Description

Technical Field

[0001] The present invention relates to the technical field of oil extraction, and in particular to a fracturing manifold vehicle and an application method thereof. Background Art

[0002] During oil extraction operations, hydraulic fracturing is often used to disrupt the formation structure, thereby improving the flow environment of oil underground and increasing oil well production. Fracturing operations typically require several fracturing trucks to operate simultaneously. A fracturing manifold system is used to collect the fluid output from the fracturing trucks to increase the flow and pressure of the fracturing medium.

[0003] The existing invention patent application with application publication number CN118933696A provides a vehicle-mounted high-pressure fracturing manifold, which belongs to the technical field of vehicle-mounted high-pressure fracturing manifolds. The vehicle-mounted high-pressure fracturing manifold includes a support base, a vehicle-mounted fixing, an installation assembly, a manifold assembly, a docking assembly and a valve assembly. The vehicle-mounted fixing is provided at a position corresponding to the vehicle body and the support base. The vehicle-mounted fixing is used to fix the support base on the vehicle body and reduce the impact of the vehicle body shaking on the manifold assembly; the top of the vehicle-mounted fixing is fixed with the manifold assembly through the installation assembly, and the installation assembly is used to ensure the stability of the manifold assembly fixed on the top of the vehicle-mounted fixing; the manifold assembly includes a high-pressure main pipe, a shunt pipe and a discharge pipe, and the high-pressure main pipe is a cylindrical pipe structure.

[0004] As mentioned in the above technical solution, the vehicle-mounted high-pressure fracturing manifold mentioned therein fixes the manifold assembly to the vehicle body through a support base, which is a common structure of existing vehicle-mounted fracturing manifolds; the current vehicle-mounted fracturing manifolds are mostly carried on trailers. When used, the manifold assembly needs to be lowered by lifting equipment, placed on the ground, and then connected to the liquid outlet pipeline of the fracturing vehicle. This assembly process is relatively time-consuming and cannot be adjusted horizontally according to the ground; in particular, the pipelines in some manifold assemblies are driven by hydraulic cylinders to automatically connect to the fracturing vehicle. If the posture of the manifold assembly is unstable, the connection will be inconvenient, and even the manifold assembly will be unable to be connected to the fracturing vehicle.

[0074] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0075] like Figures 1 to 10 As shown, the fracturing manifold vehicle of the present invention includes a first carrier 1, a second carrier 2, a front wheel group 3, a rear wheel group 4, a manifold assembly 5, a power part 6, a hydraulic cylinder 7, a connecting part 8, a pipe rack assembly 9 and a lifting device 10.

[0076] like Figure 1 、 Figure 5 and Figure 6 As shown, the first carrier 1 and the second carrier 2 are arranged in parallel; the front wheel group 3 is rotatably arranged on the first carrier 1; the rear wheel group 4 is rotatably arranged on the second carrier 2, and two rear wheel groups 4 are arranged in parallel, and the rear wheel groups 4 are self-driving wheel groups; the manifold assembly 5 is hoisted at the bottom of the first carrier 1; the power member 6 is arranged on the second carrier 2, and the power member 6 is used to drive the first carrier 1 to swing up and down with the front wheel group 3 as the axis;

[0077] As shown in the above structure, the first carrier 1 and the second carrier 2 are split structures, which are connected by a power member 6; the first carrier 1 carries the manifold assembly 5. In this way, when in use, the power member 6 can drive the first carrier 1 and the manifold assembly 5 to swing up and down with the front wheel group 3 as the axis, thereby adjusting the posture of the manifold assembly 5, thereby facilitating the connection between the manifold assembly 5 and the fracturing truck, and facilitating the emptying of the manifold assembly 5;

[0078] Specifically, the front wheel group 3 and the rear wheel group 4 are connected to the first carrier 1 and the second carrier 2 through a suspension assembly composed of components such as leaf springs to form a basic frame structure;

[0079] The manifold assembly 5 is hoisted at the bottom of the first carrier 1, which makes the manifold assembly 5 lower as a whole, facilitating manual assembly work. That is, after the fracturing manifold vehicle is in place, the tractor head is detached, and the horizontal posture of the first carrier 1 and the manifold assembly 5 is adjusted by the power member 6. Then, the manifold assembly 5 can be connected to the liquid outlet pipeline of the fracturing vehicle without moving the manifold assembly 5 to the bottom surface, which improves the convenience of assembly;

[0080] Specifically, the rear wheel group 4 connected to the second carrier 2 is set as a self-driving wheel group or is provided with a walking drive mechanism. In this way, when the posture of the first carrier 1 is adjusted, the second carrier 2 can move synchronously toward the first carrier 1, thereby ensuring that the front wheel group 3 of the first carrier 1 remains stationary, thereby improving the stability of the adjustment; the rear wheel group 4 has an independent power source, for example, a motor is set on the second carrier 2, and then the rear wheel group 4 is driven to rotate through transmission components such as a transmission shaft.

