Problems solved by technology

[0004] However, in the crankshaft plunger pump of the prior art, the stroke is short, the number of reversing times is large, the plunger moves frequently, and the life of the wearing parts is short, for example, the service life of the valve seat, valve and valve rubber at the fluid end Only tens of hours; In addition, the output pressure and flow coverage of this crankshaft plunger pump is relatively narrow. To improve the coverage, it is necessary to replace the fluid end with a different cylinder diameter; , the fracturing fluid is discharged before it is fully inhaled, resulting in low suction efficiency and low work efficiency; in addition, the fracturing pump is integrated with a crankshaft, power input gear, connecting rod, hydraulic end box and seat, etc. The structure is complex, the manufacturing cost is high, and the disassembly and maintenance are inconvenient; in addition, the power input gear rotates at high speed and heavy load, which has high requirements for lubrication and cooling, and it is necessary to arrange a complex lubrication system and corresponding cooling system

Embodiment 1

[0073] Such as Figure 1 to Figure 4 As shown, a hydraulic pump station skid 1 includes a plurality of oil supply units, each oil supply unit includes a power element 101, a transfer case 103 and two hydraulic oil pumps 104a, 104b, the power element 101 and the transfer case 103 The input end is connected by transmission, and the transfer case 103 has two output ends, and the output ends of the transfer case 103 are respectively connected by transmission to the hydraulic oil pumps 104a and 104b.

[0074] In the prior art, the displacement of the hydraulic oil pumps 104a and 104b cannot be selected arbitrarily, especially when selecting a hydraulic oil pump with a large displacement, it is often limited by factors such as technical maturity and price. The hydraulic pump station of this embodiment In the skid 1, one power element 101 is used to drive two hydraulic oil pumps 104a, 104b, and the transmission is carried out through the transfer case 103. In the case of using a smal...

Embodiment 2

[0090] Such as Figure 1 to Figure 9 As shown, a hydraulic oil tank, the hydraulic oil tank 2 includes a box body 201, a radiator 202 and a radiator oil pump 203, the suction end of the radiator oil pump 203 is connected to the box body 201, the discharge end of the radiator oil pump 203 is connected to the radiator 202, and the heat dissipation The discharge end of the device 202 is connected with the box body 201. In the traditional hydraulic profile control pump, the radiator 202 is connected to the oil return pipeline 111, while the hydraulic oil tank 2 in this embodiment adopts bypass heat dissipation. On the one hand, the radiator 202 is protected from the impact of the returning hydraulic oil. , it is convenient to match a reasonable heat dissipation oil pump 203 according to heat dissipation requirements, so as to efficiently dissipate heat from hydraulic oil.

[0091] There are multiple radiators 202 and cooling oil pumps 203 , and the radiators 202 correspond to the...

Embodiment 3

[0103] Such as Figure 10 to Figure 13 As shown, a hydraulic pressure-driven pump hydraulic skid 3 includes a frame 301 and three working units connected to the frame 301 . The working unit includes a hydraulic cylinder 302 and a first hydraulic end and a second hydraulic end symmetrically arranged on both sides of the hydraulic cylinder 302 . The hydraulic cylinder 302 includes a hydraulic piston rod 303, the hydraulic piston rod 303 has a first output end and a second output end oppositely arranged, the first output end is connected to the first hydraulic end, and the second output end is connected to the second hydraulic end .

[0104] The frame 301 is installed on the upper side of the base 10, and the base 10 is used to provide support for the frame 301, the slurry suction pipeline system 7, the slurry discharge pipeline system 8 and the spraying system 9.

[0105] In this embodiment, there are three working units, but it should be noted that there may be 2 to 10 workin...

Abstract

The invention discloses a hydraulic pump station skid and a hydraulic fracture displacement pump with the hydraulic pump station skid, and relates to the technical field of petroleum equipment. The hydraulic pump station skid comprises power elements, transfer cases and multiple hydraulic oil pumps, the power elements are in transmission connection with the input ends of the transfer cases, each transfer case is provided with multiple output ends, and the output ends of the transfer cases are in transmission connection with the hydraulic oil pumps correspondingly. In the hydraulic pump stationskid, one power element is adopted to drive the multiple hydraulic oil pumps, transmission is achieved through the transfer cases, and under the condition that a small number of power elements is used, the maximum displacement of the hydraulic fracture displacement pump can be increased by selecting the conventional hydraulic oil pumps. The hydraulic fracture displacement pump comprises the abovehydraulic pump station skid.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a hydraulic pump station skid and a hydraulic pressure drive pump. Background technique [0002] The pressure flooding technology is to use the conventional fracturing construction technology to inject a large volume of high-efficiency oil-displacing agent into the formation to recover the energy of the formation, and use the displacement and replacement of the high-efficiency oil-displacing agent to tap the remaining oil and improve the degree of reservoir production. Measures to increase production technology. In the practice of pressure-flooding operations in Daqing Oilfield in my country, the cumulative oil increase in the stage of pressure-flooding technology is four times that of conventional fracturing measures, and the effectiveness has been fully verified. [0003] At present, some oil fields use fracturing trucks for pressure-driving operations. Common frac...
