摘要
油页岩是一种富含有机物的沉积岩,我国已探明的油页岩资源储量位居世界第三位,实现油页岩资源的商业化开发是保证我国能源安全的重要举措之一。油页岩地下原位转化法开采具有绿色环保、占地面积小、可开发深部油页岩资源等优点,是实现中深层油页岩资源高效开发的重要技术手段。文章介绍了水力压裂、超临界CO_(2)压裂、酸化压裂、清水压裂等储层改造技术在油页岩原位开采过程中的应用情况和研究成果,并对比了4种储层改造技术的优缺点。同时,重点阐述了目前油页岩水力压裂技术在实验研究、数值模拟及先导试验研究方面的应用及进展。最后,论述了目前油页岩储层改造技术的不足与未来发展方向。
Oil shale reservoirs are a kind of sedimentary rocks rich in organic matter.The proven reserves of oil shale resources in China rank third in the world.Realizing the commercial development of oil shale resources is one of the important measures to ensure the energy security of our country.Oil shale underground in‑situ conversion process has the advantages of green environmental protection,small footprint and can develop deep oil shale resources.It is an important technical means to realize the efficient development of middle and deep oil shale resources.This paper introduces the application and research results of hydraulic fracturing technology,supercritical CO_(2) fracturing technology,acidizing fracturing technology and clear water fracturing technology in the process of in‑situ exploitation of oil shale,and compares the advantages and disadvantages of four kinds of reservoir reconstruction technology.Meanwhile,the current applications and progress of hydraulic fracturing technology in experimental research,numerical simulation and pilot test project are highlighted.Finally,the deficiency and future development direction of oil shale reservoir reconstruction technology are discussed.