[0081] In a specific application, the first carrier 1 is towed by a tractor head, and an independent brake component or a limit component is provided in the front wheel group 3 at the bottom of the first carrier 1, so that after the tractor head is separated from the first carrier 1, the front wheel group 3 does not move when the power member 6 adjusts the first carrier 1, thereby ensuring the stability of the position;

[0082] Among them, the brake component can adopt the existing mechanical handbrake, that is, a parking mechanism composed of components such as a pull rod, a ratchet, a steel cable and a brake shoe to lock the front wheel group 3, thereby achieving the limitation of the first carrier 1, so that when the first carrier 1 is pitched and adjusted, the position can be ensured not to change.

[0083] As Figure 9 and Figure 10 shown, the second carrier 2 includes a rear frame body 21, a first U-shaped frame 22 and a carrier 23, wherein the rear frame body 21 is rotationally connected with the rear wheel set 4, and the rear frame body 21 is open at one end towards the first carrier 1; the open end of the first U-shaped frame 22 is connected with the open end of the rear frame body 21; the carrier 23 is connected with the rear frame body 21, and the first U-shaped frame 22 and the carrier 23 both extend downward; the power member 6 is arranged on the carrier 23;

[0084] As the above structure, the rear frame body 21 of the second carrier 2 is open at one end, and is provided with the first U-shaped frame 22 for structural reinforcement, and is also provided with the carrier 23 for mounting the power member;

[0085] Among them, since the first U-shaped frame 22 and the carrier 23 both extend downward, i.e. extend towards the ground, this makes the carrier 23 located at the inner side of the whole second carrier 2 and arranged downward, so after carrying the power member 6, the space of the second carrier 2 is fully utilized;

[0086] Among them, the first U-shaped frame 22 is arranged, which connects the opening of the rear frame body 21, which improves the overall structural strength of the second carrier 2, and the downward extending structure of the first U-shaped frame 22 also facilitates the connection of the power member 6 and the first carrier 1;

[0087] Further, the upper parts of the first carrier 1 and the second carrier 2 can both carry other engineering equipment, which expands the carrying space of the carrier and improves the carrying capacity.

[0088] As Figure 2 and Figure 10 shown, the power member 6 includes a speed reducer 61, a motor 62, a worm 63, a worm gear 64, a rotating shaft 65 and a swing arm 66, wherein the speed reducer 61 is arranged on the carrier 23; the motor 62 is arranged on the carrier 23, and the main shaft of the motor 62 is connected with the input shaft of the speed reducer 61; the worm 63 is connected with the output shaft of the speed reducer 61; the worm gear 64 is arranged on the rotating shaft 65, the rotating shaft 65 is connected with the carrier 23 through a bearing seat, and the worm gear 64 is engaged with the worm 63; one end of the swing arm 66 is connected with the rotating shaft 65, and the other end is hingedly connected with the first carrier 1;

[0089] As the above structure, when the attitude of the first carrier 1 is adjusted, the power member 6 drives the speed reducer 61 to work by the motor 62, then drives the worm 63 and the worm gear 64 to rotate by the speed reducer 61, so as to drive the swing arm 66 to swing by the rotating shaft 65, since the swing arm 66 is hingedly connected with the first carrier 1, the first carrier 1 can realize the up-down pitching swing adjustment, so as to ensure the correct attitude of the manifold assembly 5;

[0090] During this adjustment, the front wheel group 3 under the first carrier 1 remains stationary relative to the ground. At this time, the rear wheel group 4 of the second carrier 2, through its driving structure, moves synchronously toward the first carrier 1 or away from the first carrier 1 during adjustment, thereby adapting to the change in the distance between the first carrier 1 and the second carrier 2 during adjustment, which is beneficial to reducing the load on the power component 6.

[0091] The above power member 6 can also be replaced by various driving members such as telescopic cylinders and connecting rods.

