low-pressure fracturing fluid output by the sand mulling trucks and distribute the collected low-pressure fracturing fluid to a plurality of fracturing pump trucks, and can collect and convey the high-pressure fracturing fluid pressurized by the fracturing pump trucks to well heads.

Along with the improvement of construction displacement, pressure and continuous operation time, the performance of the manifold sledge needs to be improved along with the improvement, and therefore the sizes of all parts of the manifold sledge can be increased. However, due to the limitation of traffic transportation regulations, the overall size of the manifold skid cannot be too large, so that an irreconcilable contradiction occurs between the performance of the manifold skid and the transportation requirement, and great challenges are brought to the structural design of the manifold skid.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or described herein. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The manifold skid and the fracturing equipment provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by specific embodiments and application scenarios thereof.

Referring to fig. 1 and 2, an embodiment of the present application discloses a manifold skid, which includes a skid body 100, a manifold assembly 200, and a control assembly 300. The skid body 100 may serve as a base member for the manifold skid, which may provide a mounting base for other components. The manifold assembly 200 and the control assembly 300 are both disposed on the skid body 100, and the control assembly 300 is mounted on a side of the manifold assembly 200 away from the skid body 100 through the supporting device 400, and a height of the control assembly 300 is greater than a height of the manifold assembly 200. In other words, the skid 100, the manifold assembly 200, and the control assembly 300 may be arranged in sequence along the height direction. It should be noted that the height direction here may be a vertical direction when the manifold skid is working.

The supporting device 400 may be a block structure or a frame structure, and the supporting device 400 may be connected to the manifold assembly 200 and the control assembly 300 by fasteners such as bolts, so as to connect the control assembly 300 and the manifold assembly 200. Because the control assembly 300 can be installed on the basis of the manifold assembly 200, the supporting device 400 only needs to be arranged corresponding to the space between the control assembly 300 and the manifold assembly 200, and the size of the supporting device is small, so that excessive space does not need to be reserved for arranging the supporting device 400, more space of the manifold skid can be used for arranging other components, and the structural compactness of the manifold skid is further improved.

The embodiment of the application can make full use of the upper space of the manifold assembly 200 to install the control assembly 300, and the arrangement mode makes the structure of the manifold sledge more compact, so that even if the size of each part of the manifold sledge is larger, the whole size of the manifold sledge is not overlarge, and the transportation requirement is met. Therefore, the scheme can meet the transportation requirement and allow the sizes of all parts of the manifold skid to be properly increased so as to improve the performance of the manifold skid. In addition, the present embodiment may modularly design the skid body 100, the manifold assembly 200 and the control assembly 300, so that the manifold skid may be more compact and simpler in structural design, and the independence between the components may be increased to facilitate maintenance of the manifold skid. Because the control assembly 300 is higher, when an operator stands on the sledge body 100, the height difference between the operator and the control assembly 300 is more reasonable, and the operation of the operator is more convenient.

The manifold assembly 200 is mainly used for flowing fluid, and the manifold assembly 200 may only flow high-pressure fluid, only flow low-pressure fluid, or both high-pressure fluid and low-pressure fluid. Optionally, manifold assembly 200 includes a low pressure manifold assembly 210 and a high pressure manifold assembly 220, low pressure manifold assembly 210 being configured to flow low pressure fluid and high pressure manifold assembly 220 being configured to flow high pressure fluid. The high pressure manifold assembly 220 is located between the low pressure manifold assembly 210 and the control assembly 300, that is, the skid body 100, the low pressure manifold assembly 210, the high pressure manifold assembly 220, and the control assembly 300 may be arranged in sequence along the height direction. This arrangement allows the skid body 100, the low pressure manifold assembly 210, the high pressure manifold assembly 220, and the control assembly 300 to be more compactly distributed in the height direction, thereby allowing the overall size of the manifold skid to be smaller and facilitating modular design of the manifold skid.

