摘　　要：采用油藏数值模拟方法 ,对胡 12块的开采历史进行了拟合 ,得出了剩余油分布状况 ,找出剩余油富集区域横向上主要集中在各层系或构造的高部位 ,西块的剩余油主要集中在Es中3亚段 7砂组和Es中3亚段 6砂组 1～ 3砂层 ,其次在Es下3亚段 1砂组 1～ 4砂层沿胡 77断层及石家集断层一带 ,且连片性较好。东块剩余油主要集中在Es中3亚段 4砂组、 12 7井北面及其东北和西南方向约 2 0 0～ 3 0 0m内 ,其他层系的剩余油饱和度都比较低且十分分散。同时还设计了 4个调整方案进行了 10年的开发预测 ,通过对这4个方案开发指标的对比分析 ,推荐采用方案 3。Production history match is conducted on Block Hu 12 by using reservoir numerical simulation. Residual oil distribution is obtained. It is found that oil abundance area is concentrated laterally on top of each stratum and structure, the residual oil on the west block is concentrated on Sand Group 7 and Sand 1~3 of Sand Group 6 in the middle position of Es 3, the other oil abundance areas are concentrated on Sand 1~4 of Sand Group 1 in the lower position of Es 3 along 7-7 fault and Shijiaji fault with good connection. The residual oil distribution is principally concentrated on Sand Group 4 in the middle position of Es 3, to the north of Well 12-7 and within 200~300m in the north-west and south-west . The residual oil saturation of the other strata is low and highly dispersive. At the same time 4 adjustment plans have been designed for 10 years production prediction, of which the indications are comparatively analyzed. Plan 3 is recommended to be introduced in oilfields.
