摘要/Abstract

摘要： 预交联凝胶颗粒在多孔介质中的运移堵塞特征是影响其深部调剖性能的关键。目前，凝胶颗粒的力学性能如何影响其微观运移封堵特征尚缺乏深层次的认识。本文针对收集到的3种预交联凝胶颗粒，首次采用基于图像采集技术的弹性分析方法对凝胶颗粒弹性变形能力进行研究，并采用可视化填砂微观模型实验，重点分析了凝胶颗粒的力学性能对微观运移封堵的影响。结果表明，1#颗粒抗压强度大，韧性较强，不容易破碎，具有一定弹性变形能力，其对孔喉封堵能力强，但注入性较差；3#颗粒抗压强度适中，脆性较强，弹性变形能力弱，注入性好，但封堵能力较差；6#颗粒抗压强度较小，且弹性因子小，具有较好的封堵能力和注入性。预交联凝胶颗粒的弹性和抗压强度影响其在多孔介质中的注入性和封堵强度。该研究成果为预交联凝胶颗粒深部调剖性能评价及优选提供了理论指导和技术支撑。

Abstract: The migration and plugging characteristics of pre-crosslinked gel particles in porous media are the key factors affecting their deep profile control performance. At present,how the mechanical properties of gel particles affect their micro migration and plugging characteristics is not well understood. For the collected three kinds of pre-crosslinked gel particles,the elastic modulus analysis method based on image acquisition technology was used to study the elastic deformation ability of gel particles for the first time,and the influence of the mechanical properties of the gel particles on the micro migration and plugging was analyzed by the experiment of visual microscopic model filled with sands. The results show that No. 1 gel particle with high compressive strength and strong toughness is not easy to be broken. It has some elastic deformation ability,and its plugging capacity is strong and injection capacity is poor. No. 3 gel particle is characterized by moderate compressive strength,strong brittleness, poor elastic deformation ability,strong injection capacity and poor thus plugging capacity. No. 6 gel particle is characterized by poor compressive strength,small elastic factor,good plugging effect and injectability. This study can provide theoretical guidance and technical support for the evaluation of deep profile control performance and optimization of pre-crosslinked gel particles.
