Description

Technical Field

[0001] The utility model relates to the technical field of plugging agent production, in particular to a stirring device for producing plugging agent while drilling in oil mines. Background Art

[0002] Oilfield drilling plugging agent is mainly made of natural raw materials and produced through scientific formula. Its main ingredients are highly active humates and their derivatives, cellulose, plant gum, pentosan, etc. It has the appearance of a flowable solid powder and is a plugging material used to reduce filtration and protect reservoirs in drilling fluids. The consolidated anti-plugging agent is a new type of plugging agent that is easy to use, has high sedimentation stability, high acid solubility, high consolidation strength, and multiple consolidation methods. Since the consolidated plugging agent is made by crushing and mixing a variety of raw materials, the existing consolidated plugging agent mixing device may cause uneven mixing of the raw materials during use due to the different densities of the mixed raw materials during the stirring process of the device, which can easily lead to a decrease in the quality of the plugging agent.

[0003] The utility model "A Drilling Plug Production Device" with patent number CN211384661U includes a production box with a cylindrical hollow structure, a production stirring mechanism installed on the top of the production box, a discharge funnel with a discharge control valve connected to the bottom of the production box, a feed funnel connected to the circumferential outer wall of the production box, and a production stirring mechanism including a sealing cover and a stirring shaft. A stirring motor is installed on the sealing cover, and the output shaft of the stirring motor passes through the center of the sealing cover and extends into the production box to be coaxially connected to the stirring shaft. The utility model can fully stir the drilling plugging agent by installing a stirring motor on the top surface of the production box and cooperating with the stirring shaft and stirring ring, saving human resources. Different raw materials can be added to the feed funnel. The sealing cover is threadedly connected to the production box by fixing bolts that pass through the fixing holes and screw holes in sequence. After long-term use, the sealing cover can be opened to clean the inside of the production box, which is more hygienic.

[0004] The above scheme can fully stir the drilling plugging agent through the cooperation of the stirring shaft and the stirring ring. However, the densities of various raw materials are different. During the stirring process of the device, the raw materials may be unevenly mixed up and down, which may easily cause the quality of the plugging agent to deteriorate. Therefore, we propose a stirring device for the production of oil and mine drilling plugging agents. Utility Model Content
