Technical Field
[0001] The utility model relates to the technical field of fracturing fluid filling devices, and particularly relates to a fracturing fluid filling device for oil fields on site. Background Technique
[0002] Fracturing fluid is a chemical fluid with a specific formula, which is used for the fracturing operation of oil and gas wells to increase the fractures of rocks and improve the exploitation efficiency of resources. The main function of fracturing fluid is to transfer the high pressure formed by surface pumping equipment to underground rock formations during the fracturing process of oil and gas wells, causing the rock formations to break and form fractures, and conveying proppants (such as quartz sand, ceramsite, etc.) in these fractures to keep the fractures open, thereby increasing the fluidity and production of oil and gas.
[0003] When injecting fracturing fluid into the interior of an oil and gas well by a machine, it is often necessary to continuously inject fracturing fluid into the machine. In this way, when the fracturing fluid in a storage tank is used up, it is necessary to disconnect the connecting pipe and replace the storage tank. This method is rather troublesome and will also affect the continuity of injecting fracturing fluid into the oil and gas well. Therefore, a new type of fracturing fluid filling device for oil fields on site is needed to solve the above problems. Content of the Utility Model

Detailed Embodiments
[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
[0019] This application provides a fracturing fluid filling device for oilfield sites, mainly used to solve the problem that when injecting fracturing fluid into the interior of an oil and gas well by a machine, it is often necessary to continuously inject fracturing fluid into the interior of the machine. In this way, it is necessary to continuously inject fracturing fluid into the interior of the machine. After using up the fracturing fluid in a storage tank in this way, it is necessary to disconnect the connecting pipe and replace the storage tank. This method is rather troublesome and will also affect the continuity of injecting fracturing fluid into the oil and gas well, and provides the following technical solutions. The following will be combined with Figures 1-4 for a detailed description:
[0020] A fracturing fluid filling device for oilfield sites, comprising: a mobile rack 1 with a storage tank 2 arranged above it. The top of the storage tank 2 is fixedly penetrated by an external threaded pipe 3 and two liquid suction pumps 4. Both ends of the two liquid suction pumps 4 are fixedly connected to corrugated pipes 5. The orientations of the two liquid suction pumps 4 are opposite. Therefore, the user can achieve liquid discharging and liquid adding to the storage tank 2 through the two liquid suction pumps 4. At the same time, one end of each of the two corrugated pipes 5 is rotatably installed with an internal threaded pipe 6. The main components of the mobile rack 1 are: a main board 101 fixedly installed with a number of universal wheels 103 at the bottom. The user can move the main board 101 through a push plate 102 fixedly installed on the surface of the main board 101. At the same time, a notch 104 is formed on the surface of the main board 101, and a lifting plate 105 is arranged below the notch 104. It further includes a lifting mechanism 7 for installing the lifting plate 105 on the surface of the main board 101 and controlling the spatial height of the lifting plate 105. The main components of the storage tank 2 are: a tank body 201. A cover plate 202 is slidably inserted into the top of the tank body 201. The external threaded pipe 3 and the two liquid suction pumps 4 are fixedly penetrated through the surface of the cover plate 202.
[0021] During use, after the user places the storage tank 2 on the surface of the mobile rack 1, the user can move the storage tank 2 through the mobile rack 1. Then, connect one of the internal threaded pipes 6 to the liquid inlet of the machine to perform the refueling operation. During the refueling process, the user can thread one external threaded pipe 3 of another storage tank 2 onto the surface of the external threaded pipe 3 of this storage tank 2, so as to achieve continuous liquid supply to the interior of this storage tank 2, thus avoiding the replacement of the storage tank 2 during the liquid injection process, fully reflecting the practicality of the device.
[0022] As Figure 2As shown, in some embodiments, to further optimize the solution, the lifting mechanism 7 includes an empty tube 702 and an electric push rod 703. At the same time, a mounting plate 701 is fixedly installed on the surface of the main board 101, and both the electric push rod 703 and the empty tube 702 are fixedly penetrated through the surface of the mounting plate 701. One end of the empty tube 702 is slidably inserted with an insertion tube 704, and one ends of the electric push rod 703 and the insertion tube 704 are both fixedly installed on the surface of the lifting plate 105. Therefore, when the user controls the telescopic movement of the electric push rod 703, the lifting plate 105 can be driven to lift. During this process, the insertion tube 704 slides on the inner wall of the empty tube 702, ensuring the stability of the lifting plate 105 during the lifting process.
[0023] As Figure 3 shown, in some embodiments, to further optimize the solution, two handles 8 with rubber sleeves 9 fixedly sleeved on their surfaces are fixedly installed on the surface of the cover plate 202, and the user can move the cover plate 202 through the two handles 8.
