Description

Technical Field

[0001] This utility model belongs to the field of self-directing acid preparation technology, and particularly relates to an on-site preparation device for self-directing acids. Background Technology

[0002] Self-directing acid is a type of acid that occurs when surfactant molecules react with Ca during an acid-rock reaction. 2+ The self-directing acid forms columnar or rod-shaped micelles, exhibiting staged thickening properties. It temporarily blocks and redirects large pores and high-permeability zones, allowing fresh acid to continue penetrating deeper and redirecting to other low-permeability layers, thus increasing the effective reach of the acid. Once the acid reaches the target layer, the high-viscosity gel comes into contact with oil, gas, or formation water, disrupting the viscosities and completely breaking down the system. This facilitates the removal of the fluid from the formation. The main components of self-directing acid include acid, a deflecting agent for cleaning and redirecting the acid, acidizing corrosion inhibitors, iron ion stabilizers, and drainage aids. This combination of components enables self-directing acid to function under various geological conditions, forming micelles through the action of surfactant molecules to achieve temporary blocking and redirection of high-permeability zones.

[0003] Application No. 202323553311.4 discloses an acid mixing device, comprising: a mixing tank with a mounting base on its top; and a mounting block disposed on the inner wall of the mounting base. This mixing device utilizes a fixing assembly with components such as clips and slots to secure the mounting block, thereby enabling the installation of the mixing device. Compared to existing devices, the installation method is simpler, requiring only one person to complete the installation. The mixing device incorporates a rubber pad to buffer the connection between the mounting base and the mounting block, mitigating impact on the inner wall of the mounting base during installation as the mounting block moves downwards. For disassembly, pulling the lever inserts one end of a fixing rod into a limiting groove. Even when the lever is released, the fixing rod will not retract into the groove, allowing for the installation of the mounting block.

[0004] The existing technology still has the following shortcomings:

[0005] Existing mixing devices have limited mixing range when in use. They typically mix chemical products by rotating a stirring rod, resulting in low mixing efficiency between raw materials in the inner edge of the device, which affects the mixing speed of the chemical products.
