在“能源危机”的背景下,油田二次采油提高资源利用率,可提高生产效益,进一步满足社会对石油的需求。针对现阶段二次采油技术在着一些问题,分析其原因,针对二次采油效果受含水上升率评价系数制约、储量控制的程度制约和受其动用程度因素制约的三大技术原因,分别采取改善二次采油效果的措施,诸如采取将防砂冲散、对缓慢的腐蚀现象进行预防和防治套管变形的技术应对措施。
In the context of “energy crisis ”, secondary recovery of oilfields to improve resource utilization can improve production efficiency and further meet the social demand for oil. In the light of some problems in the secondary oil recovery technology at present stage, the reasons are analyzed. According to the three technical reasons that the secondary recovery effect is restricted by the coefficient of assessment of the rising rate of water cut-off, the degree of reserve control and the restriction by the degree of utilization, Secondary recovery measures, such as adopting sandstorms to disperse, slow down the phenomenon of corrosion prevention and treatment of casing deformation of the technical response.
