Description

Technical Field

[0001] The utility model relates to the technical field of fracturing and acidizing, in particular to an integrated agent composite adding device for fracturing and acidizing engineering. Background Art

[0002] Acid fracturing is referred to as acid fracturing. It is to use acid as fracturing fluid at a pressure higher than the formation fracture pressure, and to perform fracturing without adding proppant. During the acid fracturing process, the wall of the crack is corroded into an uneven surface by the dissolution of the acid, so that after stopping the pump and unloading the pressure, the wall of the crack will not be completely closed. Therefore, it has a higher conductivity and is effective in restoring and improving the production capacity of oil wells. This method is suitable for carbonate reservoirs.

[0003] During the manufacturing process of fracturing acidizing fluid, a mixing device is required to add various reagents. However, the existing mixing device cannot accurately add reagents during use, resulting in some errors in the amount of reagents added, which can easily affect the quality of the fracturing acidizing fluid.

[0004] The existing Chinese patent with announcement number CN216778526U discloses a continuous mixing device for fracturing acidizing liquid, including a mixing box, a liquid storage tank is provided on the top of the mixing box, a liquid discharge pipe with a valve is installed in the liquid storage tank, the liquid storage tank is provided with a sliding sleeve, a sliding rod is arranged in the sliding sleeve, the sliding rod is provided with an extrusion plate, the top of the extrusion plate is connected to the liquid storage tank through multiple telescopic rods and multiple springs, a mounting box is fixedly provided on the left side of the liquid storage tank, a slide plate is slidably connected to the inside of the mounting box, the mounting box is threadedly connected with bolts, a plurality of thread grooves are penetrated on the slide plate, the thread grooves are threadedly connected with the bolts, a limit plate is fixedly provided on the top of the slide plate, and a stirring mechanism is provided inside the mixing box, and its height can be accurately adjusted by means of a scale, a slide plate, a bolt, a thread groove and a limit plate, and then the extrusion plate is used to extrude a certain amount of medicine with the help of a spring, thereby realizing quantitative input and greatly reducing the generation of errors.

[0005] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the device uses a spring to make the extrusion plate squeeze out a certain amount of reagent, but the spring has a minimum contraction amplitude, which makes it impossible for the extrusion plate to rise to the top of the liquid storage tank, and thus the reagent cannot be completely squeezed out, which needs to be improved; therefore, an integrated reagent composite addition device for fracturing and acidizing engineering is proposed to address the above problems.
