Description

Technical Field

[0001] The utility model belongs to the technical field of plugging agent filling, and in particular relates to a device for filling a polymer plugging agent for heavy oil hot mining. Background Art

[0002] In the application field of heavy oil thermal mining polymer plugging agents, improving the plugging effect and ensuring good adhesion between the plugging agent and the formation are key technologies for improving oil field recovery. Currently, after being injected into the ground, the heavy oil thermal mining polymer plugging agent uses the thermal energy of the formation to solidify the solution in the formation, forming a high-strength, high-temperature resistant concrete-like solid material. This solid material effectively blocks the crossflow and water outlet channels, thereby reducing the water content of the oil well and improving the ultimate recovery rate of the heavy oil field.

[0003] However, in actual application, there is a common technical problem. When the plugging agent is injected into the formation cracks, the dust, debris and other impurities that may exist in the cracks will affect the bonding strength between the plugging agent and the formation, resulting in poor plugging effect. In field applications in some heavy oil fields, after the plugging agent is injected, the dust in the formation cracks is not effectively removed, and the bonding between the plugging agent and the formation is not strong. As a result, the plugging agent will fall off or the plugging effect will be weakened after a period of time. This not only reduces the efficiency of the plugging agent, but also increases the maintenance cost of the oil field.

[0004] In order to solve the above problems, the utility model proposes an improved device for filling polymer plugging agents for heavy oil hot mining. Utility Model Content

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0022] like Figure 1-3 As shown, a device for filling a polymer plugging agent for heavy oil hot mining is provided. The steps for injecting the plugging agent into the gap are as follows:

[0023] First, solid compounds and water are poured into the feed port in a proportional manner. After a certain period of stirring, they are pumped out from the silo by a high-pressure pump truck. In this process, while two silos are feeding the pump truck, the other two silos are simultaneously adding materials and water to mix the chemical reagents. After being pressurized by the high-pressure pump truck, the pump truck injects it into the wellhead.

[0024] After being injected into the ground, the plugging agent utilizes the thermal energy of the formation to solidify the solution in the formation, forming a high-strength, high-temperature resistant concrete-like solid material, which effectively blocks the crossflow and water outlet channels, reduces the water content of the oil well, and improves the ultimate recovery rate of the heavy oil field;

[0025] The conveying process is as follows:

[0026] The device comprises a liquid outlet pipe 1, the outer side of the liquid outlet pipe 1 is connected to a plurality of liquid discharge hoses 2, and each liquid discharge hose 2 is equipped with a solenoid valve 3;

[0027] By setting the solenoid valve 3, when the liquid outlet pipe 1 receives the plugging agent of the filling structure described below, the plugging agent can be transferred to the liquid discharge hose 2. Different liquid discharge hoses 2 are inserted into different gaps, and the flow rate of different liquid discharge hoses 2 and whether different liquid discharge hoses 2 discharge liquid can be controlled by controlling the liquid discharge hoses 2.

[0028] The outer side of the liquid outlet pipe 1 is further connected to a connecting fixed pipe 12 , and the end of the connecting fixed pipe 12 away from the liquid outlet pipe 1 is connected to a rotating disk 8 , and a filling structure is installed on the side of the rotating disk 8 away from the connecting fixed pipe 12 .

[0029] Refer to the attached Figure 1-2The filling structure includes a fan 4 and a liquid pump 6, and conductive holes 14 are provided at both ends of the rotating disk 8. The output end of the fan 4 is connected to one of the conductive holes 14 through a first connecting hose 5, the output end of the liquid pump 6 is connected to the other conductive hole 14 through a second connecting hose 7, and the connecting fixed pipe 12 is connected to one of the conductive holes 14;

[0030] When the liquid pump 6 is driven, the external plugging agent can be transported to the rotating disk 8 through the second connecting hose 7, and then transmitted to the connecting fixed pipe 12 through the conducting hole 14 on the rotating disk 8, so that the rotating disk 8 transmits the plugging agent to the liquid outlet pipe 1;

