摘　　要：以荣兴屯油田储层特征研究成果为基础 ,以室内实验数据为依据、通过现场取样和化验分析 ,对荣兴屯油田储层吸水能力下降的原因进行了综合性研究分析 ,结果表明 :荣兴屯油田注水井吸水能力下降的主要原因是储层自身物性差、注入水水质不合格、注入水与产层不配伍及不适宜的注水强度。研究成果为荣性屯油田的增注措施提供了可靠的依据 ,同时它对研究和分析其它砂岩油田注水井吸水能力下降的原因也有重要的意义。A comprehensive study has been made on the descendent injectivity of injection wells in Rongxingtun oilfield, based on experimental data, in?situ sampling and analyses. The results show that the descendent injectivity could be largely accounted for by poor reservoir quality, poor quality of the injection water, the incompatibility of the water injected and that in the formation, and the improper intensity of injection. Conclusins made in the work provided valuable reference for the further injection measures in this field.