[0092] like Figure 4 、 Figure 7 and Figure 8 As shown, the first carrier 1 includes a front frame 11, an L-shaped frame 12, a second U-shaped frame 13 and a connecting rod 14, wherein one end of the front frame 11 is open and faces the first U-shaped frame 22; two L-shaped frames 12 are provided at the open end of the front frame 11; the second U-shaped frame 13 is connected to the two L-shaped frames 12; the connecting rod 14 is provided on the second U-shaped frame 13 and is hinged to the swing arm 66;

[0093] As shown in the above structure, the rear frame 21 in the second carrier 2 and the front frame 11 in the first carrier 1 are both provided with an open structure on the opposite side. The rear frame 21 is connected to the first U-shaped frame 22, and the front frame 11 is mounted with the second U-shaped frame 13 via two L-shaped frames 12. In this way, when the first carrier 1 swings, the second U-shaped frame 13 moves to the inside of the first U-shaped frame 22, thereby avoiding interference problems. This structure makes the distance between the first carrier 1 and the second carrier as small as possible, improves the structural compactness of the first carrier 1 and the second carrier 2, and is also conducive to reducing the load of the power member 6 when it is working.

[0094] During driving, the swing arm 66 of the power member 6 drives the first carrier 1 to perform pitch and swing adjustments through the connecting rod 14 .

[0095] like Figure 4 As shown, the connecting member 8 includes a strap 81 and a connecting cable 82, wherein the hydraulic cylinder 7 is arranged on one end of the first carrier 1 close to the second carrier 2, and the movable end of the hydraulic cylinder 7 is arranged downward; the strap 81 is arranged on one end of the first carrier 1 close to the second carrier 2, and the strap 81 overlaps the second carrier 2; one end of the connecting cable 82 is connected to the first carrier 1, and the other end is connected to the second carrier 2;

[0096] As in the above structure, in order to further reduce the load on the power member 6 and the connecting rod 14, the hydraulic cylinder 7 can be used for auxiliary support to ensure the structural stability of the first carrier 1; specifically, the cylinder body of the hydraulic cylinder 7 can be hinged to the first carrier 1;

[0097] In some embodiments, the second carrier 2 is separated from the first carrier 1. At this time, the first carrier 1 can be adjusted in angle solely by the hydraulic cylinder 7. However, considering the convenience and efficiency of adjustment, as well as the support stability, it is preferred to keep the second carrier 2 connected to the first carrier 1 and adjust the first carrier 1 through the power member 6.

[0098] When the first carrier 1 and the second carrier 2 are parallel, the bridge plate 81 is mounted on the second carrier 2 to bear the weight of the first carrier 1, thereby reducing the load on the power component 6 and improving the stability of the structure.

[0099] The connecting rope 82 is a detachable structure. When the first carrier 1 is connected to the tractor head for towing, the second carrier 2 can be towed by the connecting rope 82. When the first carrier 1 needs to be adjusted, the connecting rope 82 can be removed.

[0100] like Figure 5 As shown, the manifold assembly 5 includes a connecting piece 51, a manifold 52 and a bracket 53, wherein the connecting piece 51 is connected to the first carrier 1 and is located at the bottom of the first carrier 1; the manifold 52 is provided on both sides of the connecting piece 51, and the manifold 52 is connected to the connecting piece 51; a plurality of brackets 53 are provided on both sides of the first carrier 1, corresponding to the pipe openings of the manifold 52, and the brackets 53 are detachably connected to the first carrier 1;

[0101] As shown in the above structure, the manifold assembly 5 is used to connect the liquid outlet pipelines of several fracturing vehicles. It has a plurality of interconnected connecting pieces 51, and each connecting piece 51 is provided with a manifold 52.

[0102] The studio is connected to the liquid outlet pipeline of the fracturing truck through the manifold 52, and the fracturing fluid output from several fracturing trucks is collected through the connecting piece 51 and output through one port;

[0103] Specifically, when assembling the manifold assembly 5, the connecting piece 51 is connected and fixed to the first carrier 1 by fasteners;

[0104] Among them, a bracket 53 is provided on the first carrier 1 corresponding to the manifold 52, which is used to carry the automated connecting pipeline. The pipeline in some manifold assemblies is composed of several sections of pipelines that are movably connected, which has a high degree of adjustment freedom. At this time, it is driven by a hydraulic cylinder to automatically connect the pipeline to the liquid outlet of the fracturing vehicle.

[0105] In this structure, there is no need for the fracturing truck to connect to the manifold 52 through a flexible pipeline. Instead, an automated docking pipeline is provided on the manifold 52 and supported by a bracket 53.

[0106] Specifically, the bracket 53 is configured as a detachable structure. When the fracturing truck needs to use a flexible pipeline to connect the manifold 52 , structural interference can be avoided by disassembling the bracket 53 .

