Description

Technical Field

[0001] The invention belongs to the technical field of fiber conveying, and specifically refers to a fiber multi-stage hydration dispersion conveying and filling device. Background Art

[0002] Fiber-sand fracturing technology, as an efficient means of increasing oil and gas well production, aims to inject fracturing fluid containing fibers and proppants into the formation to form fracture channels with high conductivity, thereby significantly improving the seepage capacity and production of oil and gas wells. Since its introduction into field applications, this technology has been tested in practice for more than ten years and has achieved significant success in many oil and gas field projects, demonstrating its unique advantages in improving recovery.

[0003] However, despite the obvious advantages of fiber-sand fracturing technology, its large-scale promotion faces many challenges. The most critical problem is the lack of ideal fiber dispersion and precise injection equipment during on-site construction. Existing equipment is insufficient in terms of uniform fiber dispersion and precise control of injection, which makes it easy for fibers to form "fiber clusters" during injection. This will not only cause drastic fluctuations in sand injection pressure and increase the risk of sand plugging, but may also block pipelines in subsequent flowback and production stages, adversely affecting the long-term production increase effect of oil and gas wells. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a fiber multi-stage hydration dispersion conveying and filling equipment, which realizes efficient dispersion and hydration of the fiber through a spraying roller dispersion mechanism. The spiral dragon is not only responsible for transporting the fiber from the reservoir box to the hydration tank, but its rotation can also drive the second dispersion blade to rotate, thereby enhancing the mixing effect of the fiber and water. The rotation of the fiber dispersion hydration tank further drives the first dispersion blade to rotate, and the rotation directions of the two dispersion blades are opposite. This design greatly promotes the uniform dispersion of the fiber in the water and improves the hydration efficiency.

[0008] Furthermore, a first sealing ring is sleeved on the upper end of the outer wall of the fiber dispersion and hydration tank, and a second sealing ring is sleeved on the lower end of the outer wall of the fiber dispersion and hydration tank.

[0009] Furthermore, the spray assembly includes a water tank, which is sleeved on the outer wall of the fiber dispersion and hydration tank, and a booster water pump 2 is provided at the lower end of the water tank, and a pumping end of the booster water pump 2 is through-connected to the lower end of the side wall of the water tank, an inner wall tube is provided on the inner wall of the fiber dispersion and hydration tank, and a spray head is installed on the side wall of the inner wall tube, and the output end of the booster water pump 2 is through-connected to one end of the output pipe, and the other end of the output pipe is through-connected to the side wall of the inner wall pipe.

[0013] (1) In order to solve the problem that the existing equipment has deficiencies in the uniform dispersion and precise control of fiber injection, which leads to the formation of "fiber clusters" during the injection process, which not only causes violent fluctuations in the sand injection pressure but also increases the risk of sand blockage, the present invention provides a spray-type roller dispersion mechanism to achieve efficient dispersion and hydration of the fibers. The spiral dragon is not only responsible for transporting the fibers from the reservoir box to the hydration tank, but its rotation can also drive the second dispersion blade to rotate, thereby enhancing the mixing effect of the fibers and water. The rotation of the fiber dispersion hydration tank further drives the first dispersion blade to rotate, and the two dispersion blades rotate in opposite directions. This design greatly promotes the uniform dispersion of the fibers in the water and improves the hydration efficiency.

[0014] (2) Through the spray-type roller dispersion mechanism, the uniformity of the fiber solution is further ensured by the stirring action of the stirring rod in the stirring tank, so that the fiber can be fully dissolved and evenly distributed in the solution, providing high-quality raw materials for subsequent processing.

[0015] (3) Through the spray-type counter-roll dispersion mechanism, the design of the spray head enables water to be sprayed evenly on the fibers, which helps to break the entanglement and agglomeration between the fibers and reduce the occurrence of agglomeration.

[0016] (4) Through the spray-type roller dispersion mechanism, the rotation of the propeller in the conveying pipeline not only helps to promote the flow of the fiber solution, but also disperses the solution again during the conveying process, ensuring that the fiber solution still maintains a high degree of uniformity and dispersion when it reaches the sand mixing tank.

[0017] (5) Through the spray-type roller dispersion mechanism, the water consumption is small, the dispersion is thorough, and the fiber decomposition efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
