Enhancing oilfield development and production efficiency necessitates a synergistic approach that integrates fracturing and oil displacement techniques. Our research delves into the optimization of surfactants for this purpose, focusing on their interfacial tension reduction, emulsification properties, and salt tolerance. After rigorous screening, we identified 0.3% XPQ-5, a domestically produced surfactant, as the optimal choice due to its exceptional ability to withstand high mineralization levels while achieving an interfacial tension as low as 10−3 mN/m. Moreover, we evaluated the adsorption performance of quaternary ammonium salts, revealing that the utilization of DAA-64, another domestically developed product, significantly reduces their adsorption rate to just 2.5%. This reduction underscores DAA-64's potential to mitigate quaternary ammonium salt accumulation in reservoir strata. Building upon these findings, we formulated a novel fracturing-oil displacement integrated working fluid. This fluid is designed to bolster the stability and extension of rock fractures during fracturing operations, thereby enhancing the permeability and seepage capacity of oil and gas. Furthermore, the oil displacement component incorporated into the fluid promotes the mobilization and agglomeration of crude oil within the formation, ultimately augmenting production output. Our study underscores the significant benefits of employing this integrated working fluid. Not only does it elevate oilfield development efficiency, but it also contributes to cost savings in production processes. These advantages hold immense potential for boosting oilfield production and enhancing overall profitability.
