Description

Technical Field

[0001] The invention relates to the field of petrochemical industry, and in particular to an oil field flow regulating device based on an energy-saving motor control system. Background Art

[0002] In the fluid transportation work in the oil field, the viscosity of the fluid itself will affect the flow rate of the fluid, thereby affecting the flow volume of the fluid in the pipeline within a certain period of time. When the fluid viscosity is high, the fluid flow rate is slow and the flow rate is low. When the fluid viscosity is low, the fluid flow rate is fast and the flow rate is high.

[0003] In order to increase the conveying speed of the fluid in the pipeline and increase the flow rate of the fluid, a viscosity reducer is usually added to the pipeline. By mixing the fluid and the viscosity reducer, the total viscosity of the fluid is reduced, so as to achieve the purpose of increasing the fluid flow rate and changing the fluid flow rate. The fluid extracted from the deep oil field has different components of crude oil in different locations, and the viscosity of the fluid in different areas of the pipeline is also different. It is necessary to add a viscosity agent in the pipeline to monitor the viscosity of the fluid. However, the existing fluid viscosity agent has a limited measurement stroke. In order to adapt to fluids with large flow rates, a low-sensitivity viscosity detector is needed to reduce the measurement error. In order to adapt to fluids with small flow rates, a high-sensitivity viscosity detector is needed to improve the measurement accuracy. Therefore, it is not possible to rely solely on a simple viscosity monitoring system and a flow control system to perform a specified range viscosity monitoring function for fluids with different flow rates, and thus it is not possible to accurately adjust the flow of fluids with large flow changes.

[0032] like Figure 8 and Fig. 9 As shown, the adjusting unit includes a first bevel gear 301, a second rotating shaft 302, a second bevel gear 303, a third bevel gear 304, a third rotating shaft 305, a fourth bevel gear 306, a rotating disk 307 and a baffle 308; the front end of the first rotating shaft 104 is fixedly connected to the first bevel gear 301; the lower side of the upper fixing frame 101 is rotatably connected to the second rotating shaft 302; the lower side of the second rotating shaft 302 is rotatably connected to the mixing chamber 4; the lower end of the second rotating shaft 302 is rotatably connected to the storage chamber 5; the upper end of the second rotating shaft 302 is fixedly connected to the first bevel gear 301; the lower end ... fixedly connected to the second rotating shaft 302; the lower end of the second rotating shaft 302 is fixedly connected to the first bevel gear 301; the lower end of the second rotating shaft 302 is fixedly connected to the second rotating shaft 302; the lower end of the second rotating shaft 302 is fixedly connected to the first bevel gear 301; the lower end of the second rotating shaft 302 is fixedly connected to the first bevel gear 301; the lower end of the second rotating shaft 302 is fixedly connected to the first bevel gear 301; the lower end of the second rotating shaft 302 is fixedly connected to the first bevel gear 301; the lower end of the second rotating shaft 302 is fixedly connected to the first bevel gear 301; the lower end of the second rotating Second bevel gear 303; the first bevel gear 301 is meshed with the second bevel gear 303; the lower end of the second rotating shaft 302 is fixedly connected to the third bevel gear 304; the middle part of the front side of the storage chamber 5 is rotatably connected to the third rotating shaft 305; the front end of the third rotating shaft 305 is fixedly connected to the third bevel gear 304; the second bevel gear 303 is meshed with the third bevel gear 304; the middle part of the third rotating shaft 305 is fixedly connected to a turntable 307; the outer surface of the turntable 307 is fixedly connected to a plurality of baffles 308; the baffles 308 are close to the liquid outlet of the liquid outlet pipe 52.

[0033] First, the fluid flows along the input pipe 2, the left side of the U-shaped pipe 1, the mixing chamber 4, the right side of the U-shaped pipe 1 and the output pipe 3 in sequence. At the same time, the viscosity monitoring unit monitors the viscosity of the fluid flowing through the left side of the U-shaped pipe 1 and the right side of the U-shaped pipe 1 respectively. When the viscosity of the fluid needs to be adjusted, the external viscosity reducing agent liquid supply device conveys the viscosity reducing agent to the storage chamber 5 through the liquid inlet pipe 51, and the storage chamber 5 releases the viscosity reducing agent into the mixing chamber 4 through the liquid outlet pipe 52. When the fluid flows through the mixing chamber 4, the fluid is mixed with the viscosity reducing agent in the mixing chamber 4 to achieve the effect of reducing the viscosity. The viscosity monitoring unit compares the viscosity change degree of the fluid after the viscosity adjustment process, and feeds back to the energy-saving motor 102 of the motor control unit. The energy-saving motor 102 drives the adjustment unit through the motor control unit to adjust the release amount of the viscosity reducing agent released from the liquid outlet pipe 52 to ensure that the viscosity of the fluid is stable within the specified range, thereby ensuring that the flow rate of the fluid is adjusted between the stable numerical range.

