黏土稳定剂在石油行业的应用进展

Application progress of clay stabilizer in petroleum industry

在油田开发的过程中时常会遇到黏土矿物的水化膨胀及分散运移,引起储层的堵塞进而损害储层。国内外学者研发了许多的黏土稳定剂来尽量避免这种情况的发生。随着油气资源向深层、高温、裂缝及低渗发展,大多数黏土稳定剂已无法满足复杂地层下的开发的要求。因此,黏土稳定剂也就成为了重要的研究课题。将黏土稳定剂按照应用领域划分为3类:油田勘探用黏土稳定剂、油田开发用黏土稳定剂和油田维护用黏土稳定剂,并综述了各个领域黏土稳定剂的发展现状、进展和发展趋势及相应的评估和建议。

In the process of oilfield development,hydration expansion and dispersion migration of clay minerals are often encountered,causing blockage of the reservoir and damaging the reservoir.Domestic and foreign scholars have developed many clay stabilizers to avoid this situation as much as possible.However,with the development of oil and gas resources from deep layers,high temperatures,cracks and low permeability,most clay stabilizers have been unable to meet the development requirements of complex formations.Therefore,the clay stabilizer has become an important research topic.The author divides the clay stabilizer into three categories according to application fields:clay stabilizer for oil field exploration,clay stabilizer for oil field development and clay stabilizer for oil field maintenance,and summarizes the development status,progress and development trend of clay stabilizers in various fields and the corresponding evaluation and suggestions.
