我们国家大多数的油藏都濒临水渠废弃期,采收率在百分之三十左右,不过大多数的原油仍在地下没有被开采出来。由于科学技术的持续进步,对于增强采收率技术的研究获得了显著的进展,进而给石油开采奠定了一定的基础。这篇文章比较详细的介绍了热力采油驱、气体混相驱、化学驱以及微生物驱这些三次采油技术的工作原理以及使用现状。现阶段对于采油技术的研究对于石油开采行业来说是特别重要的,所以石油开采领域需要增加对于高效环保材料的研究,并且也需要增强对于油气开发新型技术的研究。
Most of our country’s reservoirs are on the verge of ditch abandonment, with recovery rates around 30%, although most of the crude is still not being mined underground. Due to the continuous improvement of science and technology, significant progress has been made in the research on enhanced oil recovery techniques, which has laid a solid foundation for oil exploration. This article introduces in detail the working principle and current situation of these tertiary recovery technologies such as thermal oil recovery, gas-phase flooding, chemical flooding and microbial flooding. At this stage, the research on oil recovery technology is particularly important to the oil exploration industry. Therefore, there is a need to increase the research on highly efficient and environmentally friendly materials in the field of oil exploration and to enhance the research on new technologies for oil and gas exploration.