Alternatively, low pressure manifold assembly 210 may be coupled to skid 100 via U-bolts or the like, and low pressure manifold assembly 210 may include pipes for fluid flow, which may be straight pipes or curved pipes. Alternatively, high pressure manifold assembly 220 may be mounted directly to skid 100 via brackets, or may be coupled to skid 100 via low pressure manifold assembly 210. The high pressure manifold assembly 220 may include pipes for fluid flow, which may be straight pipes or curved pipes.

The manifold assembly 200 may include a valve 222, and the valve 222 may control the flow state of the fluid. When the manifold assembly 200 includes a low pressure manifold assembly 210 and a high pressure manifold assembly 220, the low pressure manifold assembly 210 and the high pressure manifold assembly 220 may include at least one valve 222. Optionally, the high pressure manifold assembly 220 includes a communication connector 221 and a valve 222, the valve 222 being disposed in the communication connector 221. The communication joint 221 may be provided with a plurality of ports for allowing the communication joint 221 to communicate with other components. The valve 222 can control the state of the connection joint 221, thereby achieving the functions of controlling the flow direction of the fluid and the like. The number of the communication joints 221 may be one, but in order to control the flow direction of the fluid in a wider range, the number of the communication joints 221 may be at least two, and the high pressure manifold assembly 220 further includes a communication pipe 223 through which the adjacent communication joints 221 communicate. The communication pipe 223 is used for fluid flow, and the communication pipe 223 may be a straight pipe or an elbow pipe.

In an alternative embodiment, the control assembly 300 may include a housing 310, a control system and a pipeline, the housing 310 is provided with a threaded hole, the control system is disposed in the housing 310, one end of the pipeline is connected to the control system, the other end of the pipeline passes through the threaded hole and is connected to the manifold assembly 200, and optionally, the pipeline may be connected to a control portion of the valve 222 of the manifold assembly 200. The control system can comprise a hydraulic system and an electric control system, wherein the hydraulic system can comprise a motor, various hydraulic elements, a hydraulic oil tank and the like, correspondingly, the pipeline can comprise a hydraulic pipeline which can be connected with each part of the hydraulic system; the electronic control system can comprise various control components, control cabinets and the like, and correspondingly, the pipelines can comprise electronic control pipelines which can be connected with the various parts of the electronic control system. It can be seen that the control system inside the housing 310 can be connected to the components outside the housing 310 through pipelines, thereby implementing the control function of the control system. Optionally, the pipeline and the control system may be connected by a quick-connect interface such as a union interface, thereby improving the efficiency of disassembling and assembling the control assembly 300.

Only one box 310 of the control assembly 300 can be provided, because the control system includes more components, at least two boxes 310 can be provided, and the at least two boxes 310 can respectively accommodate different parts of the control system, so that the boxes 310 can cover the components which are intensively arranged, and at this time, the matching degree of the size of the box 310 and the overall size of the components which need to be accommodated is higher, which is beneficial to reducing the size of the box 310, and is also more convenient for the modular design of the control assembly 300.

The housing 310 may house the control system to protect the control system and facilitate modular design of the control assembly 300. In addition, at least one part of the pipeline is positioned in the box body 310, so that the exposed part of the pipeline is less, the risks of aging, collision of the pipeline with other parts and the like caused by long-time exposure of the pipeline are reduced, and the service life of the pipeline is longer; meanwhile, after the exposed part of the pipeline is reduced, the disorder degree of the pipeline can be reduced, so that the manifold sledge is more attractive integrally.

The threading holes formed in the box body 310 can allow one end of a pipeline to pass through, the number of the threading holes can be one, and all the pipelines can pass through the box body 310 through the threading holes. When the manifold assembly 200 includes at least two valves 222, the threading holes are likely to be closer to one part of the valves 222, farther from the other part of the valves 222, or even farther from all the valves 222, and the farther the threading holes are from the valves 222, the more the parts of the pipeline between the threading holes and the valves 222 are, i.e. the more the exposed parts of the pipeline are, thereby limiting the protection of the pipeline by the box 310. To this end, the control assembly 300 may be provided with at least two threading holes, each corresponding to at least one valve 222. When the number of the box bodies 310 of the control assembly 300 is one, all the threading holes are opened in the box body 310; when the number of the box bodies 310 of the control assembly 300 is at least two, each box body 310 may be provided with at least one threading hole, so that the pipeline in each box body 310 can pass through the threading hole. After the arrangement, the position of the threading hole can be determined according to the position of each valve 222, so that the distance between the threading hole and the corresponding valve 222 is shortened as much as possible, and the exposed part of the pipeline is reduced.

