摘要
支撑剂作为非常规油气开采过程中的一种重要材料,在提高非常规油气采出率中起着至关重要的作用。随着支撑剂技术的发展,人们设计制备了一些多功能支撑剂来满足各种需求,而了解支撑剂在非常规油气开采过程中的作用机理及运移铺置规律也可以更有针对性的指导支撑剂的发展方向。本文介绍了支撑剂的分类、作用及现有技术,将支撑剂分为常见普通支撑剂和新型支撑剂后,综述了支撑剂运移铺置规律实验及模拟研究。目前,国内外支撑剂主要向着低密度高强度、高导流能力和多功能化方向发展,而结合支撑剂运移铺置实验数据来完善欧拉—欧拉、欧拉—拉格朗日以及拉格朗日—拉格朗日模型的模拟研究也是未来支撑剂运移规律探索的重要发展方向。
As an important material in the process of unconventional oil and gas production,proppant plays a vital role in improving the recovery rate of unconventional oil and gas.With the development of proppant technology,multifunctional proppants have been designed and prepared to meet various needs.Understanding the mechanism of proppant action and migration patterns during unconventional oil and gas production can also provide more targeted guidance for proppant development.This paper introduces the classification,functions and existing technologies of proppants.After dividing proppants into common proppants and new proppants,experimental and simulation studies on proppant migration and placement rules are reviewed.At present,proppants at home and abroad are mainly developing in the direction of low density,high strength,high conductivity and multi-functionality,and combined with the experimental data of proppant migration and placement to improve the simulation study of Euler-Euler,Euler-Lagrangian and Lagrangian-Lagrangian model is also an important development direction for the exploration of proppant migration rules in the future.
