The effect of the oil wash on the main scale remover is due to the existence of a layer of oil film on the scale, which prevents the scale remover from direct contact with the scale. This prevents the scale remover from exerting its direct dissolution and coexistence; During the production process, some organic components are entrained. Therefore, the addition of a certain amount of detergent in the scale-cleaning agent will increase the rate of scaling and the rate of fouling. Effects of penetrants, dispersants, and adjuvants on primary scales penetrants, dispersants, and additives can excite the ZYED deuteration reaction. These additives can increase their permeability and dispersibility of the scale, while also providing energy and a buffering protection.
Corrosion performance of scale-cleaning agent and corrosion resistance of the main scale-cleaning agent to the formations: Corrosion rate of the scale-removing agent was measured according to the static exposure method in the SYJ26-87/water corrosion test method 0.1257mm/ao Compatibility of the agent with the formation: The main scale remover has good compatibility with formation water, bactericide, and demulsifier. Anti-scaling agent mechanism of action Anti-fouling agent The adsorption process on the surface of the molecular particle is always accompanied by the formation of a sufficiently stable companion. At this time, the anti-scaling agent inhibits the further growth of calcium carbonate, gypsum, calcium, or the slightly soluble salt germ crystals, and the formed adsorption layer not only hinders the crystal's binding, but also adheres to the inner surfaces of the equipment and the pipeline. The liquid flow carries tiny crystal grains to provide assurance.
Anti-fouling agent can improve its anti-scaling rate by compounding. The anti-scaling agent of the copolymer has a large static adsorption capacity, the organic phosphate/ester type anti-scaling agent has a small static adsorption, and the organic phosphate/salt anti-scaling agent has a high anti-scaling rate, and the copolymer anti-scaling agent has an anti-scaling effect. The rate is relatively low. The flow adsorption was evaluated through the preliminary screening of the anti-scaling agent's anti-fouling rate, the evaluation of the compounding effect and the static adsorption capacity of the anti-scaling agent, and the formulation of FG-A and GJ-5 anti-scaling agent compounded as a compound anti-scaling agent was determined. .
