Polyacrylamide Used in Fracturing 2

The fracturing technology is an important stimulation measure for the development of compact layers in the oil field. It opens the channels of the rocks and allow the oil to flow through. The fracturing fluid cross-linked by polyacrylamide is widely used because of its advantages of high viscosity, low frictional resistance, good sand-suspending ability, convenient preparation and low cost.

The hydraulic fracturing process in the oil layer is based on a high-pressure, large-displacement pump on the ground. With the principle of liquid pressure transfer, a liquid with a certain viscosity (commonly referred to as fracturing fluid) is injected to the oil layer at a pressure larger than that of the oil layer. The pump also increase the pressure from the bottom of the wellbore. When this pressure is higher than the crustal stress near the borehole wall and the tensile strength of the formation rock, cracks will occur near the bottom of the wellbore. With the continuously injection of sand-carrying fluid, the crack extends forward and is filled with proppant. After the well is shut, the fracture is closed on the proppant, thereby forming a sand-filled crack with a certain geometric size and high conductivity in the stratum near the bottom of the well. It is the purpose of the oil well to increase production and increase injection. The proppant is also called fracturing fluid.

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
