[0002] The original injection preparation, dissolution and maturation technology for onshore tertiary oil recovery, intelligent energy recovery and other purposes has a long process and large equipment footprint. For example, the daily preparation of 50m 3 High concentration mother liquor covers an area of ​​200m 2 Above, several hundred m 3 / dThe preparation of mother liquor requires a larger area. The process is long, the equipment is large, the installed units are large, the power consumption is high, and the management and maintenance are difficult.

[0032] With reference to the accompanying drawings, Figure 1 A schematic diagram of the injection process of the smart energy oil displacement agent for the existing oil field injection system; Figure 2 It is a schematic diagram of the front cross-sectional structure of a horizontal axis embodiment of a high-speed water hammer compound overweight mechanism of the present invention; Figure 3 It is a schematic diagram of the front cross-sectional structure of the vertical axis embodiment of the high-speed water hammer compound overweight mechanism of the present invention.

[0033] In a specific embodiment, Figure 2 As shown, a high-speed water hammer compound overweight mechanism includes a stator barrel 1 and a rotor 2. The core shaft 201 of the rotor 2 is sealed and supported in the stator barrel 1 through a bearing 3 and a bearing seat, and the stator barrel 1 is installed on a frame. An impeller group 204 and an overweight bed 205 are installed on the core shaft 201. A spacer ring 8 for sealing and isolation is arranged in the middle of the stator barrel 1. The spacer ring 8 isolates the impeller group 204 and the overweight bed 205 and divides the stator barrel 1 into a stirring chamber 102 and an overweight chamber 103. The stator barrel 1 is provided with an input port 101 for water and a mixed liquid of the main agent and the auxiliary agent on the side wall of the stirring chamber 102, and an output port 104 for outputting the matured mother liquid is provided on the side wall of the super-heavy chamber 103 of the stator barrel 1.

The power input can be driven directly by a motor or driven by a belt.

[0034] Through the composite super-heavy mechanism mainly composed of the stator barrel 1 and the rotor 2, the water source is pumped or sucked into the composite super-heavy mechanism by negative pressure, mixed with the main agent and auxiliary agent sent by the feeder to form a mixed liquid, and enters the stirring chamber 102 through the input port 101. After high-speed stirring by the impeller group 204, macroscopic mixing and microscopic dissolution; enters the super-heavy chamber 103 through the core shaft connecting hole group and is infiltrated, filtered and matured by the super-heavy bed 205. The volume of the composite super-heavy mechanism of the present invention is reduced from more than 100 cubic meters of 4 dispersion and maturation tanks to less than 1 cubic meter of reactor, the volume is reduced by more than 100 times, and the dissolution and maturation speed is shortened from 18-24 hours to less than 10 minutes, which improves the efficiency by 100 times. Compared with the original stirring speed of 40-50r / min, in this embodiment, the stirring blades and super-heavy bed are installed on the high-speed rotating power shaft of about 1000r / min, and the acceleration exceeds 10,000, realizing self-priming feeding, high-speed water hammer stirring, mixing and dissolving, and super-heavy penetration, maturation and filtration. The composite overweight mechanism of the present invention can complete the preparation, mixing, dispersion, dissolution and maturation of the solution of the smart energy oil displacement agent or other insoluble solvents, while reducing the size of the equipment and the occupied space, while increasing the speed of the dissolution and maturation process and improving production efficiency.

[0035] In a specific embodiment of the present invention, Figure 2 As shown, the mandrel connecting hole group includes a mandrel input hole 202, a mandrel output hole 203 and an axial hole 207 that are interconnected. The axial hole 207 is coaxially arranged at the center of the shaft section of the mandrel 201 located in the stirring chamber 102 and the super-heavy chamber 103, and the outer end of the axial hole 207 is sealed by an axial plug 206 with a sealing ring. The mandrel input hole 202 is radially arranged at the position of the mandrel 201 in the stirring chamber 102 near the spacer ring 8, and several mandrel input holes 202 are evenly distributed around the circumference. The mandrel output hole 203 is radially arranged at the root of the mandrel 201 at the super-heavy bed 205, and several groups of mandrel output holes 203 are evenly distributed around the circumference and output the stirred and dispersed mixed liquid to the super-heavy bed 205.

