Description

Technical Field

[0001] The invention relates to the technical field of petroleum exploration equipment, and in particular to a single-tube in-situ turbidity reduction and cooling device for a fracturing proppant. Background Art

[0002] Fracturing proppant is the most important supporting agent in the formation fracturing technology of oil exploration and development. During the production process of fracturing proppant, a large amount of dust will be generated, and dust affects the key indicator of proppant turbidity. The increase of dust will not only change the form of fracturing sand-carrying fluid, making the sand-carrying fluid viscous and turbid, affecting its carrying capacity for proppant and affecting the proppant entering the target gap, but also the floating dust formed will seriously pollute the environment and construction site, and the solid and dust pollution brought about will endanger the occupational health of construction workers; therefore, it is necessary to reduce the generation of dust during the production process.

[0003] At present, the cooling of fracturing proppants is mainly carried out by a single-cylinder cooler, which uses air or cold water interlayer to cool the materials in the cylinder. The materials enter from one end of the cylinder (kiln head) and move downward along the cylinder through rotation and gravity. At the same time, the fan system blows or sucks cooling air from the top (kiln head) or cools water from the bottom (kiln tail) cold water interlayer. The cooling temperature gradually passes through the material layer and cools it down to near room temperature; the cooled materials are discharged from the outlet at the bottom (kiln tail). However, when the existing single-drum cooler is in operation, the lifting height of the drum is low. When the proppant particles are lifted to 1 / 3 of the drum height, the particles begin to fall and lift, and the single lifting plate can carry less ceramsite. The ceramsite entering the cooling drum is basically in a process of continuous falling and rolling along the drum wall, and friction powder and powder removal occur continuously, generating a large amount of dust; the dust and the finished proppant are piled up and moved together, and due to the friction static electricity, the dust is tightly adsorbed on the surface of the proppant particles, resulting in difficulty in powder removal; at the same time, after cooling, the product agglomerates are difficult to eliminate, and the turbidity of the finished proppant cannot be reduced, affecting the quality of the finished product; larger and harder agglomerates will also cause a large amount of difficult-to-handle residues on the sieve when the finished product is screened, affecting production efficiency. In addition, during the cooling process of the existing single-drum cooler, parameters such as air flow, cooling water flow and temperature difference, material inlet and outlet, and drum inclination will affect the cooling effect. In order to achieve the best effect, precise control and adjustment are required. There are many factors affecting the cooling effect, and control is difficult. Summary of the invention

DETAILED DESCRIPTION

[0056] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0057] like Figures 1 to 6As shown, an embodiment of the present invention provides a fracturing proppant single-drum in-situ turbidity reduction and cooling device, comprising: a support 1, a drum 2, a drive system 3, a water cooling system 4 and a fan system 5; the support 1 is supported at the bottom of the drum 2, and is used to support the drum 2 to rotate. The drum 2 is arranged on the support 1, and can be supported by the support 1 to rotate; the drum 2 comprises: a drum 2-1, a bucket-type material lifter 1 2-3, a bucket-type material lifter 2-4, a plate-type material lifter 2-5 and a transmission member 2-2; one end of the drum 2-1 has a feed port for inputting granular materials; the other end of the drum 2-1 has a discharge port for outputting processed materials. The bucket-type material lifter 2-3 is fixedly arranged on the inner wall of the drum 2; there are multiple bucket-type material lifters 2-3; multiple bucket-type material lifters 2-3 are arranged in an array along the circumferential direction and axial direction of the cylinder 2-1; the bucket-type material lifter 2-3 rotates with the cylinder 2-1, rotates to the lower part of the cylinder 2-1, fills the material, and conveys the material to a height of more than 2 / 3 of the height of the cylinder 2-1, and then the material gradually flows out from the bucket-type material lifter 2-3. The material is basically in a relatively static state in the bucket-type material lifter 2-3, and the friction between them is small, which can increase the lifting height, and the material is scattered from a higher position, which increases the contact time with the airflow, improves the cooling efficiency, and at the same time increases the drop height of the sintered particles, which is easy to break up and eliminate the agglomeration.

[0058] There is a predetermined distance between the bucket-type material lifter 2-3 and the kiln head end of the cylinder 2-1; the predetermined distance is preferably 1 / 3 of the length of the cylinder 2-1. After research and testing, the position where the proppant particles produce turbidity in the traditional single-cylinder cooler starts approximately at 1 / 3 of the length of the cylinder 2-1 from the feed port (kiln head). From this position, the surface of the proppant formed after preliminary cooling has basically solidified. Due to the large amount of mutual friction between the proppant particles after the surface solidification during the rolling and forward process, a large amount of fine dust is generated, which is the main source of turbidity of the finished particles. The setting of the bucket-type material lifter 2-3 and the bucket-type material lifter 2-4 can reduce the mutual friction between the proppant particles and reduce the generation of dust.

