Description

Technical Field

[0001] The utility model relates to the technical field of petroleum production and preparation, in particular to a biological pressure-reducing and injection-increasing agent mixing device. Background Art

[0002] Pressure reducing and injection-increasing agents refer to chemical agents used to reduce the pressure and increase the injection of fluids. They are widely used in the field of oil extraction technology. By using pressure reducing and injection-increasing agents, the permeability of oil can be greatly improved, thereby assisting oil extraction operations. Biological pressure reducing and injection-increasing agents are agents in which microbial reagents are added to the pressure reducing and injection-increasing agents to increase the permeability of the reservoir through the decomposition of microorganisms.

[0003] The existing technology often has the following problems when used:

[0004] 1. During the preparation and mixing process of the biological pressure-reducing and injection-increasing agent, it is usually necessary to use a stirring rod to fully stir the mixed reaction liquid. However, the stirring effect of the stirring rod on the mixed reaction liquid near the inner wall of the reactor is relatively low, which makes the dissolution and mixing rate of a small amount of mixed reaction liquid slow, affecting the preparation efficiency and mixing quality of the pressure-reducing and injection-increasing agent;

[0005] 2. In addition, the clay stabilizer and bioactive agent added during the mixed reaction preparation of the biological pressure-reducing and injection-increasing agent are prone to form bottom scale inside the reactor. The formation of bottom scale is not only inconvenient for the subsequent cleaning work inside the reactor, but also causes a waste of some raw materials and reduces the preparation synthesis rate of the pressure-reducing and injection-increasing agent.

[0012] Furthermore, the transmission component includes a transmission gear ring fixedly connected to the upper end of the first rotating shaft, and the upper ends of the two second rotating shafts are fixedly connected with transmission gears, and the two transmission gears are meshed with the transmission gear ring.

DETAILED DESCRIPTION

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1 and Figure 2 As shown, the embodiment of the utility model proposes a biological depressurization and injection agent mixing device, including a reactor 1, a uniform mixing component and a bottom scale cleaning component: a heating base 2 is installed at the bottom of the reactor 1, a feed port 3 is arranged at the top of the reactor 1, a discharge port 4 is arranged at the lower end of the side wall of the reactor 1, a first rotating shaft 5 is rotatably connected to the bottom surface of the reactor 1, a rotating motor 13 is fixedly connected to the top of the reactor 1 through a fixed bracket, and the upper end of the first rotating shaft 5 passes through the top of the reactor 1 and is fixedly connected to the output end of the rotating motor 13 through a coupling;

[0025] The heating base 2 at the bottom of the reactor 1 can be used to heat the reaction liquid inside the reactor and maintain the internal temperature of the reactor 1, which is beneficial to the mixed preparation of the biological pressure-reducing and injection-increasing agent.

[0026] like Figure 1 As shown, the uniform mixing assembly includes a plurality of stirring rods 6 fixedly connected to the first rotating shaft 5;

[0027] The reaction liquid can be stirred and mixed by driving a plurality of stirring rods 6, thereby ensuring that the reaction liquid has a basic degree of mixing uniformity.

[0028] like Figure 1 As shown, two second rotating shafts 7 are rotatably connected to the inner wall of the reactor 1 through a rotating bracket, two supporting plates 8 are fixedly connected to each second rotating shaft 7, a spoiler rod 9 is fixedly connected between the two supporting plates 8, and a transmission component is arranged inside the reactor 1, the transmission component includes a transmission gear ring 14 fixedly connected to the upper end of the first rotating shaft 5, and a transmission gear 15 is fixedly connected to the upper ends of the two second rotating shafts 7, and the two transmission gears 15 are meshed with the transmission gear ring 14;

[0029] During the rotation of the first rotating shaft 5, the transmission gear ring 14 on the first rotating shaft 5 drives the two second rotating shafts 7 to rotate by meshing with the two transmission gears 15, so that the two spoiler rods 9 rotate rapidly, and then the rapidly rotating spoiler rods 9 increase the mixing degree of the part of the reaction liquid close to the inner wall of the reactor 1, thereby improving the dissolution and mixing rate of the reaction liquid and improving the preparation efficiency and mixing quality of the pressure reducing and increasing injection agent.

