Sinofloc   polyacrylamide flocculants  has good performance in thickening, flocculation, and fluid rheology modifiers, which is widely used in drilling, plugging, water acidification, fracturing, wash well, completion, drag reduction, scale and drive oil . Currently many oil fields have entered the field of secondary, tertiary recovery, reservoir depth of 1000m above generally in some reservoir depth of 7000m, heterogeneity and offshore oilfield in oil production operations to the proposed more stringent conditions, deep oil and offshore oil corresponding to PAM also raised new demands to shear resistance, high temperature (above 100 ℃ up to 200 ℃), resistance to calcium ion, magnesium ion, seawater degradation. Our products show a good performance in Enhanced oil recovery (EOR). Partially hydrolyzed polyacrylamide (HPAM) is often used as drilling adjusting agent, which consists of polyacrylamide hydrolysis. Its role is to regulate the rheology of the drilling fluid t...

Polyacrylamide (PAM) is not only a high-performance flocculants, but also a very good thickener because of the high viscosity. Due to its thickening, flocculation and regulation of rheological properties, PAM could be used as a variety of additives, such as drilling fluids, fracturing fluids, and additives in  Enhanced Oil Recovery  (EOR) . The key point to get the best performance of polyacrylamide in specific application is optimal design and selection of the products in the molecular weight, ion degree way and together with the oilfields conditions. Polyacrylamide (PAM) could be used as a  drilling fluid additive .  The role of polyacrylamide is to adjust the rheology of the drilling fluid, carry cuttings, lubricate the drill bit and facilitate drilling. This application could also reduce the drill accident and relieves the equipment from wear, and prevents the occurrence of well leakage and collapse. Polyacrylamide (PAM) could be used as a polymer flooding...

The concept of drag reduction was first proprosed in the 1940s. In the early 20th century, firefighters in New York used water-soluble polymers to increase the flow of the drainage system. In 1948, a small amount of polymethyl methacrylate (PMMA) was dissolved in chlorobenzene, and the friction resistance could be reduced by about 50%. In the late 1960s, oil producers in the United States were able to use the drag reduction agent to transport and improve the delivery of crude oil pipelines across the Asga pipeline and it did a huge success. After that, the technology of drag reduction is further developed and widely used. In the 1980s, China also began to develop and test domestic anti-drag agents and carried out medium-sized tests on domestic crude oil pipelines. The performance of products had reached the level of foreign countries in the early 1970s. In recent years, the Petrochina Pipeline R&D Centerhas carried out the research work of drag reduction agent, and h...

Polymer is a substance that greatly increases the viscosity of the liquid which mixed with this polymer and water. Polymer flooding is mainly to use polymer to increase the viscosity of injected water, reduce the ratio of oil to water flow, and increase sweep efficiency. Firstly, from the rheology of the polymer, it can be seen that the viscosity of the water increases significantly after adding the polymer, and the higher concentration of the polymer, the stronger of the viscosity. In addition, when the rock surface is hydrophilic, the polymer is easily adsorbed on the surface. When the injected water passes through the surface of the adsorbent layer, the thin film of the adsorbent layer expands, thereby reducing the effective permeability of the aqueous phase. When the oil comes into contact with the adsorbent layer, no swelling will occur. Therefore, in oil layers with very low oil saturation, the use of polymers can significantly reduce the flow of water, increase the sweep efficie...
