The polymer presents good friction reduction property under low concentration (≤0.15%) and prominent proppant-carrying capacity under high concentration (≥0.3%), which enables one polymer to be used for both slick water and gel fracturing fluid by changing its concentration in solution, obtaining the new multifunctional fracturing fluid system .
Compare with Guar Gum Gelling fluids and HPAM Friction Reduction Slick Water Fluids: At least 20-25% cost saving.
The Associative Polymer GRF-1H products have the great properties as followsing:
1.Fast Hydration: Under 20 C degree and Normal salinity water condition, the Powder GRF-1H polymer hydrated 100% in about 60 seconds;
2.One Polymer for both Gelling Fluids and Friciton Reducer Slick Water fluids ；
3.Great Friction Reduction Rate: With 0.05% GRF-1H,after 50-60 seconds, the FR could reach 80%
4.Multistage Viscosity Control:The multifunctional fracturing fluid system is non-crosslinked fracturing fluid which can adjust the viscosity freely by changing the polymer dosage.During fracture network and SRV, complex fracture network can be formed by optimizing the flow rate and viscosity.
5.Good shear resistance: The non-crosslinked gel fracturing fluid has strong shear resistance. Under stable temperature, the viscosity almost keeps stable under shear, presenting good shear resistance. This can meet the operation requirement of high flow rate SRV.
6. Prominent proppant carrying capacity: The non-crosslinked gel fracturing fluid has good proppant carrying capacity. Its dynamic proppant carrying time is larger than 120min, which ensures the successful operation.
7. Great Salinity Resistance:For salinity 0～250000mg/L, friction reduction rate can be kept at about 80% with 0.05%～0.075% polymer concentration for GRF-1H Series . And the friction reduction rate can reach 70% within less than 1 min. Products presents good solubility, salt resistance and efficient friction reduction properties.
