缓释技术在油气田开发中的应用进展

Research on application of slow release technology in oil and gas field development

介绍了缓释技术的原理、应用领域和油田常用缓蚀技术的种类,分别从缓蚀阻垢、压裂液破胶、调剖堵水、油田监测、钻井固井等方面综述了缓释技术在油气田开发中的应用情况,发现将缓释技术应用于油田可有效延长活性物质的使用期限,改善储层非均质性,减少储层伤害和环境污染,节省人力物力,具有极大的经济、社会和环境效益。探讨了目前存在的不足及未来的研究方向,为缓释技术在油气田开发中的应用提供借鉴和参考。

Introduced the principle, application fields and types of slow release technologies commonly used in oilfields.The slow-release technologies were reviewed from the aspects of slow-release scale inhibition, fracturing fluid gel breaking, profile control and water shutoff, oilfield monitoring, drilling and cementing, etc.In the application of oil and gas field development, it is found that the application of slow-release technology in oil fields can effectively extend the life of active substances, improve reservoir heterogeneity, reduce reservoir damage and environmental pollution, save manpower and material resources, and have great economic benefits, social and environmental benefits.Discuss the current shortcomings and future research directions, and provide reference and reference for the application of slow-release technology in oil and gas field development.
