摘　　要：段六拨油田是大港油区的多层非均质低渗透砂岩油藏 ,因储集层物性差、非均质性强 ,1985年投入开发后处于低速低效开发的状态。通过深入研究油藏地质特点、储集层流体渗流特征 ,建立了改善开发效果的开发模式。 1996～ 2 0 0 1年进行整体综合调整 ,总井数增加 1倍而产量上升 10倍 ,段六拨油田整体开发水平由三类上升到一类。图 2表 2参 5 (张家良摘 )Duanliubo reservoir in Dagang oil field was put into development in 1985. Due to low permeability and strong and heterogeneity, this sandstone multi layer reservoir kept a low production rate and low efficiency after development. After analyzing the main factors which affect the production, such as geology and fluid factors, a development model which is suitable for Duanliubo reservoir was found. From 1996 to 2001, adjustment was done to improve Duanliubo development level. The wells doubled, and their production was increased by 10 times. The full field development was greatly improved.
