摘要
大庆油田北一区断东位于萨中开发区北部９８号断层以东，自投入开发以来，共进行了４次大的调整。从１９９５年开始又对该区块进行了二次加密调整。加密调整后油田产油量增加，含水下降。利用加密前后的产量衰减公式对调整区块进行了开发指标预测；到２００５年１２月，采用加密井网生产比采用原井网生产可多采出原油２７６．１６×１０４ｔ，提高采出程度１．６７％。到２０００年１２月，加密井网含水率比采用原井网降低了２．６４％。
Duandong in Beiyi area in Daqing oil field is situated in the eastern part of fault 98 in north Sazhong development area. Since it was developed four great adjustments had been conducted. Since 1995, the secondary infill drilling adjustment has been carried out in this area. After the infill drilling adjustment, the production has been increased and water cut has been declined. According to the production decline equations before and after infill drilling adjustment, the prediction of development index is carried out in this area,the production increased by 276.16×104 t and the recovery rose by 1.67%, the water cut will decline by 2.64% through secondary infill drilling adjustment.
