The effect of the oil detergent on the main detergent is due to the existence of an oil film on the dirt, so that the detergent cannot directly contact the dirt, so that the detergent cannot exert its direct dissolving and chelating effect; Some organic ingredients are entrained in the production process, so adding a certain amount of detergent to the detergent will increase the speed and rate of scale dissolution. The influence of penetrant, dispersant and auxiliary agent on the main scale solvent penetrant, dispersant and additive auxiliary agent can stimulate the chelation reaction of ZYED. These additives can not only increase the permeability and dispersibility of scales, but also provide energy and a buffer protection.
Corrosion performance of the scale cleaning agent and the corrosion performance of the main scale cleaning agent as an accessory to the formation: According to the static exposure method in the SYJ26-87/water corrosion test method, the corrosion rate of the scale cleaning agent is 0.1257mm/ao. Compatibility of agent and formation: The main cleaning agent has good compatibility with formation water, bactericide and demulsifier. The mechanism of action of the anti-scaling agent The adsorption process on the surface of the anti-scaling agent molecule particles is always accompanied by the formation of sufficiently stable companion organisms. At this time, the anti-scaling agent inhibits the further growth of calcium carbonate, gypsum, calcium or slightly soluble salt germ crystals. The formed adsorption layer not only hinders the combination of crystals, but also adheres to the inner surface of the equipment and pipelines. The liquid stream carries tiny crystal grains to provide assurance.
Anti-scaling agent can increase its anti-scaling rate by compounding. The static adsorption capacity of the copolymer anti-scaling agent is large, the static adsorption capacity of the organic phosphate/ester anti-scaling agent is small, and the organophosphate/salt anti-scaling agent has a high anti-scaling rate, and the copolymer anti-scaling agent is anti-scaling The rate is relatively low. Flow adsorption has passed the preliminary screening of the anti-scaling rate of the anti-scaling agent, and the compounding effect and the static adsorption capacity of the anti-scaling agent have been evaluated. The formula of FG-A and GJ-5 anti-scaling agent as the compound anti-scaling agent is determined. .
