Description

Technical Field

[0001] The utility model relates to the technical field of temporary plugging liquid supply devices, in particular to a continuous temporary plugging agent liquid supply device. Background Art

[0002] Temporary plugging agent is a substance that can temporarily reduce the permeability of the formation or temporarily plug the high permeability oil layer. After being mixed with water-soluble polymers and injected into the well, it can quickly form a thin and dense temporary plugging zone of the oil layer under the action of pressure difference. After a certain period of time, it can be unblocked by itself or manually.

[0003] In the prior art, it is necessary to mix a temporary plugging agent with a water-soluble polymer to form a temporary plugging liquid, so as to temporarily reduce the permeability of the formation or temporarily plug a high permeability oil layer. During the mixing process, the temporary plugging liquid needs to be fully mixed. Once the mixing is uneven, the temporary plugging effect will be poor. In addition, during the mixing process, the temporary plugging agent and the water-soluble polymer are easy to adhere to the inner wall of the stirring tank, resulting in a poor effect of the stirred temporary plugging liquid, which requires the staff to clean up the temporary plugging liquid on the inner wall. This is not only very troublesome, but also makes it impossible to continuously supply the temporary plugging liquid. Therefore, we propose a continuous temporary plugging agent supply device. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. It is necessary to mix a temporary plugging agent with a water-soluble polymer to form a temporary plugging liquid, so as to temporarily reduce the permeability of the formation or temporarily plug a high-permeability oil layer. During the mixing process, the temporary plugging liquid needs to be fully mixed and uniform. Once the mixing is uneven, the temporary plugging effect will be poor. In addition, during the mixing process, the temporary plugging agent and the water-soluble polymer are easy to adhere to the inner wall of the stirring tank, resulting in a poor effect of the stirred temporary plugging liquid, which requires the staff to clean up the temporary plugging liquid on the inner wall. This is not only very troublesome, but also makes it impossible to continuously supply the temporary plugging liquid.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] The technical effect of adopting the above further solution is that the cover can be effectively driven to rise by the hydraulic push rod, thereby facilitating maintenance of the stirring device.

[0010] As a preferred solution of the utility model, the inner bottom wall of the mixing kettle is provided with an arc to facilitate the temporary blocking liquid to flow downward, and a liquid storage tank for conveying the temporary blocking liquid is fixedly connected to the bottom of the mixing kettle, and a connecting hole is provided at the connection between the liquid storage tank and the mixing kettle.

[0012] The technical effect of adopting the above further solution is: through the setting of the electric valve, it is possible to effectively prevent the raw materials from falling into the liquid storage tank and being unable to be fully stirred before stirring.

[0013] As a preferred solution of the utility model, three supporting legs for maintaining the stability of the mixing kettle are equidistantly arranged at the bottom of the mixing kettle, and the supporting legs are fixed to the bottom of the mixing kettle by bolts.

[0014] As a preferred solution of the utility model, the feed solenoid valve penetrates the inner wall of the mixing kettle, and the mixing kettle is connected to an external feed device.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] In the utility model, through the setting of the stirring device, the stirring motor can effectively drive the stirring roller to rotate, so as to fully stir the temporary plugging agent and the water-soluble polymer. At the same time, the stirring roller drives the scraper to rotate, so that the temporary plugging agent and the water-soluble polymer cannot adhere to the inner wall of the mixing kettle, so that the temporary plugging agent and the water-soluble polymer can be fully and fully stirred, so there is no need to stop the mixing kettle, and the mixing work can be carried out continuously, achieving the effect of continuous liquid supply.

Scrapers 32 for cleaning the inner wall of the mixing kettle 1 are symmetrically arranged on both sides of the stirring roller 31. The top of the stirring roller 31 is fixedly connected to the output end of the stirring motor 33. The stirring motor 33 can drive the stirring roller 31 to rotate. The stirring motor 33 passes through the cover body 34 and is fixedly connected to the horizontal part of the cover body 34.

[0027] Example 2

[0028] like Figure 1-3 As shown, the outer periphery of the cover body 34 is symmetrically provided with supporting lugs 341, and the bottom of the supporting lugs 341 is fixedly connected with the output end of the hydraulic push rod 342, and the hydraulic push rod 342 pushes the supporting lug 341 to move up and down. The fixed end of the hydraulic push rod 342 is provided with a mounting block 343 for supporting the hydraulic push rod 342, so as to facilitate the lifting and opening of the cover body 34. The inner bottom wall of the mixing kettle 1 is provided with an arc for the temporary blocking liquid to flow downward. The bottom of the mixing kettle 1 is fixedly connected with a liquid storage tank 4 for conveying the temporary blocking liquid out, and the connection between the liquid storage tank 4 and the mixing kettle 1 is provided with a connecting hole. In order to facilitate the temporary blocking of liquid from flowing into the liquid storage tank 4, a liquid outlet solenoid valve 41 is arranged on the periphery of the liquid storage tank 4, a pump body 42 for infusion is fixedly connected to the inner bottom wall of the liquid storage tank 4, and the output pipe of the pump body 42 is connected to the liquid outlet solenoid valve 41, and an electric valve 43 for isolating the liquid storage tank 4 is installed in the interlayer of the mixing kettle 1, and three supporting legs 11 for maintaining the stability of the mixing kettle 1 are equidistantly arranged at the bottom of the mixing kettle 1, and the supporting legs 11 are fixedly connected to the bottom of the mixing kettle 1 by bolts, and the feed solenoid valve 2 passes through the inner wall of the mixing kettle 1, and the mixing kettle 1 is connected to the external feeding device.

[0029] The working process of the utility model is as follows: when a continuous temporary plugging agent liquid supply device is used to continuously supply temporary plugging liquid, first, the feed solenoid valve 2 is connected to the raw material conveying device, and then the feed solenoid valve 2 is opened to allow the raw material to enter the interior of the mixing kettle 1. At the same time, the stirring motor 33 drives the stirring roller 31 to rotate, so that the temporary plugging agent and the water-soluble polymer entering the mixing kettle 1 are mixed together. At the same time, the scraper 32 scrapes the inner wall of the mixing kettle 1 to prevent the temporary plugging agent and the water-soluble polymer from adhering to it. After sufficient mixing, the electric valve 43 is opened to allow the temporary plugging liquid at the bottom to flow into the liquid storage tank 4. At this time, the liquid outlet solenoid valve 41 and the pump body 42 are opened to transport the temporary plugging liquid to the place where temporary plugging is required. When the temporary plugging liquid at the bottom is transported out, the upper feed solenoid valve 2 continues to transport the raw material from the outside and stirs at the same time, so as to achieve the effect of continuous liquid supply. The utility model can effectively prevent the temporary plugging agent and the water-soluble polymer from adhering to the inner wall during the mixing process of the temporary plugging liquid through design, and can fully mix them, thereby achieving the effect of continuous liquid supply.
