基于3D打印技术的模拟油藏储层微流控仿真与实验研究
发布时间：2021-11-19 11:47
石油是不可再生资源,石油持续稳产增产涉及国家的能源安全。随着油田开发难度逐年增大,第三次采油技术即提高采收率（EOR）技术不断涌现。然而许多EOR技术难以大规模推广是由于其微观机理及微观采油效率尚不明确。传统胶结式人造岩心具有微观结构不可控,实验重复率低,流动过程无法观察等限制一直制约相关领域研究的发展。近年来,微流控技术的发展为EOR技术研究与评价提供了新平台。但传统微流控芯片制备工艺难以满足模拟储层多孔介质复杂结构成型要求。因此,本文基于面投影微立体光刻技术开展模拟储层多孔介质结构与微流控制相关研究。采用自主研制的微立体光刻打印系统开展模拟储层多孔介质微流场模块制备方法研究,研究了光敏树脂添加剂对增材制造工艺的影响规律。打印了三种用于实验研究的模拟储层多孔介质模块。分析了打印精度的影响因素,优化了微流控模块打印过程工艺流程与参数。流体在近井地层中的流动主要涉及多孔介质的渗流,开展了不同性质流体流入储层过程实验研究。分别进行了微流控模块亲水和疏水性实验所提出的方法可以在空间上描绘具有疏水/亲水区域的表面,该表面可作为微流控通道,并且该表面可应用于具有其他类型基底的微流控器件。利用CO...
