Description

A production and processing equipment for solid drag reducing agent for fracturing

Technical Field

The invention belongs to the technical field of petrochemical industry and relates to a production and processing equipment of a solid drag reducer for fracturing.

Background Art

In oilfield production stimulation operations, fracturing fluid is pumped to a borehole at a depth of about 500 to 6,000 meters or even deeper under high pressure and high flow rate conditions to crack the rock formation around the wellbore. Drag reducers are agents that can reduce the resistance encountered by fluids during transportation. Most of them are water-soluble or oil-soluble polymers. With the development of oilfield cementing technology, the requirements for the performance of cement slurry used for cementing are getting higher and higher. Drag reducers in fracturing fluids reduce resistance during migration by increasing viscosity and reducing turbulence. Therefore, the quality of drag reducers directly affects the use effect of fracturing fluids.

Most existing drag reducers are liquid and cannot meet some specific usage requirements, while existing solid drag reducers have low production efficiency, especially poor energy recycling effect, which will result in high cost and high energy consumption.

After searching, it is found that a Chinese patent document discloses a solid drag reducer drying device for oil well cement [Publication No.: CN216790733U]. This solid drag reducer drying device for oil well cement includes a drying box, a drying box is slidably arranged in the drying box, a hot air blower is fixedly installed on one side of the drying box, the output end of the hot air blower extends into the drying box and is fixedly connected with a hose, a delivery pipe is fixedly connected to the hose, the delivery pipe is fixedly arranged in the drying box, an annular air duct is fixedly arranged in the drying box, the delivery pipe extends into the drying box and is fixedly connected with the annular air duct, and a plurality of air nozzles are fixedly connected to the annular air duct. Although the structural design is reasonable, the drag reducer can be fully turned over when the hot air is blown to dry the drag reducer, which improves the drying efficiency of the drag reducer and has a good drying effect. However, it is only suitable for small-batch production needs, and can only perform drying treatment, with poor functionality and inability to complete assembly line processing.

Therefore, we propose a solid drag reducer production and processing equipment for fracturing, which can realize raw material processing, loading, mixing, drying, crushing, and collection of assembly-line solid drag reducer processing operations, and reuse heat and water resources, which is energy-saving and environmentally friendly and has low cost.

The induced draft fan draws air and sucks the mixed material into the double-rotor crusher under negative pressure for crushing to obtain finished materials with the required particle size.

Working principle of the present invention:

Solid raw materials are introduced into the raw material crusher for crushing to form powder. The induced draft fan 2 uses negative pressure suction to suck the powder into the raw material settler and quantitatively send it into the mixing and stirring tank. The raw material fine powder is collected into the raw material bag collector through the induced draft fan 2 and can be reused to avoid dust splashing. Alternatively, the solid raw material (powder) is directly sent to the fourth floor from the loading elevator and quantitatively poured into the mixing and stirring tank. The liquid raw material is pumped into the liquid mixing tank, and the liquid mixture obtained after stirring is injected into the mixing and stirring tank for mixing. After the mixing is completed, the mixed liquid material is injected into the rake dryer, and the rake dryer cooperates with the three-stage condenser to perform rake drying.

The hot steam generated by the rake dryer and the exhaust fan enters the interior of the tubular condensation body 16 on the upper side through the steam inlet main pipe 17, and then enters the interior of the tubular condensation body 16 on the lower side through two connecting pipes 15, undergoes a condensation treatment once, and obtains condensed water. The condensed water enters the hot steam filter box through the outlet pipe 13, and the excess hot steam enters the plate condensation body 18 through the water inlet pipe 12 through the exhaust pipe 14 symmetrical on both sides, and undergoes a secondary condensation treatment through a number of wind condensation plates 19 to obtain condensed water. The condensed water enters the hot steam filter box through the exhaust pipe 3 10, and the excess hot steam enters the spiral condensation body through the exhaust pipe 2 11 and the water inlet pipe 2 8, and undergoes a third condensation treatment to obtain condensed water. The condensed water is discharged into the water collecting box 4 through the outlet pipe 2, and the excess hot steam is discharged into the hot steam filter box through the exhaust pipe 4 9 and the exhaust pipe 5 22. The sewage pipe 20 is used for sewage discharge when cleaning the tubular condensation component 1, the two plate condensation components 2 and the two spiral condensation components 3;

The condensed water is discharged into the water collecting tank 4 through the water outlet pipe 2 via the water inlet joint 3 21, and the water storage pump group 5 is used to inject the water in the water collecting tank 4 into the hot steam filter water tank through the water outlet pipe 3 6; the condensed water and hot air are obtained, and the hot air is introduced into the drying conveyor 24 for drying;

The output shaft of the conveying motor 40 drives one of the rotating shafts of the conveying crawler 36 to rotate, thereby driving the conveying crawler 36 to convey the material. The mixed slag material dried by the rake dryer is poured into the collecting box 35. The conveying crawler 36 conveys the mixed slag material and falls on the diverter roller 37. One of the rotating shafts of the conveying crawler 36 drives the diverter roller 37 to rotate through the transmission sprocket pair 38, which is used to flatten the mixed slag material, ensuring that the mixed slag material falls evenly on the air hole conveying chain 32 and enters the heat preservation drying box 31. The hot air enters the heat preservation drying box 31 through a plurality of air inlet pipes 26, the hot oil of the heat conduction oil furnace enters the oil guide pipe 29, and then enters the heat preservation drying box 31 through the oil guide branch pipe. The oil guide valve 30 is used to control the hot oil flow rate and control the temperature. The exhaust fan 28 is used to blow air to dissipate heat, speed up the air flow rate, and dry the mixed slag material on the air hole conveying chain 32. The exhaust fan exhausts air under negative pressure, and the hot steam generated by drying is extracted through a plurality of induced draft hoods 27, or is directly discharged into the air, or is discharged into the interior of the three-stage condenser;

The dried mixed material enters the collecting hopper 42 and falls into the inside of the discharging spiral tube 43. The output shaft of the discharging motor 46 drives the discharging spiral tube 43 to rotate, and the mixed material is transported to the diversion tee 44. The induced draft fan draws air and sucks the mixed material into the double-rotor crusher under negative pressure for crushing to obtain finished materials with the particle size. The induced draft fan sucks the powdered solid drag reducer finished product into the finished product decompressor for collection and processing. The finer finished fine materials are sucked into the tail material bag through the induced draft fan for collection and processing.

The heat-conducting oil furnace provides heat for the liquid mixing tank, the raw material settler, the mixing and stirring tank, the rake dryer and the drying conveyor 24 for heat preservation or drying.

In summary, the raw material crusher cooperates with the raw material settler and the induced draft fan combined with the raw material bag collector to achieve the crushing, lifting and collection of solid raw materials. The solid raw materials can be transported through the loading elevator and the liquid raw materials can be injected through the liquid mixing tank.

The mixed material is raked and dried by the cooperation of the rake dryer, the conveyor crawler 23 and the drying conveyor 24;

The dried finished mixed materials are crushed and collected by the cooperation of the double-rotor crusher, finished product settler, induced draft fan and tailing bag collector, so as to facilitate the discharge of finished products.

Through the cooperation of the rake dryer and the three-stage condenser, the hot steam is quickly extracted for drying, and condensed water and hot air are obtained, and through the cooperation of the three-stage condensation and the drying conveyor 24, hot air is injected to fully utilize energy and reduce costs;

The heat transfer oil furnace cooperates with the liquid mixing tank, the raw material settler, the mixing and stirring tank, the rake dryer and the drying conveyor 24 to heat or dry the raw materials, the intermediate mixture and the finished mixture.
