摘要
针对低渗透油田的开发问题,结合我国低渗透油田的开发现状,首先对低渗透油田的超前注水开发规律进行深入研究,提出低渗透油田后期调整对策,为提高低渗透油田的开发效率和产量奠定基础。研究表明:在油井生产的初期阶段,采用超前注水方案以后油井的产量相对较高,产量的递减速度也相对较慢,但是在后期开发的过程中仍然会出现含水量升高,产量递减问题,因此,在后期开发的过程中,工作人员必须确定合理的流压范围和采油强度,采取一系列的措施全面提高油田的产量和采油效率。
In view of the development of low-permeability oilfields,combined with the development status of low-permeability oilfields in China,first of all,an in-depth study of the advance water injection development rules of low-permeability oilfields was carried out,and countermeasures for late-stage adjustment of low-permeability oilfields were proposed to improve the development efficiency of low-permeability oilfields.The output lays the foundation.Research shows that in the early stage of oil well production,after adopting the advanced water injection scheme,the output of the oil well is relatively high,and the rate of production decline is relatively slow,but in the later stage of development,water content will still increase and the production will decline.Therefore,in the later development process,the staff must determine a reasonable flow pressure range and oil recovery intensity,and take a series of measures to comprehensively improve the output and oil recovery efficiency of the oil field.
