石油是一种廉价高效、不可再生的天然资源,其在能源、化工原料以及国防战略物资等方面发挥着不可代替的作用。在能源日趋紧张的情况下,提高能源采收率技术已成为石油开采研究的重大课题。石油的开采以及油田的开发过程可分为三个不同的阶段:一次采油、二次采油和三次采油。一次采油和二次采油都是利用物理方法进行的采油技术。三次采油技术是指一次采油和二次采油利用物理、化学、热量以及生物等先进的技术来改变岩石和流体密度,强化开采剩余石油储量的方法,以表面活性剂进行的三次采油技术得到人们的普遍关注,具有提高采收率效果好、适用范围广、发展潜力大等特点,本文以如何有效的开采水驱去后剩余油为出发点,最终确定表面活性剂驱油体系提高采收率的影响因素。
Oil is a cheap, efficient and non-renewable natural resource that plays an irreplaceable role in energy, chemical raw materials and strategic materials for national defense. In the increasingly tense energy situation, to improve energy recovery technology has become a major issue of oil exploration. Oil extraction and oilfield development can be divided into three distinct phases: primary recovery, secondary recovery and tertiary recovery. Both primary recovery and secondary recovery are physical recovery techniques. The third oil recovery technology refers to the first oil recovery and secondary oil recovery using physical, chemical, thermal and biological and other advanced technologies to change the rock and fluid density, and strengthen the method of mining remaining oil reserves, tertiary oil recovery technology to get people It is generally concerned with the characteristics of enhanced oil recovery, wide range of application and great potential for development. In this paper, how to effectively recover the remaining oil after water flooding is used to determine the effect of surfactant flooding system on oil recovery factor.
