The following are some methods to reduce the usage cost of polyamine:

1. Optimize the production link and improve the production process of polyamine liquid 1) Reduce cost of polyamine by developing more efficient synthesis technologies, increasing the reaction yield and reducing the formation of by-products. For example, adopt new catalysts or optimize reaction conditions to reduce energy consumption and raw material waste. 2) Optimize the process flow, simplify the production steps and improve the production efficiency. Reduce the production cost of polyamine by reducing equipment investment and operation costs. 3) Look for cheaper raw materials to replace some expensive ones, but ensure that the performance of polyamine liquid is not affected. For example, through market research and technical analysis, select raw material suppliers with higher cost performance. 4) Establish a stable raw material supply channel, sign long-term cooperation agreements with suppliers and strive for more favorable prices and supply conditions. At the same time, strengthen the quality control of raw materials to avoid production losses caused by raw material quality problems. 2. Improve the usage efficiency polyamine solution for crude oil. 1) Through experiments and field tests, determine the optimal usage dose of polyamine in different polyamine oilfield application scenarios. Avoid waste caused by excessive use and ensure the expected effect at the same time. 2) Adopt advanced detection technologies and equipment to monitor the concentration and performance of polyamine in real time, so as to adjust the usage dose in time. For example, use online analytical instruments to monitor the polyamine content in oilfield water to achieve precise dosing. 3) Use in synergy with other chemical agents Study the synergistic effect of polyamine liquid and other oilfield chemical agents and develop compound formulations. Through the reasonable combination of different chemical agents, the usage amount of polyamine liquid can be reduced and the overall treatment effect can be improved. For example, combine polyamine with anti-swelling agents, flocculants, etc. give full play to their respective advantages and reduce the dosage of single chemical agents. 4) Optimize the application process of polyamine solution for crude oil treatment. Optimize the application process of polyamine liquid according to the specific conditions of the oilfield. For example, improve the injection method, adjust the treatment time, etc. to improve the utilization rate and effect of polyamine. For drilling operations, the method of staged injection of polyamine can be adopted and the dose can be adjusted according to the needs of different well sections to reduce the overall cost. 3. Management and maintenance aspects about polyamine liquid. 1) Equipment maintenance and management, regularly maintain and maintain the equipment using polyamine to ensure the normal operation of the equipment. Reduce equipment failure and maintenance costs and improve the service life of the equipment. Optimize equipment selection, select efficient equipment suitable for the application of polyamine liquid and reduce energy consumption and operation costs. For example, select energy-saving mixing equipment, delivery pumps, etc. 2) Personnel training and management Strengthen the training of operators, improve their operation skills and understanding of the performance of polyamine liquid. Ensure the correct use of polyamine and avoid waste and losses caused by improper operation. 3) Establish a scientific management system, standardize the links such as the purchase, storage, use and waste disposal of polyamines. Improve management efficiency and reduce management costs. 4) Establish an effective waste disposal system to properly handle the waste of used polyamine liquid. Reduce the pollution risk to the environment and reduce the treatment cost at the same time. 5) Explore the recycling methods of polyamine waste, for example, through chemical treatment or regeneration technology, convert the waste into reusable resources to reduce costs.
