| 摘 要： | 双河油田厚油层发育，在目前特高食水期开发阶段厚油层内剩余油分布主要受井冈完善程度、地层纵向渗透性、砂你沉积特征、微构造及区域地层压力因素控制。剩余油在井网不完善井区、纵向中低渗透层、注采状况较差的分流河道沉积问及沉积末端、微构造高部位及局部注水压力平衡区相对富集。在完善井冈的基础上根据地层地质特征加强注来结构调整及注水合理调配，是汉河油田油层挖潜的有效途径．

| Abstract: | Thick oil reservoirs are highly developed in Shuangheoilfield. At current high water-cut stage, residual oildistribution in these thick reservoirs are mainly controlledby the completeness of well patterns, formation verticalpermeability, depositional features of sand bodies,micro -structure and regional formation pressure. Residualoil enrich in well blocks with incomplete well patterns, informations with medium to low vertical permeability, inregions between distributury channels or at terminals ofdistributary channels where injection- production are poor,at micro-structural highs and in local injection pressurebalanced areas. Effective ways to tap production potentialsof thick layers in Shuanghe oilfield are optimizinginjection - production structure and injection waterallotment in addition to completing well patterns. |
