Polyacrylamide is a polymer compound, known as a “universal additive” and a “miracle product” due to its active acyl groups on its main chain and its water solubility. In the petroleum development process, polyacrylamide is widely used in oilfield operations…
The application of emulsifiers in oilfields spans key stages such as drilling, oil production, gathering and transportation, and storage. The emulsification requirements vary significantly across different scenarios, necessitating the selection of specific emulsifier types and formulations to achieve precise control.…
Demulsification refers to the complete breakdown of an emulsion, resulting in two immiscible phases. During oil extraction, changes in formation pressure, temperature, flow rate, and other factors can cause emulsions in crude oil to rupture, leading to the separation of…
Part 1: The Invisible Battleground — The Robust Armor of Emulsions and the Demulsifier’s Raid1.1 Order in Chaos: Thermodynamics and the Formation of Emulsions In the grand narrative of oil exploration and industrial processing, a minute yet stubborn physical phenomenon…
In the last part, we established the profound dialectical relationship between interfacial tension and the demulsification effect of the demulsifier: it is both the necessary driving force to break the oil-water interface and a key variable that needs to be…
4.1 The Scientific Workflow: From High-Throughput Screening to Kinetic Evaluation Based on interfacial tension testing, a complete R&D workflow from primary screening to fine-tuning optimization can be constructed. This is not merely a stack of testing steps, but a logically…
The extraction of unconventional oil and gas has become a crucial component of the global energy supply system, reshaping market landscapes and enabling the exploitation of previously uneconomical oil and gas resources. Unlike conventional resources found in permeable, porous sediments,…
introductionThe importance of water injection barium-strontium scale inhibitors in the oil and gas industry is increasing. With the deepening of oilfield production, the demand for water treatment is increasing, and scale inhibitors play a key role in keeping oilfield equipment…
Oilfield clay stabilizer is a special type of clay stabilizer used in the process of oilfield development and production. In oil field development, the soil or rock in the underground reservoir often needs to be treated to ensure the stability…
Abstract: This report aims to systematically study and investigate the application of sodium gluconate in the field of petrochemicals. Through literature review and on-site surveys, a comprehensive understanding of the properties, preparation processes, and potential applications of sodium gluconate in…
