Abstract

Bentonite, a smectite clay mineral, is essential in petroleum operations for its swelling capacity, thixotropy, and cation exchange properties. However, its effectiveness in high-salinity and high-temperature environments remains a significant challenge. This review synthesizes advanced engineering strategies to enhance bentonite’s performance for modern petroleum applications. It examines activation methods, including acid, thermal, alkaline, and nanomaterial treatments, and their effects on colloidal stability and rheological properties. The review highlights bentonite’s role in enhanced oil recovery, showing that polymer-clay nanocomposites improve thermal stability and conformance control. Data indicate that adding bentonite can extend polyacrylamide gel lifespan from 37 to 120 days at 100 °C and increase elastic modulus by 40 %. The review also evaluates Iranian bentonite reserves as a case study, analyzing their mineralogy and activation needs. By linking fundamental properties with targeted engineering, this review offers a strategic framework for developing advanced bentonite technologies to support more sustainable and efficient hydrocarbon recovery.

膨润土及其在石油工业中的应用综述

膨润土是一种蒙脱石粘土矿物，由于其膨胀能力、触变性和阳离子交换性能，在石油生产中至关重要。然而，它在高盐度和高温环境中的有效性仍然是一个重大挑战。本文综述了提高膨润土在现代石油应用中的性能的先进工程策略。它考察了活化方法，包括酸、热、碱和纳米材料处理，以及它们对胶体稳定性和流变性能的影响。该综述强调了膨润土在提高采收率方面的作用，表明聚合物-粘土纳米复合材料改善了热稳定性和一致性控制。数据表明，添加膨润土可使聚丙烯酰胺凝胶在100℃下的使用寿命从37天延长至120天，弹性模量提高40%。该报告还评估了伊朗膨润土储量作为案例研究，分析了其矿物学和活化需求。通过将基本特性与有针对性的工程相结合，本综述为开发先进的膨润土技术提供了战略框架，以支持更可持续、更高效的油气采收率。
