利用大量的生产、测井及监测等资料对文留油田高含水后期剩余油分布进行了研究,指出剩余油主要富集于层内低渗透段、层间状况差异大且物性差的层;平面上动态注采对应差的部位、受井间渗流特征及大孔道等影响的滞留区、绕流区、起伏较大的微构造部位;低电阻储层的重新解释与综合判定,同时也探讨了老油田剩余油挖潜的主要方法,它包括井网重组、定向井、侧钻井、注水井更新、注水井调驱、间歇注水、水平井技术等工艺在文留油田的应用及效果,对矿场应用具有借鉴意义。
The distribution of residual oil in Wenliu Oilfield at the later stage of high water cut is studied based on a large amount of data of production, logging and monitoring. The results show that the remaining oil mainly accumulates in the low permeability section of the reservoir, On the dynamic injection and mining of the corresponding poor parts of the well by the inter-well seepage characteristics and the impact of large channels such as the retention zone, around the flow area, the ups and downs of the micro-structural parts; low resistivity reservoir reinterpretation and comprehensive determination, but also to explore The main methods for taping potential of residual oil in old oilfields include the application and effect of such technologies as well pattern reorganization, directional well, lateral well drilling, water injection well rejuvenation, water injection well control, intermittent water injection and horizontal well technology in Wenliu Oilfield. Application of reference.
