Resistance Performance

An anionic surfactant clean fracturing fluid was synthesized and its main performance was studied. The viscosity of fracturing fluid increased with increasing dosage of anionic surfactant. And the viscosity of fracturing fluid increased first, and then decreased with increasing concentration of KCl. The viscosity reached maximum 360 mPa•s when the KCl content is 2.7%. The results showed that the fracturing fluid had best temperature resistance and shear resistance performance under the condition of 100°C and at the shearing rate of 170 s-1. The sedimentation velocity of sand in the fracturing fluid are about 11.124, 18.840 mm/min at the temperature of 80°C and 120°C respectively. It indicated that the fracturing fluid has a better sand-carrying performance. The viscosity of fracturing fluid decreased below 5 mPa•s during 70 minutes when the dosage of kerosene was 3%, and the surface tension of the breaker fluid is 26.10 mN/m while the interfacial tension is 0.73mN/m. The low surface tension can meet the requirements of operation. The damage rate to the core is 7.65% and the fracturing fluid has lower damage to core than guar gel.

AbstractThe production of surfactant from biological and renewable sources is important as this reduces environmental hazards since the products are highly biodegradable. Oil extracted from the seed of Luffa cylindrica using hexane in a soxhlet extractor was used in the synthesis of sodium phosphate-hydroxy ethanolamide via a simple reaction mechanism. The progress of the reaction was monitored and confirmed by FTIR, 1HNMR and 13CNMR. The process used gave a yield of 88.46% of sodium phosphate-hydroxy ethanolamide. The properties of this compound were compared with those of sodium dodecyl sulphate (SDS) used as a known reference surfactant. Important properties of sodium phosphate-hydroxy ethanolamide such as foam stability, wetting power and surface tension turned out superior to those of the known reference surfactant (SDS).

The effect of an divalent electrolyte Ca2+ on the flocculation of two different concentrations of anionic surfactant Sodium Dodecylbenzenesulfonate (SDBS) with Al3+ has been investigated at different molar ratios Al3+ to SDBS at 298.15 K. The results showed that the flocculation characteristics of 0.01 mol•L-1 SDBS (above the critical micelle concentration CMC) and 0.001 mol•L-1 SDBS (below the CMC) were obviously different with an increase of dosages of Al3+. The z-average size of flocculate of 0.01 mol•L-1 SDBS with Al3+ decreased particularly with the pre-addition of Ca2+，It suggested the formation of the complexion Ca(SDBS)2. At optimization flocculation areas at 298.15K, pH values were all around 3.5 in the flocculation systems SDBS/Al3+ and Ca2+/SDBS/Al3+ whether the SDBS concentration above or below the CMC. The pre-addition of Ca2+ slightly affected other flocculation parameters of SDBS/Al3+ systems such as zeta potential, surface tension, conductivity and pH.

Emulsifying Ability

The main role of this study is to prepare the green polymer based anionic surfactant as an alternative to non-biodegradable surfactant for detergent applications. The detergent properties i.e., surface tension measurements, foaming property, emulsifying ability, dispersing property, FTIR analysis and wetting behaviour were studied using several rheological techniques. The critical micelle concentration (CMC) value was obtained at 6 mg/L of surfactant concentration showing no further remarkable changes in surface tension with increases in concentration. Low surface tension value was correlated with decrease in cohesive force exist between the molecules and allowed the surfactant easily adsorbed on the pore surface. The low surface tension value, reliable wetting characteristic, excellent emulsifying power, benchmark dispersing behaviour and suitable foaming property assuring the successful utilization of polymer based anionic surfactant for detergent applications
