Description

Technical Field

[0001] This invention belongs to the technical field of weighting agent production equipment, specifically an integrated processing device for weighting agents. Background Technology

[0002] Currently, in oil drilling, when drilling into high-pressure brine or high-pressure oil / gas formations, the specific gravity of the drilling mud must be appropriately increased. This is achieved by adding a certain amount of weighting agent. Weighting agents have high density and are typically composed of materials such as barite, hematite, and quartz sand mixed in a specific ratio. However, existing drilling mud formulations often exhibit poor rheological properties and instability. When the weighting agent particles are coarse and have a narrow particle size distribution, the settling velocity is high, suspension stability deteriorates, and inter-particle bridging is severe, leading to increased frictional resistance in the drilling fluid. Excessive fine particles in the weighting agent result in a large specific surface area, severe surface effects, and poor flowability. When the weighting agent particle size distribution in the system is reasonable, with fine particles distributed among coarse particles, along with the action of treatment agents, the frictional effect caused by bridging between coarse particles can be reduced, improving flow. Especially in weighting agent production, the processes of raw material crushing, grinding, weighing, proportioning, and activation are complex, intermittent, inefficient, and time-consuming.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] In this invention, a grading and re-sorting component is vertically fixed to the upper end of the fixed base via an upper connecting frame. This component can classify the prepared material according to mesh size, effectively separating small particles from large particles. This ensures that during solution mixing, larger particles are preferentially used for initial mixing, while smaller particles, with their high filling rate and good flowability, are added in appropriate amounts to prepare a high-density drilling fluid. Furthermore, an inner grinding seat is provided inside the storage cylinder, and grinding balls are rotatably mounted within this seat. These grinding balls slide laterally along the threaded rod through the threaded engagement of an outer sleeve and a threaded rod, adjusting the grinding particle size. Meanwhile, a flow control and discharge device is also provided on the storage cylinder. This device can control the flow of the prepared material, allowing it to enter the long or short extrusion gap between the grinding balls and the inner extrusion grinding seat in a proportional manner. This results in the prepared material in the storage cylinder exhibiting a particle size distribution of either a large or small particle size. A sealing disc is also slidably installed inside the outer mixing cylinder. Especially in the initial stage of weighting agent preparation, when large-particle prepared material is initially added, the sliding action of the sealing disc pressurizes and stirs the main solution in the outer mixing cylinder, improving its fusion effect.

[0053] Please see Figure 1 In this embodiment of the invention, an integrated processing apparatus for weighting agents includes:

[0054] Fixed base 1;

[0055] The upper frame 2 is vertically fixed to one side of the upper end face of the fixed base 1;

[0056] The grading and re-sorting component 4 is vertically suspended above the fixed base 1 via the upper connecting frame 2. The upper end of the grading and re-sorting component 4 is horizontally connected to a conveying pipe 21, and one end of the conveying pipe 21 is connected to an external feeding tank.

[0057] The liquid storage tank 3 is vertically embedded and fixed on the fixed base 1, and the liquid storage tank 3 contains a fixed amount of solution body;

[0058] The mixing and grading assembly 5 is horizontally mounted on the upper surface of the fixed base 1, located below the grading and recombination assembly 4. One end of the grading and recombination assembly 4 is connected to the mixing and grading assembly 5, and a discharge pipe 31 is horizontally and sealed below the mixing and grading assembly 5. One end of the discharge pipe 31 is connected to the lower end of the liquid storage tank 3.

[0059] The external discharge pipe 6 is vertically connected to the side of the mixing and grading assembly 5 away from the liquid storage tank 3.

[0060] In this embodiment, the hierarchical reselection component 4 includes:

[0061] Mounting bracket 41;

[0062] The storage cylinders 42 are arranged in a circular array, and each of the storage cylinders 42 is vertically fixed on the mounting frame 41.

[0063] The flow control and drainage device 7 is provided in a one-to-one correspondence with each of the fixed storage cylinders 42. The flow control and drainage device 7 is laterally connected above the fixed storage cylinders 42, and the upper end of the flow control and drainage device 7 is connected to the conveying pipe 21.

[0064] An internal grinding and grading device 8 is installed inside the storage cylinder 42. After the prepared material is ground in a completely non-uniform manner, the internal grinding and grading device 8 re-sorts and grades the prepared material.

[0065] Multiple vertically arranged side connecting pipes 43 are provided, with one end of each side connecting pipe 43 connected to a respective grading chamber of the internal grinding and grading device; and

[0066] The converging pipe 44 is vertically arranged below the middle of the mounting frame 41, and the other end of each side connecting pipe 43 is connected to the converging pipe 44.

[0067] In a preferred embodiment, the flow control drainage device 7 includes:

[0068] Fixed cavity component 71;

[0069] The main drain fan 72 is rotatably disposed above the interior of the fixed cavity 71;

[0070] The partition plate 73 is obliquely fixed inside the middle side of the fixed cavity 71, dividing the fixed cavity 71 into two chambers vertically; and

[0071] The diversion page 74 is rotatably disposed at the conveying end of the main discharge page 72. One end of the diversion page 74 is connected to the upper cavity of the fixed cavity 71. It should be noted that the conveying end of the diversion page is on the side away from the main discharge page, while the conveying end of the main discharge page is on the same side. This allows the preparation material conveyed in the fixed cavity to be branched and conveyed from the left and right sides of the fixed cavity. The relative conveying ratio of each branch on the left and right sides of the fixed cavity is controlled by the variable speed rotation of the diversion page (low speed, medium speed, or high speed rotation).