[0034] During operation of the viscosity monitoring unit, the fluid first flows from the wide side of the guide tube 206 through the narrow side of the guide tube 206, so that the flow rate of the fluid flowing through the guide tube 206 is higher than the flow rate of the fluid flowing through the outside of the guide tube 206, so that a pressure difference occurs between the fluids on the inside and outside of the guide tube 206. Under the influence of the pressure difference between the fluids on the inside and outside of the guide tube 206, the fluid flowing through the guide tube 206 pushes the outer pressure plate 209 to drive the third slide bar 208, the inner pressure plate 210 and the pressure spring 211 to move toward the vertical plate 213. Since fluids of different viscosities exert different resistances on the movement of the inner pressure plate 210, the corresponding data of the fluid viscosity is obtained by sensing the tensile strength of the pressure spring 211 through the tension sensor 207, and the purpose of detecting the viscosity change of the fluid is achieved by monitoring the change in the tensile strength of the pressure spring 211.

[0035] When the fluid flowing through the guide tube 206 passes between the inner pressure plate 210 and the vertical plate 213 , the flow velocity of the fluid flowing through the guide tube 206 is further increased, so that the pressure difference of the fluid on both sides of the guide tube 206 is amplified, thereby improving the accuracy of viscosity monitoring of the fluid.

[0036] When the flow rate of the fluid passing through the output pipe 3 increases greatly, the output shaft of the energy-saving motor 102 drives the first rotating shaft 104 to rotate, the first rotating shaft 104 drives the spur gear 105 to rotate, the spur gear 105 engages with the gear rod 107 to drive the adjusting slider 106 to move along the first mounting frame 103, and the adjusting slider 106 drives the first sliding bar 203, the second mounting frame 204 and the second sliding bar 205 to move along the first rod sleeve 201 and the second rod sleeve 202, so that the second mounting frame 204 drives the guide tube 206 and the activity monitoring component to move away from the energy-saving motor 102 along the fourth sliding bar 212, so that the inner pressure plate 210 moves away from the vertical plate 213. At the same time, as the fluid flow rate increases, the fluid pressure difference between the inner and outer sides of the guide tube 206 gradually increases, so that the inner pressure plate 210 moves closer to the vertical plate 213 again, so that despite the large changes in the fluid, the distance between the inner pressure plate 210 and the vertical plate 213 maintains the same floating spacing, further improving the accuracy of viscosity monitoring of the fluid.

[0037] When the flow rate of the fluid passing through the output pipe 3 increases greatly, the output shaft of the energy-saving motor 102 drives the first rotating shaft 104 to rotate, the first rotating shaft 104 drives the first bevel gear 301 to rotate, the first bevel gear 301 engages with the second bevel gear 303 to drive the second rotating shaft 302 to rotate, the second rotating shaft 302 drives the third bevel gear 304 to rotate, the third bevel gear 304 engages with the fourth bevel gear 306 to drive the third rotating shaft 305 and the turntable 307 to rotate, the turntable 307 drives the baffle 308 to rotate around the axis of the third rotating shaft 305, so that the baffle 308 reduces the coverage area of ​​the liquid outlet pipe 52 and increases the release amount of the viscosity reducer of the liquid outlet pipe 52, so that under the control of the energy-saving motor 102, the adjustment work of the activity monitoring component and the adjustment work of the fluid viscosity are carried out synchronously, ensuring that the viscosity of the fluid is stable within the specified range, thereby ensuring that the flow rate of the fluid is adjusted between the stable numerical range.

[0038] Example 2

[0039] like Figure 1-Figure 11 As shown, this embodiment is a further optimization made on the basis of the embodiment, and also includes an auxiliary mixing unit. The auxiliary mixing unit is provided on the storage chamber 5, and the auxiliary mixing unit includes an annular slider 401, an annular fixing frame 402, a blade 403 and a torsion spring 404; the outer surface of the storage chamber 5 is slidably connected with the annular slider 401; the outer side of the annular slider 401 is welded with an annular fixing frame 402; the outer surface surrounding the annular fixing frame 402 is rotatably connected with a plurality of blades 403 through a rotating shaft; a torsion spring 404 is fixedly connected between each blade 403 and the annular fixing frame 402, and the torsion spring 404 is sleeved on the outer surface of the rotating shaft of the adjacent blade 403.

[0040] When the storage chamber 5 releases the viscosity reducer into the mixing chamber 4 through the liquid outlet pipe 52, the fluid rushing downward into the mixing chamber 4 from the left side of the U-shaped pipe 1 pushes the left blade 403 to drive the annular fixing frame 402 to rotate around the axis of the annular slider 401. At the same time, the fluid flowing from the right side of the mixing chamber 4 to the right side of the U-shaped pipe 1 pushes the right blade 403 to drive the annular fixing frame 402 to rotate around the axis of the annular slider 401, so that all the blades 403 rotate counterclockwise to stir and mix the viscosity reducer and the fluid flowing through the mixing chamber 4, thereby improving the mixing efficiency of the viscosity reducer and the fluid.

[0041] When the flow rate of the fluid passing through the output pipe 3 increases greatly, the fluid hitting the blade 403 increases the thrust on the blade 403, causing the blade 403 to drive the torsion spring 404 to rotate around the axis, increasing the vertical angle of the blade 403, reducing the effective lateral contact area between the blade 403 and the fluid, improving the flow performance of the fluid, reducing interference with the fluid flow, and ensuring stable flow of the fluid.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
