Application of Viscometer in Crude Oil Mining
A polymer is a high molecular weight compound that is linked by one or several structural units by covalent bonds. Also known as polymer compounds. The macromolecular chain is a combination of structural units and covalent bonds. Many macromolecular chains are aggregated into a polymer material through intermolecular interaction. Therefore, the polymer structure can be divided into a chain structure and an aggregate structure .
The composition of the interaction between the polymer and the polymer, the viscosity reducer is to break up part of the structure of these structures and to reduce viscosity. The performance of polymer drilling fluids is not perfect, and some problems are encountered in field applications. Further research and solutions are needed. The role of polymer drilling fluids in drilling operations and protection of oil and gas layers and the face of drilling fluids The strict requirements have led to rapid development of drilling fluid technology. After years of research and development and production practices, drilling fluids have evolved from drilling drills to drilling fluid systems that meet all needs. The polymer drilling fluid developed in recent years has been further improved in terms of inhibition and flow pattern adjustment, laying a solid foundation for future development. The development of polymer drilling fluid must be broad!
Water-soluble polymers are widely used in many industrial fields (such as mining, tertiary oil recovery, paint manufacturing, sewage treatment, industrial water, etc.). The aqueous solution of polyacrylamide has a very high viscosity and can form hydrogen bonds with many compounds. In practical applications, the polymer is used in combination with a surfactant to improve its efficiency. Therefore, research on water-soluble polymers and surfactants The interaction between the two has important theoretical and practical significance. Different types of polyacrylamide, hydrophobically modified polyacrylamide and cationic Gemini surfactant were synthesized, and the interaction between various polyacrylamide and cationic surfactants was studied. Hydrophobicity was also studied. The interaction between modified polyacrylamide and different types of surfactants. The experimental results show that the main driving force of the interaction between polymer and surfactant is hydrophobic interaction, and it is proved that the electrostatic interaction between water-soluble polymer and surfactant also has an important influence on the interaction between the two. . Gemini surfactants have superior properties over their corresponding general single-chain surfactants, such as better water solubility, wettability and foamability, lower critical micelle concentration (CMC) values, and more efficient Reduce the performance of the surface tension of the surface (boundary) and so on.
After decades of development in polymer oilfield application technology, a series of effective technologies for oil well drilling, water control and oil stabilization, and improvement of water flooding development have been formed to adapt to different reservoir conditions. After the polymer is injected into the oil layer, thermal degradation and further hydrolysis occur under high temperature conditions, which destroys the stability of the polymer and greatly reduces the oil displacement effect of the polymer. At the same time, the mineralization of the formation water and the injected water is favorable for the polymer to be thickened. Because of the high salinity of water, the viscosity of the polymer can be lowered, the amount of polymer injected can be increased, thereby increasing the cost, which is not conducive to the application of polymer flooding. Therefore, it is necessary to increase the intensity in the research of temperature resistance and salt resistance. The suitable additives are screened out so that the oil displacing agent not only has strong viscosity, but also has good stability.
In the tertiary mining of crude oil, the polymer is widely used in various links. The quality and characteristics of the polymer, especially under special shear conditions, directly affect the effect of driving into the oil well, and whether it can be better and more mined. The residual crude oil viscosity is an important indicator . Viscosity detection is especially important.

Brookfield viscometers are commonly used in the manufacturing industry to detect and control product viscosity. Brookfield Viscometers are accurate to ±1% of the measurement range and have a reproducibility of ±0.2%. The Brookfield Viscometer provides precise control of viscosity and is an indispensable tool for production and product development.
The Brookfield Viscometer is the world's first viscometer and invented the first rotary viscometer, the first to create a world standard for viscosity measurement. With 80 years of production experience, Brookfield's name is synonymous with precision in the field of viscosity measurement and control. Brookfield Viscometer has become the industry benchmark for viscometers with a market share of over 70%. The Brookfield Viscometer is stable, reliable, accurate and repeatable. It can be precisely controlled to the proper viscosity range after being measured by a precision Brookfield viscometer.
