Description

Technical Field

[0001] This utility model relates to the field of petroleum engineering technology, specifically to a sand-adding device for oil and gas well fracturing operations. Background Technology

[0002] Petroleum engineering is a general term for a series of engineering technologies and scientific activities involving the exploration, development, production, transportation and processing of oil and natural gas. Oil and gas well fracturing sand filling equipment is a type of equipment specifically used for fracturing operations during natural gas extraction. Sand filling is an important part of the fracturing process. Its purpose is to fill the formed fractures with sand to keep the fractures open after the fracturing fluid pressure is released, thereby improving the fluidity and production of oil and gas.

[0003] A search revealed, for example, a Chinese utility model patent publication number CN221607197U, which discloses a continuous sand-adding device for fracturing operations. This device incorporates a uniform sand-adding feeding component, in which a sand-adding storage bin stores the materials required for sand addition. This ensures more uniform material delivery onto the conveyor belt, preventing blockages or uneven material distribution at the bottom discharge pipe. This facilitates continuous sand-adding during fracturing operations. However, while the feeding auger prevents uneven material distribution due to moisture inside the sand and gravel, its capacity to handle moist sand and gravel is limited. Moist sand and gravel may still clump together, clogging the feeding auger and affecting material delivery. Therefore, this paper proposes a sand-adding device for oil and gas well fracturing operations to address these issues. Utility Model Content

[0004] In the prior art, although measures have been taken to reduce the problem of uneven feeding caused by damp sand and gravel, the clumping of damp sand and gravel may still cause blockage of the feeding auger, thereby affecting the normal transportation of materials. This utility model provides a sand feeding device for oil and gas well fracturing construction that can reduce the impact of damp sand and gravel on sand feeding efficiency and thus reduce the risk of blockage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand-adding device for fracturing oil and gas wells, comprising a base plate and a fixed chamber, characterized in that: an installation plate is fixedly installed near the top inside the fixed chamber, a feeding cylinder is fixedly installed at the bottom of the installation plate, a first motor is fixedly installed inside the feeding cylinder, a feeding auger is fixedly installed at the output end of the first motor, a feeding conveyor belt is fixedly installed at the top of the base plate, a sand-adding storage chamber is fixedly installed inside the fixed chamber, and functional components are provided inside the sand-adding storage chamber;

[0006] The functional components include a second motor, which is fixedly installed on the surface of the fixed chamber. A stirring rod is fixedly installed at the output end of the second motor. Several stirring blades are installed on the surface of the stirring rod. A functional box is fixedly installed on the rear surface of the fixed chamber. A fan and a heating tube are fixedly installed inside the functional box. A temperature sensor is fixedly installed on the surface of the fixed chamber.

[0007] Furthermore, four columns are fixedly installed on the top of the base plate, a fixed compartment is fixedly installed between the four columns, a horizontal plate is fixedly installed between every two columns, and a purification component is provided on the top of the horizontal plate.

[0008] Furthermore, a discharge pipe is fixedly installed at the bottom of the sand storage bin, and the discharge cylinder extends into the interior of the discharge pipe, with the discharge pipe located below the fixed bin.

[0009] Furthermore, the bottom of the feeding cylinder has an opening, and the top front and rear sides of the feeding conveyor belt are fixedly installed with partitions, and the feeding pipe is located between the two partitions.

[0010] Furthermore, a feeding plate is fixedly installed between the inner wall of the sand storage bin and the outer surface of the feeding cylinder. A discharge pipe is fixedly installed at the bottom of the feeding plate. A solenoid valve is provided on the surface of the discharge pipe. Both the left and right side walls of the feeding cylinder are provided with material inlets. Both the fixed bin and the feeding storage bin are provided with openings at their rear sides. A filter screen is provided inside one of the openings. The temperature sensor's temperature probe extends through the inner walls of the fixed bin and the sand storage bin into the interior of the sand storage bin.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This sand-adding device for oil and gas well fracturing, through the combination of functional components such as a fan and heating pipes, blows heat from the heating pipes through openings into the sand-adding storage chamber, thereby drying the damp sand. A temperature sensor monitors the temperature inside the sand-adding storage chamber in real time. A second motor and a stirring rod, with stirring blades on the stirring rod, uniformly stir the sand, ensuring sufficient contact between heat and sand, thus improving drying efficiency. Continuous stirring prevents the sand from clumping or settling during the drying process, maintaining the sand's fluidity and uniformity, thereby reducing the impact of damp sand on sand-adding efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4The sand-adding device for fracturing oil and gas wells in this embodiment includes a base plate 1 and a fixed chamber 3. An installation plate 4 is fixedly installed inside the fixed chamber 3 near the top. A feeding cylinder 5 is fixedly installed at the bottom of the installation plate 4. A first motor 6 is fixedly installed inside the feeding cylinder 5. A feeding auger 7 is fixedly installed at the output end of the first motor 6. A feeding conveyor belt 8 is fixedly installed at the top of the base plate 1. A sand-adding storage chamber 9 is fixedly installed inside the fixed chamber 3. A functional component 11 is installed inside the sand-adding storage chamber 9.