[0036] The core shaft connecting hole group consisting of the core shaft input hole 202, the core shaft output hole 203 and the axial hole 207 cleverly connects the stirring chamber 102 and the super-heavy chamber 103, so that the mixed liquid stirred and dispersed by the impeller group 204 can be output to the root of the super-heavy bed 205 for super-heavy maturation.

[0037] In a specific embodiment of the present invention, Figure 2As shown, the bearing seat includes a first bearing seat 4, a second bearing seat 5 and a third bearing seat 6. The two first bearing seats 4 are respectively arranged behind the bearings 3 at both ends and support the bearings 3. The second bearing seat 5 is arranged outside the overweight cavity 103. The second bearing seat 5 seals the gap between the core shaft 201 and the stator barrel 1 through the first sealing rings 501 at the inner diameter and the outer diameter respectively. The third bearing seat 6 is arranged outside the stirring cavity 102. The third bearing seat 6 seals the gap between the core shaft 201 and the stator barrel 1 through the second sealing rings 601 at the inner diameter and the outer diameter respectively.

[0038] Specifically, if Figure 2 As shown, an annular groove is provided in the middle of the third bearing seat 6 , the input port 101 corresponds to the annular groove, and a low-pressure zone input hole 602 facing the stirring chamber 102 is provided at the bottom of the annular groove.

[0039] Specifically, if Figure 2 As shown, a spacer sleeve 7 is provided between the inner side wall of the third bearing seat 6 and the spacer ring 8, and a spoiler and a spoiler ring for high-speed water hammer are provided on the inner side wall of the spacer sleeve 7. The spoiler and the spoiler ring are provided on the outer periphery of the impeller group 204 to disturb and block the liquid flow stirred by the impeller group 204. Of course, when the spacer sleeve 7 is not provided, a spoiler and a spoiler ring can also be provided on the inner wall of the stator barrel 1 accordingly.

[0040] By setting the second bearing seat 5 and the third bearing seat 6, it is convenient to isolate the bearing chamber where the bearing 3 is located from the stirring chamber 102 and the super-heavy chamber 103; by setting the annular groove and the low-pressure zone input hole 602, it is convenient to introduce the mixed liquid introduced by the input port 101 into the low-pressure zone of the stirring chamber 102, which can form a negative pressure suction feed, saving the traditional method of jet pump feeding. By setting the spacer 7, it is convenient to ensure the distance between the inner wall of the third bearing seat 6 and the spacer ring 8. When the number of impellers of the impeller group 204 is replaced, it is necessary to replace the spacers 7 of different lengths at the same time. The inner wall of the spacer 7 is provided with a baffle and a baffle ring, which is convenient to block the mixed liquid stirred at high speed by the impeller of the impeller group 204, increase the disturbance water hammer effect, and improve the dissolution efficiency.

[0041] In a specific embodiment of the present invention, Figure 2 As shown, the impeller assembly 204 includes a booster impeller unit and a stirring impeller unit connected in series axially. The impeller blade group pressure angle of the booster impeller unit is large, which is convenient for boosting and pumping the mixed liquid, and a negative pressure is formed at the low-pressure area input hole 602, which is convenient for suction feeding. Moreover, the number of impellers of the booster impeller unit and the stirring impeller unit and the structural form of the impeller blades can be adjusted by replacement.

[0042] In a specific embodiment of the present invention, the channel gap of the supergravity reaction bed of the supergravity bed 205 can be adjusted by replacing the supergravity reaction bed assembly. The micropores of the supergravity reaction bed have the function of homogenizing and filtering the slaking liquid, and the filter particle size of the flow channel Φ0.15mm can be adjusted. The water hammer agitator is coaxial with the supergravity reaction bed, and the supergravity stirring speed is 300-970r / min; the supergravity acceleration is 200-1000m / s2, and the speed range can be appropriately adjusted according to the degree of solvent solubility. The gravity reaction bed with an acceleration of 200-1000m / s2, the increase of circumferential speed and centrifugal force, makes the mixed liquid quickly dispersed, broken and membraned in the filler in the supergravity reaction bed, so that the continuously updated micro-elements are multiplied; the tortuous flow channel further intensifies the rapid increase of the membrane interface update and specific surface multiples of mass transfer and diffusion exchange; and pushes it to the outer edge of the rotor. In this process, the liquid phase in the mixed liquid is in liquid-solid and liquid-liquid contact under the conditions of high dispersion, high turbulence, strong mixing and rapid mass transfer exchange at the interface, which greatly enhances the mixing, dissolution and maturation efficiency.