[0107] like Figure 7 and Figure 8 As shown, the pipe rack assembly 9 includes a pipe rack 91 and a cleaning pipeline 92, wherein the pipe rack 91 is arranged on the first carrier 1, and a U-shaped notch 901 is opened on the pipe rack 91 for supporting the functional pipeline 100; the cleaning pipeline 92 is slidably arranged on the first carrier 1 to position and clean the functional pipeline 100;

[0108] As shown in the above structure, the pipe rack 91 is arranged on the upper part of the first carrier 1, and is provided with a U-shaped notch 901 for fixing the functional pipe 100, thereby making full use of the upper space of the first carrier 1 and improving the overall transportation capacity;

[0109] At the same time, a cleaning pipeline 92 is provided on the first carrier 1, which can clean the functional pipeline 100 to prevent the problem of foreign matter clogging the functional pipeline 100 and realize the function of detecting and judging whether the functional pipeline 100 can normally flow the medium; at the same time, it is also used to position the functional pipeline 100 to prevent the functional pipeline 100 from being separated from the pipe rack 91;

[0110] Specifically, the functional pipeline 100 is used for connecting equipment at an oil production site to achieve the transportation of a medium, which is not limited to the transportation of fracturing fluid.

[0111] like Figure 5 、 Figure 6 and Figure 8 The pipe rack assembly 9 further includes a push rod 93, and the cleaning pipeline 92 includes a support 921, a shaft tube 922, and a nozzle 923, wherein the push rod 93 is arranged on the first carrier 1, and the movable end of the push rod 93 abuts the functional pipeline 100; the support 921 is slidably arranged on the first carrier 1; the shaft tube 922 is rotatably connected to the support 921; a plurality of nozzles 923 are arranged on the shaft tube 922, and the plurality of shaft tubes 922 are connected to the shaft tube 922;

[0112] As in the above structure, in the cleaning pipeline 92, the shaft pipe 922 is used to connect the water supply structure, and then the functional pipeline 100 can be flushed through the nozzle 923;

[0113] The shaft tube 922 is rotatably connected to the support 921, and the support 921 is slidably connected to the first carrier 1. In this way, when positioning, the shaft tube 922 and the nozzle 923 can be driven by the support 921 to move toward the functional pipeline 100. After the nozzle 923 is inserted into the shaft tube 922, the end positioning of the shaft tube 922 is achieved, which can prevent the radial movement of the shaft tube 922. At the same time, the shaft tube 922 can be provided with a reducing section to abut against the pipe holder 91 to achieve axial positioning;

[0114] Specifically, the support 921 can be disposed on the first carrier 1 via a movable component such as a slide rail or a guide wheel. Of course, the support 921 is provided with a corresponding positioning mechanism to connect to the first carrier 1, thereby selectively switching between being movable and being fixed relative to the first carrier 1; for example, a bolt is provided as the positioning mechanism;

[0115] When the functional pipeline 100 needs to be removed, a lifting device is required. At this time, one end of the functional pipeline 100 can be positioned by cleaning the pipeline 92, and then the other end of the functional pipeline 100 can be lifted by the push rod 93. At this time, the functional pipeline 100, the shaft tube 922 and the nozzle 923 rotate with the support 921 as the fulcrum, so that the functional pipeline 100 is separated from the U-shaped groove 901, thereby facilitating the lifting work and avoiding problems such as jamming and collision.

[0119] As shown in the above structure, the lifting equipment 10 is used for lifting components to unload functional pipelines and other equipment carried on the first carrier 1. At the same time, it itself is used as a counterweight to avoid the problem of the tail end of the second carrier 2 being lifted up due to its lighter weight when the power part 6 adjusts the posture of the first carrier 1, thereby ensuring the stability and convenience of the application.

[0120] The application method of the fracturing manifold vehicle of the present invention comprises the following steps:

[0121] S1. Hoist the manifold assembly 5 through the first carrier 1 and carry engineering equipment on the first carrier 1;

[0122] S2, connecting the first carrier 1 with a tractor head, thereby towing the first carrier 1 and the second carrier 2 to the construction site;

[0124] S4, using the power member 6 to drive the first carrier 1 to swing up and down with the front wheel set 3 as the axis for leveling;

[0125] S5, connecting the liquid outlet pipe of the fracturing truck to the manifold assembly 5 to perform fluid injection fracturing and mining operations;

[0126] S6. After the extraction is completed, the connection between the fracturing truck outlet pipe and the manifold assembly 5 is released, and the power member 6 drives the first carrier 1 to swing so that one end of the manifold assembly 5 is tilted, thereby emptying the liquid;

[0127] S7, re-mounting the engineering equipment on the first carrier 1, and towing the first carrier 1 and the second carrier 2 by a tractor head.