[0031] An adjustment mechanism is installed on the outer side of the rotating disk 8, and the adjustment mechanism is used to adjust the connection between the fixed tube 12 and any one of the two conducting holes 14;

[0032] Refer to the attached Figure 2 The adjusting mechanism includes a driven gear 9 fixed to the outside of the rotating disk 8, one side of the driven gear 9 is meshed with a driving gear 10, and the adjusting mechanism also includes a motor 11, the output end of the motor 11 is connected to the driving gear 10;

[0033] When the motor 11 is driven, it can drive the driving gear 10 to rotate, and through the meshing connection between the driving gear 10 and the driven gear 9, the driving gear 10 can drive the driven gear 9 to rotate, and then drive the rotating disk 8 to rotate. By setting the motor 11, the output end of the motor 11 will only rotate half a circle at a time, and will reverse after rotating half a circle, thereby preventing the first connecting hose 5 and the second connecting hose 7 from being entangled;

[0034] A connecting structure is installed between the rotating disk 8 and the connecting and fixing pipe 12 .

[0035] Refer to the attached Figure 3 The connecting structure includes a guide groove 13 provided on one side of the rotating disk 8 near the conducting hole 14, and the conducting hole 14 is provided inside the rotating disk 8 and located at both ends of the guide groove 13. Furthermore, the guide groove 13 is arranged in an arc shape with an arc angle of 180°. By frying the perilla seeds, the guide groove 13 can limit the rotating disk 8 and the output end of the motor 11 to rotate only half a circle. If the rotation continues, a jam will occur.

[0036] When the rotating disk 8 rotates, the connecting and fixing tube 12 does not move, so that one of the conducting holes 14 on the rotating disk 8 rotates to be disconnected from the connecting and fixing tube 12, while the other conducting hole 14 rotates to be connected to the connecting and fixing tube 12;

[0037] A magnet 15 is fixed to one end of the connecting and fixing tube 12 close to the rotating disk 8, and a magnet 15 is also fixed inside the guide groove 13 and on the side located outside the conducting hole 14 and close to the connecting and fixing tube 12. When the connecting and fixing tube 12 rotates until it abuts against the conducting hole 14, the magnets 15 provided on both sides can cause the connecting and fixing tube 12 and the conducting hole 14 to be attracted to each other. Furthermore, the magnetic poles of the two magnets 15 are opposite. Through this arrangement, the connecting and fixing tube 12 and the conducting hole 14 can be attracted to each other. If the magnet 15 on the connecting and fixing tube 12 close to the conducting hole 14 is the S pole, the magnet 15 on the conducting hole 14 close to the connecting and fixing tube 12 will be the N pole.

[0038] The working principle of this utility model is:

[0039] First, the motor 11 is controlled so that the output end of the motor 11 drives the rotating disk 8 to rotate until the conducting hole 14 connected to the first connecting hose 5 is connected to the connecting fixed pipe 12. At this time, the fan 4 can be driven to blow air into the first connecting hose 5, and then blow it through the conducting hole 14 to the connecting fixed pipe 12 and the liquid outlet pipe 1, and then blow it through the liquid outlet pipe 1 to the drain hose 2. The arrangement of the drain hose 2 allows the drain hose 2 to pre-blow air into each gap, thereby removing dust and the like in the gap and preventing the sprayed plugging agent from being loosely adhered to the gap due to dust and the like.

[0040] After the blowing is completed, the motor 11 can be driven so that the output end of the motor 11 drives the driving gear 10 to reverse until the conductive hole 14 connected to the second connecting hose 7 on the rotating disk 8 is connected to the connecting fixed pipe 12, and then the liquid pump 6 is driven to make the liquid pump 6 suck the plugging agent and transport it to the second connecting hose 7 and the liquid outlet pipe 1, and then transport it to each drainage hose 2 through the liquid outlet pipe 1 to seal and irrigate the gap.

[0041] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