[0043] The degree of maturation, efficiency and dissolution uniformity of the maturation liquid can be adjusted by the number, shape, rotation speed and super-heavy bed parameters of the impellers; the particle size of the solid phase in the maturation liquid can be controlled by adjusting the pores of the filler in the super-heavy reaction bed, replacing the filter of the system.

[0044] In a specific embodiment of the present invention, Figure 3 As shown, the stator barrel 1 and the rotor 2 are both arranged vertically, the stirring chamber 102 and the super-heavy chamber 103 are arranged in series up and down, and the top protruding end of the core shaft 201 is connected to the driving unit. The driving unit includes a motor 10, which is vertically installed on one side of the stator barrel 1, and the output shaft of the motor 10 is connected to the pulley connected to the pulley on the top of the core shaft 201 through a transmission belt.

[0045] Specifically, if Figure 3 As shown, an exhaust pipe 105 for exhaust is arranged on the top of the stirring chamber 102, and a baffle is added at the bottom of the exhaust pipe 105, so that the exhaust pipe 105 can be convenient for exhausting the air mixed in during feeding; a passing screen 208 is arranged below the stirring chamber 102, and the cylindrical passing screen 208 is sleeved on the core shaft input hole of the core shaft 201. The passing screen 208 filters the mixed liquid entering from the stirring chamber 102 into the super-heavy chamber 103, so as to prevent the mixed liquid that is not fully macro-mixed and micro-dissolved from entering the super-heavy chamber 103.

[0046] By arranging the stator barrel 1 and the rotor 2 vertically, the installation area of ​​the mechanism can be effectively reduced relative to the horizontal axis, and is suitable for applications with limited installation area such as offshore platforms in offshore oil fields.

[0047] The high-speed water hammer composite super-heavy mechanism of the present invention is mainly composed of a stator barrel 1 and a rotor 2. The water source is injected and pumped to the composite super-heavy mechanism, mixed with the auxiliary agent to form a mixed liquid, and enters the stirring chamber 102 through the input port 101. After high-speed stirring by the impeller group 204, macroscopic mixing and microscopic dissolution; through the core shaft connecting hole group, it enters the super-heavy chamber 103 and is infiltrated, filtered and matured by the super-heavy molecules of the super-heavy bed 205. The composite super-heavy mechanism of the present invention can reduce the volume of the equipment and the occupied space while completing the solution preparation, mixing, dispersion, dissolution and maturation of the smart energy oil-displacing agent or other insoluble solvents, while increasing the dissolution and maturation process speed and improving production efficiency. In addition, the core shaft connecting hole group composed of the core shaft input hole 202, the core shaft output hole 203 and the axial hole 207 cleverly connects the stirring chamber 102 and the super-heavy chamber 103, so that the mixed liquid stirred and dispersed by the impeller group 204 is output to the root of the super-heavy bed 205 for super-heavy maturation. The second bearing seat 5 and the third bearing seat 6 are provided to facilitate the isolation of the bearing chamber where the bearing 3 is located from the stirring chamber 102 and the super-heavy chamber 103; the annular groove and the low-pressure zone input hole 602 are provided to facilitate the introduction of the mixed liquid introduced by the input port 101 into the low-pressure zone of the stirring chamber 102, which can form a negative pressure suction feed, saving the traditional method of jet pump feeding. A baffle and a baffle ring are provided on the inner wall of the spacer 7 or the stator barrel 1 to facilitate blocking the mixed liquid stirred at high speed by the impeller of the impeller group 204, increase the disturbing water hammer effect, and facilitate improving the dissolution efficiency. The degree of maturation, efficiency and dissolution uniformity of the maturation liquid can be adjusted by the number, shape, rotation speed of the impeller and the super-heavy bed parameters; the solid phase particle size of the maturation liquid can be controlled by adjusting the pores of the filler in the super-heavy reaction bed, replacing the filter of the system. By arranging the stator barrel 1 and the rotor 2 vertically, the installation area of ​​the mechanism can be effectively reduced relative to the horizontal axis, and is suitable for applications with limited installation area such as offshore platforms in offshore oil fields.
