大庆油田化学驱精细地质研究及其应用新进展
New progress in fine geological research and its application in chemical flooding in Daqing Oilfield
摘要
Abstract
Most sandstone oilfields in China have entered high water cut stage or ultra-high water cut stage,and the application scale of chemical flooding for enhanced oil recovery(EOR)has been expanding annually.Based on the current situation of fine geology research on chemical flooding in Daqing Oilfield,new research progress,achieve-ments application and existing challenges are comprehensively described.In recent years,the spatial extention of internal architecture and flow shielding effect in thick oil layers are quantitatively and finely described through con-centrated research in Daqing Oilfield.By using multi-levels hierarchical description technique,methods for quanti-tatively describing remaining oil distribution at different chemical-flooding development stages are developed,pro-viding basis for further remaining oil potential tapping after chemical flooding.For different chemical flooding devel-opment methods,techniques for quantitatively describing microscopic remaining oil are established to clarify the oc-currence and distribution differences of remaining oil,distribution patterns of 3 types of sand bodies,geological fac-tors of reservoir micro-structural characteristics,as well as their relationship with polymer-flooding development ef-fect in Daqing Placanticline oilfield.The research lays a foundation for the sustained development and efficient ap-plication of tertiary recovery technology in Daqing Oilfield.关键词
