Polyacrylamide (PAM) Used As Fracturing Fluid Additive

Fracturing is one of the main facilities for increasing oil and gas wells. Fracturing is the use of high-pressure pump fracturing fluid injected into the formation, the formation of cracks and the expansion of new cracks and fill proppant, thereby enhancing the permeability of the formation. After the fracturing process equipment is determined, the effect of fracturing is mainly determined by the fracturing fluid.

Early fracturing fluid is the gasoline as a dispersion medium, adding a certain viscosity of the fluid, which is the earliest oil-based fracturing fluid. This was first used in oilfield around 1948’. After that traditional water-based guar gum fracturing fluid was developed to adopt more complicated conditions like deeper well, a wide range of temperatures and higher viscosity request. While there are some disadvantages of Guar gum fracturing fluid, like high content of undissolved substance and residue, incompletely breaking. All these would easily cause formation damage and lead to the development of a new fracturing fluid.

In recent years, considering the economic and environmental reasons, a new type of fracturing fluid is developed to replace the guar gum system and is widely used. The synthetic polymer fracturing fluid, polyacrylamide (PAM), partially hydrolyzed polyacrylamide (HPAM), acrylamide-acrylamide copolymers, methylidene polyacrylamide were used. The performance of the polymer can be adjusted by controlling the synthesis conditions to meet the performance index of the fracturing fluid. The synthetic polymer fracturing fluid can meet the severe requirements of fracturing fluid temperature and viscosity and has very limit affection to the formation. Polyacrylamide (PAM) does not contain water-insoluble like the plant gum, and could be completely dissolved in water. The distribution of the fracturing liquid is crystal translucent and does not contain solid components. This kind of fracturing fluid can block the fracture and increase the gel strength. Its main advantages are the better price than guar gum and more environmental character.

Sinofloc emulsion polyacrylamide could be used as clean fracturing fluid additive and together with a number of biological enzymes like surfactants, and the break agent. To learn more information please contact us marketing@sinofloc.com.

Sinofloc Polyacrylamide Flocculants for Water Treatment

Treatment of natural water and sewage is closely linked to preservation of the environment and is thus an actual present day problem. During the last decades there have been noticed substantial increase of the content of heavy metals, mineral oil, poorly-oxidable organic compounds, synthetic surfactants, pesticides and other pollutants from insufficiently treated effluents of industrial and municipal enterprises in open water reservoirs. In spite of the great number of elaborations reported in literature, the problem of natural water and sewage treatment has not yet been solved. Hence, the technology of water treatment needs further perfection which mainly includes the ways of intensive use of reagents, in particular flocculants. For these purposes water-soluble high-molecular compounds among which the most widespread and universal are polyacrylamide flocculants are used. As a result of their application the efficiency of removal of heavy metals is increased by 95%, compounds of phos

Product Selection Of Sinofloc Polyacrylamide

Sinofloc has developed a wide range of polymers , both in dry powder and liquid emulsion forms, to cover the vast majority of existing conditions within the various industries (water treatment, mining processing, oil & gas etc.). Sinofloc polyacrylamides range from cationic to non-ionic and anionic in nature, and the selection of the best product depends on several parameters. General guidelines regarding typical product selection for a given application used in a specific industrial can be found on the individual product technical data sheets, as well as in the sections regarding the industries we serve. However these are not to be taken literally. In order to select the optimum product for a specific application, it is essential that laboratory testwork followed by plant trials are carried out. Initial laboratory testwork will give an indication of the best product and approximate dosage, which will then need to be confirmed with more accuracy by running plant trials

Sinofloc Polyacrylamide Used As Oil Field Additives

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 to carry c