[0072] In this embodiment, the internal grinding and grading device 8 includes:

[0073] The inner extrusion grinding seat 81 is coaxially disposed on the upper side inside the storage cylinder 42, and the inner wall of the cross-section of the inner extrusion grinding seat 81 has an arc-shaped structure.

[0074] A central cover 83 is coaxially connected above the inner extrusion base 81, and the upper end of the central cover 83 is connected to the fixed cavity 71.

[0075] The grinding ball 82 is rotatably disposed within the inner grinding seat 81;

[0076] The layered sieves 84 are multiple sieves arranged vertically and evenly, and each of the layered sieves 84 is fixed at an incline inside the storage cylinder 42.

[0077] A central shaft 87 is rotatably mounted through the layered screen 84. A built-in motor is installed inside the lower side of the storage cylinder 42. The output end of the built-in motor is connected to one end of the central shaft 87 for transmission via a transmission belt.

[0078] The axial leaf plates 85 are arranged in multiple sets arranged vertically, and each of the axial leaf plates 85 is arranged in a circumferential array on the central axis 87.

[0079] A top positioning rod 86, vertically extending through the axial leaf plate 85, is slidably and relatively limited. One end of the top positioning rod 86 is connected to a roller and abuts against the layered screen 84.

[0080] The support spring 88 is sleeved on the top rod 86. Under the cooperation of the inner extrusion grinding seat and the grinding ball, the prepared material is ground and then classified by mesh through the layered sieve to effectively separate small particles from large particles.

[0081] In this embodiment, a threaded rod 89 is laterally rotatably provided on the upper inner side of the storage cylinder 42, and an outer sleeve is provided on the grinding ball 82. The outer sleeve is slidably connected to the threaded rod 89 through threaded engagement. That is to say, the grinding ball can be laterally displaced relative to the inner grinding seat, so that the grinding gaps on both sides of the grinding ball act as the limit grinding size of the prepared material, and can gradually increase from the short-distance grinding gap to the long-distance grinding gap. Thus, the prepared material has a variety of particle sizes with different mesh sizes during grinding preparation. That is, if the mesh size of the prepared material after grinding is A (A is a non-limit mesh value), then it has particles with mesh values ​​from A-5 to A+5, and can be mixed and prepared simultaneously.

[0082] In this embodiment, the summing pipe 44 is configured as a multi-pipe socket structure, and one end of the summing pipe 44 is connected to the mixing and grading component 5 through a diffuser.

[0083] In a preferred embodiment, the mixing and grading component 5 includes:

[0084] External mixing cylinder 51;

[0085] The sealing disc 52 is slidably and sealingly disposed on the side of the outer mixing cylinder 51 away from the outer discharge pipe 6;

[0086] The telescopic guide 53 is symmetrically connected to the outer mixing cylinder 51 laterally, and the output end of the telescopic guide 53 is connected to the sealing disc 52;

[0087] A telescopic stirring roller 54 is coaxially mounted on the sealing disc 52 and can rotate relative to it. One end of the telescopic stirring roller 54 is disposed inside the outer mixing cylinder 51 via an outer connecting ring seat.

[0088] The diffuser baffle 55 is horizontally arranged on the upper side inside the outer mixing cylinder 51. Especially in the early stage of preparation and processing, the relative sliding action of the sealing disc can pressurize and stir the main body of the solution in the outer mixing cylinder, thereby improving its fusion effect.

[0089] In this embodiment, the cross-section of the diffuser baffle 55 is arc-shaped, and the diffuser baffle 55 is configured as a two-section retractable leaf plate structure, which can effectively control the dispersion of the prepared material into the solution body.

[0090] Specifically, in the weighting agent processing, the weighting agent preparation material can be separately conveyed to the storage cylinder. At this time, the relative displacement between the grinding ball and the inner extrusion grinding seat is adjusted by the rotation of the threaded rod. The variable speed rotation of the diversion page (low speed, medium speed or high speed rotation) controls the relative conveying ratio of each branch on the left and right sides of the fixed cavity, so that the preparation material can flow into the long-distance extrusion grinding gap or short-distance extrusion grinding gap between the grinding ball and the inner extrusion grinding seat and pass through the stratified screen for classification by mesh size, effectively separating small particles from large particles. At this time, the liquid storage tank conveys the main body of the solution to the outer mixing cylinder. Large particles are used for preliminary mixing first, and then small particles are added in appropriate amounts due to their high filling rate and good fluidity to prepare a high-density drilling fluid. Especially in the filling of small particles, it is characterized by a distribution of particles with multiple different mesh sizes, and the filling and fusion effect is better.

[0091] In summary, the content of this invention is not limited to the above-described embodiments. Those skilled in the art can easily propose other embodiments within the technical guiding principles of this invention, but such embodiments are all included within the scope of this invention.
