摘要
本文对磁铁矿原油基磁流体进行了合成和研究。测定了它们的理化参数(密度、粘度、磁相粒度)。进行了红外光谱和热重分析。磁致热的属性(磁性液体的磁热效应和热容)由微量热方法在278 - 350 K温度范围内的磁场改变其值从0到1.0 t磁热效应的最大值的磁性流体磁相体积浓度为0.08是0.0035在310 K和K磁感应获得的1.0 t .磁性液体样品因为原油生产成本较低油用作载液，可推荐用于石油和天然气工业的各种应用，例如压井。
Oil-based magnetic fluids. Synthesis, properties, and application prospects
In this work, magnetite crude oil-based magnetic fluids have been synthesized and studied. Their physicochemical parameters (density, viscosity, magnetic phase particle size) have been determined. IR spectroscopy and thermogravimetric analysis have been performed. The magnetocaloric properties (magnetocaloric effect and heat capacity) of magnetic fluids have been determined by the microcalorimetric method in the temperature range of 278-350 K in the magnetic field changing its value from 0 to 1.0 T. The maximum value of the magnetocaloric effect of a magnetic fluid with a magnetic phase volume concentration of 0.08 is 0.0035 K at 310 K and at the magnetic induction to 1.0 T. The obtained samples of magnetic fluids have low production costs because crude oil is used as the carrier fluid and can be recommended for various applications of the petroleum and gas industry, for example, for well killing.
