Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of controllable, adjustable shock-absorbing support device of fracturing pump discharge flange high-pressure manifold, belong to petroleum low-carbon exploitation field. BACKGROUND

[0002] The development difficulty of domestic conventional oil and gas reservoirs is higher and higher, forcing exploration and development enterprises to carry out more exploration and research on domestic widely distributed, multiple layers, thin and rich layer oil and gas reservoirs (typical shale gas layer). The effective stimulation measure for ultra-low permeability reservoirs such as shale gas is horizontal well factory fracturing technology. Fracturing technology is a technology that uses motor-driven / diesel engine-driven fracturing pumps to inject high-pressure liquid into underground rocks through high-pressure manifolds to create cracks. This process can promote the flow of oil and gas, thereby increasing the production of oil and gas fields.

[0003] Previously, diesel engine-driven fracturing pumps were used for fracturing operations. Now, high-power motor-driven fracturing pumps are used to replace diesel engine-driven fracturing pumps for fracturing operations. The promotion of high-power motor-driven fracturing pumps for fracturing operations reduces fossil energy consumption and carbon emissions.

[0004] In fracturing operations, high-pressure manifolds are "blood vessels" that connect various high-pressure equipment to the wellhead. The fracturing pump discharge flange high-pressure manifold is connected to the fracturing pump. The fracturing pump discharge flange high-pressure manifold vibrates significantly during fracturing operations, especially when high-power motor-driven fracturing pumps are used for fracturing operations. Because of the high power

[0005] , there is no effective support, and the vibration is more intense. High-pressure manifold leaks, punctures, and fractures often occur, which compromises the reliability and safety of the equipment and poses a serious threat to the safety of fracturing personnel.

[0006] According to a large number of field test analyses, the fracturing pump discharge flange high-pressure manifold is in a cantilever beam state (one end is fixed, and the other end is not supported). It vibrates violently under the dual action of mechanical vibration of the fracturing pump and liquid flow pulsation in the high-pressure manifold. One of the main reasons for fracture and other failures is fatigue failure caused by additional loads due to vibration. To reduce the failure and accidents of the fracturing pump discharge flange high-pressure manifold caused by vibration, rigid support and entangled cloth strips are currently used on site to reduce vibration, but the effect is not obvious. The main shortcomings are as follows:

[0007] (1) The rigid support used on site relies solely on a fixed-height support rod for support, which cannot adjust the height of the support. Excessive support will generate additional bending moments, exacerbating the failure of the high-pressure manifold. If the support height is not enough or there is no support, the high-pressure manifold cannot be effectively supported.

[0008] (2) The field support does not design test module and dynamic signal analysis system, and the support force and vibration state are tested and controlled, the vibration state of the high-pressure manifold of the fracturing pump discharge flange is monitored, and the support device is ensured to reach the best support state;

[0009] (3) The field support device does not design a damping device, and the vibration of the high-pressure manifold of the fracturing pump discharge flange cannot be effectively absorbed, and the ideal damping effect cannot be achieved;

[0010] (4) The field support device does not design a loosening prevention device, and the support device is prone to support failure under the severe vibration of the high-pressure manifold of the fracturing pump discharge flange;

[0011] (5) The field support device does not design a labor-saving device, and the field use is time-consuming and labor-intensive, which is extremely inconvenient.

[0012] Therefore, controllable and adjustable damping measures need to be taken for the high-pressure manifold of the fracturing pump discharge flange, so as to improve the reliability and safety of the equipment and ensure the safety of fracturing operation and personnel.

[0013] Therefore, it is of great significance to design a controllable and adjustable damping support device for the high-pressure manifold of the fracturing pump discharge flange. Content of the utility model

[0014] The utility model aims at using a high-power electric fracturing pump to replace a diesel fracturing pump for fracturing operation, popularizing high-power electric fracturing pump fracturing operation, reducing fossil energy consumption and carbon emission. When the high-power electric fracturing pump is used for fracturing operation, high-pressure manifold leakage, puncture and fracture often occur due to severe vibration, and a controllable and adjustable damping support device for the high-pressure manifold of the fracturing pump discharge flange needs to be designed, which can effectively support the high-pressure manifold of the fracturing pump discharge flange, so as to improve the reliability and safety of the equipment and ensure the safety of fracturing operation and personnel.

