Description

Technical Field

[0001] This utility model relates to the field of drilling, and in particular to a stirring device for oil-based drilling fluid thickeners. Background Technology

[0002] Viscosifiers for oil-based drilling fluids are chemical additives that increase the viscosity and shear strength of the drilling fluid. Their core function is to enhance the suspension capacity of the drilling fluid to prevent the settling of weighting agents and drill cuttings, while also improving the sand-carrying capacity to bring drill cuttings out of the wellhead and ensuring that the rheological properties of the drilling fluid meet operational requirements. Common types include organic clay, polymer, and natural or synthetic resins. Organic clay is the most widely used type, which can disperse in the oil phase to form a network structure and is suitable for medium and low temperature drilling scenarios. When using it, the viscosifier needs to be stirred to ensure that it is evenly dispersed in the oil phase. Different types require different stirring equipment and operating requirements, and the selection should be based on the specific drilling conditions.

[0003] In some current production processes, when organic clay is mixed with base oil to achieve a thickening effect, workers usually first pour a small amount of base oil into a small container, then slowly add the organic clay to be added and stir with a hand mixer to premix and make a paste-like premix. This step is to avoid the organic clay powder being poured into a large amount of base oil at once, causing the surface to be quickly coated with oil and the inside to be unable to disperse, thus forming fish-eye-like lumps that are difficult to break down later. After premixing, the workers pour the premix from the small container into a high-speed shear mixing tank, and at the same time pour in enough base oil to mix thoroughly.

[0004] This type of mixing operation requires users to premix separately using a small bucket and to operate the mixer by hand. Furthermore, the premixed material must be manually poured out after mixing, making the operation quite cumbersome.

[0005] Therefore, it is necessary to provide a new stirring device for oil-based drilling fluid thickeners to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a stirring device for oil-based drilling fluid thickeners that integrates a premixed structure above the mixing tank, thereby making it more convenient for users to operate.

[0007] To solve the above-mentioned technical problems, the present invention provides a stirring device for an oil-based drilling fluid thickener, comprising: a stirring tank, a tank cover installed on the top of the stirring tank, and a premixing structure and a shearing structure installed on the surface of the tank cover;

[0008] The shearing structure includes a fixed stator, a shearing impeller, a rotating shaft, a control motor, a rotating blade, and mounting components.

[0009] The premixing structure includes a premixing tank, a connecting pipe fixedly connected to the surface of the tank lid, the inside of the connecting pipe communicating with the inside of the mixing tank, an upper electric valve fixedly connected to the top of the connecting pipe, the top of the upper electric valve fixedly connected to the bottom discharge end of the premixing tank, a second control motor fixedly connected to the top surface of the premixing tank, a vertical shaft fixedly connected to the output end of the second control motor, the vertical shaft rotatably connected to the top wall of the premixing tank, a stirring blade fixedly connected to the end of the vertical shaft inside the premixing tank, and a feed funnel fixedly connected to the top surface of the premixing tank on one side of the second control motor.

[0010] As a further embodiment of this utility model, the inside of the feeding funnel is connected to the inside of the premixing tank, and a top cover is hinged to one outer surface of the feeding funnel, and the top cover matches the feeding funnel.

[0011] Through the above technical solution, this device integrates the premixing structure into the tank lid to facilitate users in quickly premixing organic soil with a small amount of base oil. During operation, a small amount of base oil is poured into the premixing tank, and then the second control motor is turned on to rotate the stirring blades. Simultaneously, organic soil is slowly added from the feed funnel, ensuring thorough premixing within the tank. The remaining large amount of base oil can then be poured into the mixing tank, and the upper electric valve and the first control motor are activated. The opening angle of the upper electric valve can be adjusted according to user needs, thereby controlling the flow rate of the premixed material within the tank. This allows the slowly entering premixed material to gradually and thoroughly mix with the base oil inside. This structural design results in higher overall integration and a more compact structure, while reducing operator inconvenience. The design is reasonable and easy to use.

[0012] As a further embodiment of this utility model, a through groove is provided on the top surface of one side of the bucket lid, and a cover plate is hinged to the top surface of the bucket lid located on one side of the through groove. The cover plate is used to cover the surface of the through groove.

[0013] With the above technical solution, users can open the cover and observe the internal mixing and stirring, and can also pour materials and take samples for observation from there.

[0014] As a further embodiment of this utility model, a discharge pipe is fixedly connected to the bottom surface of the mixing tank, the interior of the discharge pipe is connected to the interior of the mixing tank, a lower electric valve is fixedly connected to the bottom end of the discharge pipe, the mixing tank and the tank cover are fixedly connected by bolts and nuts, and a sealing ring is provided between the mating surfaces of the mixing tank and the tank cover.

[0015] With the above technical solution, before the material needs to be discharged, the user needs to connect and fix the external pipe to the bottom of the lower electric valve so that the material can be discharged into the external pipe after the lower electric valve is opened.

[0016] As a further embodiment of this utility model, the mounting component is fixedly connected to the wall of the bucket lid, the rotating shaft is rotatably connected to the mounting component, the first control motor is fixedly connected to the top surface of the mounting component, the output end of the first control motor is fixedly connected to the top end of the rotating shaft, the fixed stator is disposed on the lower side of the mounting component and the fixed stator is fixedly connected to the mounting component through a fixing column, the shaft body of the rotating shaft is rotatably connected to the fixed stator and the shear impeller is fixedly connected to the bottom end of the rotating shaft, the shear impeller is located inside the fixed stator, and several rotating blades are longitudinally distributed and are all fixedly connected to the rotating shaft.

[0017] Through the above technical solution, the device is equipped with a shearing structure mainly composed of a fixed stator and a shearing impeller, so that the material in the barrel can be fully sheared under the drive of the control motor.

[0018] As a further embodiment of this utility model, a number of support legs evenly distributed around the axis are fixedly connected to the bottom surface of the mixing tank, and a control module is fixedly connected to the surface of one of the support legs. The control motor one, control motor two, upper electric valve and lower electric valve are all electrically connected to the control module.

[0019] Through the above technical solution, the device, by setting up a control module, can facilitate the control of various electrical appliances in the user's structure, thereby better completing the premixing and stirring of materials.

[0020] Compared with related technologies, the stirring device for oil-based drilling fluid thickener provided by this utility model has the following beneficial effects:

Simultaneously, organic soil is slowly added through the feed funnel, ensuring thorough premixing within the tank. The remaining large amount of base oil is then poured into the mixing tank, and the upper electric valve and the first control motor are activated. The opening angle of the upper electric valve can be adjusted according to user needs, controlling the flow rate of the premixed material within the tank. This allows the slowly entering premixed material to gradually and thoroughly mix with the base oil inside. This structural design results in higher overall integration and a more compact structure, while reducing operator inconvenience. The design is reasonable and easy to use.