When the manifold assembly 200 includes the high pressure manifold assembly 220, the control assembly 300 may be coupled to the communication connector 221 via the support apparatus 400. In other words, the supporting device 400 can be mounted on the communication joint 221, and the communication joint 221 has higher structural strength, so that the control assembly 300 can be mounted on the communication joint 221 more reliably, and the high-pressure manifold assembly 220 is not easily bent or damaged due to the larger weight of the control assembly 300. Alternatively, the communication connector 221 may include a first connector 221a, the first connector 221a may be a four-way connector, and the control assembly 300 may be connected to the first connector 221a through the supporting device 400.

Alternatively, a single casing 310 may be connected to only one communication joint 221, and in order to stably mount the control assembly 300 to the communication joint 221, the middle of the casing 310 may be connected to the communication joint 221. However, with this structure, the two ends of the box 310 are suspended, and once the control assembly 300 is subjected to an external force or the center of gravity of the control assembly 300 changes, the control assembly 300 is easily tilted or even separated from the connection joint 221. In order to prevent this, the two ends of the casing 310 may be connected to different communication joints 221, so as to avoid the two ends of the casing 310 from being suspended, and thus the control assembly 300 may be more stably mounted on the manifold assembly 200.

When the two ends of the box 310 are connected to different communication joints 221, respectively, it means that the two ends of the box 310 are closer to the corresponding valves 222 on the communication joints 221, in order to reduce the exposed parts of the pipelines, threading holes may be provided at the two ends of the box 310, so that a part of the pipelines are connected to the corresponding valves 222 or other parts near the valves 222 through the threading holes at one end of the box 310, and another part of the pipelines are connected to the corresponding valves 222 or other parts near the valves 222 through the threading holes at the other end of the box 310.

Further, the manifold skid further comprises a safety pressure relief assembly 500, the safety pressure relief assembly 500 can set an upper limit value of the working pressure, and when the working pressure is greater than the upper limit value, the pressure can be relieved as soon as possible through the safety pressure relief assembly 500, so that the safety of the equipment during operation is ensured. The safety pressure relief assembly 500 may be mounted on a side of the manifold assembly 200 facing away from the skid body 100 by a fastener such as a bolt, and optionally, the communication joint 221 of the high-pressure manifold assembly 220 may include a second joint 221b, and the safety pressure relief assembly 500 may be disposed on the second joint 221b, and the second joint 221b may be a five-way joint. The height of the safety pressure relief assembly 500 is greater than that of the manifold assembly 200, the control assembly 300 and the safety pressure relief assembly 500 are respectively located at two ends of the manifold assembly 200, a reserved space 101 is formed between the safety pressure relief assembly 500 and the control assembly 300, the reserved space 101 can be used for storing parts such as vulnerable accessories and tools of a manifold skid, the reserved space 101 can realize centralized storage of the parts, and further the parts are prevented from being lost due to disorder.

When the manifold sleds are operated, there are large vibrations, which when applied to the control assembly 300, are liable to cause failure of the connection between the control assembly 300 and the manifold assembly 200 and damage to the components contained in the control assembly 300. Based on this, optionally, the manifold sledge further comprises a vibration damping device 600, and the control assembly 300 is connected with the supporting device 400 through the vibration damping device 600. The vibration damping device 600 herein can prevent vibration from being transmitted from the manifold assembly 200 to the control assembly 300, thereby preventing the control assembly 300 from being separated from the manifold assembly 200, and also preventing damage to components included in the control assembly 300 due to vibration. Alternatively, the vibration damping device 600 may include a spring or other component having a damping effect, which is not limited by the embodiment of the present application.

The embodiment of the application also discloses fracturing equipment, which comprises the manifold sledge in any embodiment.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the present embodiments are not limited to those precise embodiments, which are intended to be illustrative rather than restrictive, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope of the appended claims.