[0030] like Figure 1 As shown, the bottom scale cleaning assembly includes an adapter block 10 fixedly connected to the lower end of the first rotating shaft 5, and two rotating rods 11 are rotatably connected to the adapter block 10. A scraper 12 is fixedly connected to each rotating rod 11. The side cross-section of the scraper 12 is arranged in a conical structure, and the surface of the scraper 12 is coated with an anti-sticking layer. The ends of the two rotating rods 11 are fixedly connected to bevel gears 16, and the lower end of the inner wall of the reactor 1 is fixedly connected to a bevel gear ring 17, and the two bevel gears 16 are meshed with the bevel gear ring 17. A protective shell 18 is fixedly connected to the lower end of the inner wall of the reactor 1 at the bevel gear ring 17, and a protective ring is slidably connected to the protective shell 18. A through hole is opened on the protective ring, and a sealed bearing is arranged at the through hole, and the rotating rod 11 matches the sealed bearing;

[0031] When the first rotating shaft 5 rotates, the first rotating shaft 5 can synchronously drive the adapter block 10 and the two rotating rods 11 at its lower end to rotate, so that the rotating rod 11 drives the rotating rod 11 to rotate relative to the adapter block 10 through the engagement of the bevel gear 16 and the bevel gear ring 17, and then the scraper 12 can rotate relative to the inner bottom surface of the reactor 1, so that the bottom scale on the inner bottom surface of the reactor 1 can be scraped and cleaned by the scraper 12, and at the same time, the rotating scraper 12 can push the scraped bottom scale to the top of the inner bottom surface of the reactor 1, which is conducive to the mixing and dissolution of the bottom scale and the reaction liquid, thereby facilitating the subsequent internal cleaning work of the reactor 1, and can avoid the waste of raw materials and improve the preparation and synthesis rate of the pressure reducing and increasing agent.

[0032] The detailed working process of the utility model is as follows:

[0033] 1. When the biological pressure-reducing and injection-increasing agent mixing device is used, the raw materials are first introduced into the reactor 1 through the feed port 3, and the rotating motor 13 is started. The first rotating shaft 5 is driven to rotate by the rotating motor 13, so that the several stirring rods 6 on the first rotating shaft 5 stir and mix the reaction liquid. In this process, the transmission gear ring 14 on the first rotating shaft 5 drives the two second rotating shafts 7 to rotate by meshing with the two transmission gears 15, so that the two spoiler rods 9 rotate rapidly, and then the rapidly rotating spoiler rods 9 increase the mixing degree of the part of the reaction liquid close to the inner wall of the reactor 1, thereby improving the dissolution and mixing rate of the reaction liquid, and improving the preparation efficiency and mixing quality of the pressure-reducing and injection-increasing agent;

[0034] 2. When the reaction liquid is uniformly mixed, that is, when the first rotating shaft 5 rotates, the first rotating shaft 5 can synchronously drive the adapter block 10 and the two rotating rods 11 at its lower end to rotate, so that the rotating rod 11 drives the rotating rod 11 to rotate relative to the adapter block 10 through the engagement of the bevel gear 16 and the bevel gear ring 17, and then the scraper 12 can rotate relative to the inner bottom surface of the reactor 1, so that the bottom scale on the inner bottom surface of the reactor 1 can be scraped and cleaned by the scraper 12, and at the same time, the rotating scraper 12 can push the scraped bottom scale to the top of the inner bottom surface of the reactor 1, which is conducive to the mixing and dissolution of the bottom scale and the reaction liquid, thereby facilitating the subsequent internal cleaning work of the reactor 1, and can avoid the waste of raw materials and improve the preparation synthesis rate of the pressure reducing and increasing injection agent.
