摘要
高17区块ES_3^(2+3)油藏是典型的非均质油藏,油层埋藏深,含油井段长,天然能量不足。注水开发以后,层间矛盾突出,水驱开发效果差。因此,在该区块开展油藏描述工作,先后进行了储层敏感性分析、物性与非均质性评价和储层微观孔隙结构分类评价等研究,确定了合理的注水强度、水质标准,并制定出相应的油层保护措施,为高17区块的开发调整、综合治理和小层段注水开发提供了依据,对于提高类似非均质油藏注水开发效果具有借鉴、指导作用。
Gao Block 17 (Es32+3 ) is a typical heterogeneous reservoir with deeper buried depth, longer oil-bearing intervals, and shortage of natural energy. After manual water injecting, the developing effect was not very ideal due to serious interzonal difference. In order to find out dependable evidences regarding development adjustment, comprehensive treatment, and fine water injection for Gao Block 17, plenty of reservoir description studies were proceeded involving evaluation to reservoir sensitivity, physical property and heterogeneous characteristic, and microcosmic pore structure category. Reasonable injection intensity, standard of water quality, and measures to corresponding reservoir protection were confirmed based on these studies. It will be very much helpful towards similar heterogeneous reservoirs in improving injection effect.