[0059] The bucket-type material lifter 2-4 is fixedly arranged on the inner wall of the drum 2, and there are multiple bucket-type material lifters 2-4; the multiple bucket-type material lifters 2-4 are alternately distributed with the bucket-type material lifter 1 2-3 in the circumferential direction; the arrangement of the bucket-type material lifter 1 2-3 and the bucket-type material lifter 2-4, because the proppant particles are basically in a static state in the bucket-type material lifter 1 2-3 and the bucket-type material lifter 2-4, the friction between them is greatly reduced, thereby reducing the raw powder and powder loss caused by excessive friction, and further reducing the turbidity of the proppant particles. The bucket-type material lifter 1 2-3 and the bucket-type material lifter 2-4 increase the lifting height of the proppant particles, and increase the dust height of the cooling proppant particles. The higher the height of the proppant particles going up along the drum wall, the longer the time they are in contact with the cooling airflow after being lifted down, which increases the cooling efficiency; at the same time, it also increases the falling height of the sintered particles, which is conducive to eliminating agglomeration.

[0060] The edges of the bucket-type lifting device 2-4 on both sides have sharp corners; when the proppant particles have high agglomeration strength and large volume, sharp corners are added to the edges of the bucket-type lifting device 2-4, thereby greatly enhancing the force and strength to break up the agglomerates.

[0061] The plate-type feeder 2-5 is fixedly arranged on the inner wall of the drum 2; there are multiple plate-type feeders 2-5; multiple plate-type feeders 2-5 are alternately distributed with bucket-type feeders 1 2-3 and / or bucket-type feeders 2-4 along the axial direction of the cylinder 2-1; the alternating use of the plate-type feeders 2-5 is used to improve the surface roundness and sphericity of the proppant particles, eliminate the burrs and uneven shapes on the surface of the particles, and improve the quality of the proppant. Because after the proppant particles are injected into the formation, they will use their spherical shape to roll and migrate in the formation cracks, and their migration distance will be greatly increased, which is conducive to achieving the results of formation fracturing. The protrusions, burrs and irregular shapes naturally formed on the surface of the proppant particles during the cooling process will affect the sphericity of the particles. Therefore, the appropriate amount of mutual rolling and friction of the particles in the cylinder 2-1 will eliminate the burrs and protrusions on the surface of the particles, and form finished particles with good roundness and sphericity.

[0062] The plate-type feeder 2-5 is alternately distributed with the bucket-type feeder 1 2-3 and / or bucket-type feeder 2-4 along the axial direction of the cylinder 2-1. The bucket-type feeder 1 2-3 and the bucket-type feeder 2-4 are used to reduce the friction and powder removal rate of the proppant particles, thereby reducing the turbidity; and the plate-type feeder 2-5 is used to make the proppant particles rub against each other and shape them, eliminate the burrs and protrusions on the surface of the particles, and improve the roundness and sphericity of the ceramsite. The transmission component 2-2 is fixedly mounted on the outer wall of the drum 2, and is used for transmission connection with the drive system 3; preferably, the transmission component 2-2 is a gear ring structure. The drive system 3 is transmission-connected with the transmission component 2-2, and is used to drive the drum 2 to rotate; the drive system 3 can be a motor that drives the gear to rotate, thereby driving the transmission component 2-2 to rotate.

[0063] The water cooling system 4 is used to spray cooling water onto the outer wall of the barrel 2-1; the spraying portion of the water cooling system 4 onto the barrel 2-1 extends from the feed end of the barrel 2-1 to the discharge end of the barrel 2-1 by a predetermined width; the predetermined width is preferably 1 / 3 to 1 / 2 of the length of the barrel 2-1.

[0064] A cold water spray system is added to the feeding end of the cylinder 2-1 to achieve the purpose of cooling; the air outlet of the fan system 5 is connected to the discharge end of the cylinder 2-1, and the air inlet of the fan system 5 is connected to the atmosphere; an air flow in the opposite direction of the movement of the proppant particles is generated to quickly take away the dust raised, and the air reaches the feeding port (kiln head) and becomes the secondary air of the front firing kiln for reuse. The fan system 5 is preferably a high-power fan connected to the cylinder 2-4 through a pipeline.

[0065] An embodiment of the present invention provides a single-tube in-situ turbidity reduction and cooling device for fracturing proppants, which can improve the cooling effect on proppant granular materials and reduce dust in the output proppant granular materials, thereby significantly reducing the turbidity index of the granular materials, reducing the subsequent processing costs of the granular materials, reducing the sintered blocks of the finished products, and improving the quality of the finished products.
