活性水降压增注及驱油技术研究

Study of active water for decompression and augmented injection

开展了低渗透油田的表面活性剂降压增注技术研究,通过油房庄长_1吴旗长_2油藏基本概况、储层特性、油水性质、储层伤害机理、以往改造措施等进行了广泛深入的调研和研究,开发的活性剂体系配方具有很好的耐温性、耐盐性和抑制粘土膨胀,同时压率可达到20%～30%以上,具有很好的现场使用前景。

The technique of surface acting agent decompression and augmented injection in low - permeable oil was studied.In this paper, the oil pool survey,reservoir character, profit character, the mechanism of reservoir damage and reforming measures have been researched,then the good systems of active agent was screened,which have good temperature and salinity tolerance, rejection capability, and make the ratio of decompression can be up to 30 %, have better application prospects.
