摘　　要：台兴油田阜三段油藏为典型的中低渗复杂断块油藏。初期采用大井距基础井网、长井段合注合采,油藏长期处于"注不进、采不出"低效开发状态。针对开发过程中暴露的问题,在开展油藏精细描述、细分层开发研究的基础上,采用对主力断块整体细分、小断块注采完善及滚动扩边的开发新思路,对油藏进行综合治理,开发效果得到明显改善,油藏日产油水平由15↑58 t/d,增加可采储量22.8×104 t,提高采收率6%,综合调整取得初步成功,为条带状复杂断块油藏有效开发积累了宝贵经验。Fu III member of Taixing oilfield is a typical complex fault-block reservoir with mid-low permeability.In long time,the reservoir was in the inefficent development state of＂no injection,no production＂due to the application of the wide spacing well pat tern and commingled injection and production in the early period.Against the problems exposed in development process and on the basis of reservoir description and layer subdivision development research,integrate adjustment was carried out by adopting the new method of main block subdivision,injection-production optimization of small fault blocks and rolling extension.As a result,obvi ous achievement had been made in development with daily oil production increasing from 15 t/d to 58 t/d,recoverable reserves in creasing by 22.8×104 t and recovery ratio increasing by 6 %.The success of integrate adjustment has accumulated valuable experi ence for the efficient development of the complex banded fault-block reservoirs.
