Slickwater fracturing fluids are widely used in the development of unconventional oil and gas resources due to advantages low cost, formation damage high drag reduction performance. However, their performance is severely affected at temperatures. Drag reducing agent key determine slickwater. In this work, order further improve temperature resistance slickwater, a temperature-resistant polymeric (PDRA) was synthesized as basis for preparing The slickwater system prepared with compositions 0.2 wt% PDRA, 0.05 drainage aid nonylphenol polyoxyethylene ether phosphate (NPEP) 0.5 anti-expansion polyepichlorohydrin-dimethylamine (PDM). ability, rheology properties, shear core property were systematically studied evaluated. contrast on-site (DRA) HPAM, demonstrates enhanced efficacy 90 °C, exhibiting superior ability. Notably, retention rate achieved an impressive 90.52% after 30-min shearing period. Additionally, only 5.53%. We expect that study can broaden application high-temperature reservoirs provide theoretical field applications.