[0021] The functional component 11 includes a second motor 111, which is fixedly installed on the surface of the fixed chamber 3. A stirring rod 112 is fixedly installed at the output end of the second motor 111. A number of stirring blades 113 are installed on the surface of the stirring rod 112. A functional box 114 is fixedly installed on the rear surface of the fixed chamber 3. A fan 115 and a heating tube 116 are fixedly installed inside the functional box 114. A temperature sensor 117 is fixedly installed on the surface of the fixed chamber 3.

[0022] like Figure 1 As shown, the fixed chamber 3 can be fixed by setting the column 2, and the purification component 12 can be supported by setting the horizontal plate between the columns 2.

[0023] like Figure 1 As shown, by setting up a feeding pipe 10, a first motor 6, a feeding auger 7 and a through-hole, the first motor 6 is started, which drives the feeding auger 7 to rotate and feed sand. The sand falls into the inside of the feeding pipe 10 through the through-hole of the feeding cylinder 5, and then falls onto the feeding conveyor belt 8 for conveying.

[0024] like Figure 1 As shown, by installing baffles on the top of the feeding conveyor belt 8 and placing the discharge pipe 10 between the two baffles, the sand and gravel are guided, ensuring that the sand and gravel can fall onto the feeding conveyor belt 8 and will not fall to the outside of the feeding conveyor belt 8, thus affecting the conveying of the sand and gravel.

[0025] like Figure 2 As shown, by setting up a feeding plate, discharge pipe, solenoid valve and feed port, when in use, by opening the solenoid valve, the sand and gravel on the top of the feeding plate can be guided to the bottom of the feeding plate through the discharge pipe, and enter the interior of the feeding cylinder 5 through the feed port opened in the cylinder wall of the feeding cylinder 5, and then conveyed by the feeding auger 7.

[0026] like Figure 2As shown, by setting an opening and a filter, hot airflow formed by the cooperation of fan 115 and heating tube 116 is blown into the sand storage chamber 9 through the opening. By setting a filter, sand and gravel inside the sand storage chamber 9 can be prevented from entering the functional box 114. Furthermore, by setting a temperature sensor 117 and a controller, the temperature probe of the temperature sensor 117 can extend into the sand storage chamber 9. The temperature probe of the temperature sensor 117 can obtain accurate temperature data of the sand and gravel in real time. Based on the obtained temperature data, the controller can adjust the working state of the heating tube 116 to maintain the sand and gravel within a suitable temperature range, prevent overheating or overcooling, and optimize the drying process. The controller, temperature sensor 117, and heating tube 116 are connected by electrical signals.

[0027] like Figure 1 and Figure 4 As shown, by setting up a purification component 12, which includes a purification box 121, a purification fan 122, a filter cartridge 123, and a dust suction pipe 124, the filter cartridge 123 is equipped with a filter screen and a filter element. The filter element is an electrostatic cotton filter element. After the device is used up, the purification fan 122 can be turned on. The purification fan 122 sucks the dust in the air into the filter box through the dust suction pipe 124. Large dust particles are filtered by the filter screen, and small dust particles are adsorbed by the filter element. The purified air is then discharged through the air duct. This setup can purify and filter the dust in the air, which is beneficial to environmental protection.

[0028] When implementing this procedure, please follow these steps:

[0029] 1) First, the heat from the heating tube 116 is blown into the sand storage chamber 9 through the opening by the fan 115, thereby drying the wet sand;

[0030] 2) Then, the temperature sensor 117 is set to monitor the temperature inside the sand storage chamber 9, and the working status of the heating tube 116 is adjusted by the controller.

[0031] 3) Then, by starting the second motor 111, the stirring rod 112 and the stirring plate 113 are driven to stir, thereby preventing the sand from clumping and settling during the drying process.

[0032] In summary, this sand-addition device for oil and gas well fracturing, through the setting of functional components 11, and the cooperation of a fan 115 and a heating pipe 116, etc., blows the heat from the heating pipe 116 into the sand-addition storage chamber 9 through the opening via the fan 115, thereby drying the damp sand. The temperature sensor 117 is set to monitor the temperature inside the sand-addition storage chamber 9 in real time. Furthermore, through the setting of a second motor 111 and a stirring rod 112, the stirring blades 113 on the stirring rod 112 uniformly stir the sand, ensuring that the heat is in full contact with the sand, thereby improving the drying efficiency. Through continuous stirring, the sand is prevented from clumping or settling during the drying process, maintaining the fluidity and uniformity of the sand, thereby reducing the impact of damp sand on the sand-addition efficiency.