[0015] The technical scheme adopted by the utility model is:

[0016] A controllable and adjustable damping support device for the high-pressure manifold of the fracturing pump discharge flange mainly comprises a base 1, a coarse adjustment screw pair lifting mechanism 2, a fine adjustment scissor lifting mechanism 3, a digital display force measuring module 4, a damping device 5, a loosening prevention device 6, a high-pressure manifold 7 of the fracturing pump discharge flange, a vibration sensor 8 and a dynamic signal analysis system. The dynamic signal analysis system is connected to the dynamic signal analysis system through the digital display force measuring module 4 and the vibration sensor 8.

[0017] Preferably, the base 1 is welded with a reinforcing rib 12 and a support rod 13 on a bottom plate 11, and a sleeve 14 is welded on the support rod 13. The structure ensures that the base 1 has good strength, processability and economy.

[0018] Preferably, the coarse adjustment screw pair lifting mechanism 2 rotates the handle 22 through the crowbar 311, drives the rotating sleeve 21 on the thrust ball bearing 24 to rotate, thereby realizing the lifting movement of the screw rod 23.

[0019] Preferably, the fine adjustment scissor lifting mechanism 3 drives the lead screw 305 through the crowbar 311, thereby dragging the outer front connecting rod 301, the outer rear connecting rod 302 and the inner connecting rod 304, so that the "X" shaped connecting rod 303 realizes the opening and closing adjustment.

[0020] When adjusted to the required position, locking is performed through the front locking nut 306 and the rear locking nut 307, so as to complete the accurate lifting of the fine adjustment scissor lifting mechanism 3. The front cover plate 308, the rear cover plate 309 and the side cover plate 310 are hingedly installed on the fine adjustment scissor lifting mechanism 3, prevent the entry of rain, sand and other impurities, and facilitate the lubrication and rust prevention of the fine adjustment scissor lifting mechanism 3.

[0021] Preferably, the damping support device base 1 is arranged between the bottom support structure of the fracturing truck equipment and the fracturing pump discharge flange high-pressure pipe manifold 7.

[0022] The digital display force measuring module 4 is arranged, and the support force data measured by the digital display force measuring module 4 and the vibration data measured by the vibration sensor 8 on the fracturing pump discharge flange high-pressure pipe manifold 7 are transmitted to a dynamic signal analysis system, so as to determine the optimal support force and ensure that the support device reaches the optimal support state.

[0023] Preferably, the damping device 5 is coupled in a clamp type by the upper sleeve 53 and the lower sleeve 51, is convenient to assemble and disassemble, and is internally provided with a semicircular groove, so that the damping inner tube 52 filled with gas / liquid can be arranged in the semicircular groove, can effectively absorb the vibration of the fracturing pump discharge flange high-pressure pipe manifold, and achieves an ideal damping effect, so that the device can match the fracturing pump discharge flange high-pressure pipe manifold with different vibration intensities.

[0024] Preferably, the anti-loosening device 6 adopts various anti-loosening designs, including locking screw 61 locking anti-loosening, trapezoidal thread self-locking anti-loosening and double-nut anti-loosening, so as to ensure that the support device can effectively support under the severe vibration of the fracturing pump discharge flange high-pressure pipe manifold, thereby significantly improving the stability and reliability of the support. The opening locking washer 62 is arranged on the screw rod 23 of the coarse adjustment screw pair lifting mechanism 2, and the opening direction of the opening locking washer 62 is opposite to the unscrewing direction of the locking disc 63. When the screw rod 23 is subjected to external force, the opening locking washer 62 blocks the loosening of the locking disc 63, thereby effectively preventing the locking disc 63 from being loosened by itself. Meanwhile, the locking disc 63 adopts a principle similar to the double-nut anti-loosening, and further enhances the anti-loosening performance.

Through the above working process, the support force of the fracturing pump discharge flange high pressure manifold can be controlled, and the fracturing pump discharge flange high pressure manifold can be fully and effectively supported, so as to improve the reliability and safety of the fracturing equipment and ensure the safety of the fracturing operation and personnel.​
