摘要
增储上产、降本增效是企业的追求目标,最大限度地提高采收率是油田开发的永恒主题。江汉油区经过40多年开发,油藏分类治理在油田开发中起着越来越重要的作用。从不同类型油藏开发趋势分析入手,结合江汉油区实际,对开发的具体油藏进行分类,明确整装油藏、复杂断块油藏、低渗透油藏和特殊油藏4种油藏类型中的重点开发单元的治理对策。现场实践表明,油藏开发效果得到显著改善,对持续推进油藏分类治理,确保区块产量稳定具有重要的现实意义。
Increasing reserves and production,lowering cost and improving efficiency were the object of oil enterprises,and they are the key to maximize oil recovery in oilfield development.Jianghan Oil Region has been developed for more than 40 years,the reservoirs classified control played an increasingly important role in oilfield development.The trend of different reservoir development was analyzed,and in combination with the actual situation in Jianghan Oil Region,the developed reservoirs were classified,the countermeasures of key developed units of integrity reservoirs,complex fault block reservoirs,low permeability reservoirs and special reservoirs were clarified.The result shows that the effect of reservoir development is obviously improved it is of great significance for maintaining the reservoir classification and control and stabilizing the production in the block.
