摘要/Abstract

摘要： 为了满足大庆油田长垣外围特低渗透扶杨油层精细水驱挖潜的需求，常采用油藏分类界限的方法对投产初期的区块进行合理分类。对于多个分类参数介于不同分类结果的特低渗透区块，该方法却加剧了划分结果的不确定性。为了解决这一问题，在已有长垣外围特低渗透扶杨油层分类界限成果的基础上，建立了多参数聚类分析、动静态一致性检验与综合评判分级相结合的油藏分类方法，明确了两大类、四小类区块的分类评价标准，并对各区块分类结果进行了验证。结果表明：该方法解决了个别区块分类参数介于不同分类结果造成的分类困难等问题，实现了63个已开发特低渗透区块的合理分类，并且具有计算简便、精确度高的特点，为大庆油田新投产特低渗透区块的高效精细分类提供了有力的依据。

Abstract: In order to meet the demand of fine waterflooding of Fuyang oil reservoir with ultra-low permeability around placanticline of Daqing Oilfield,the method of reservoir classification limit is usually used to realize the reasonable classifications on ultra-low permeability reservoir blocks at early stage of production. However,for some ultra-low permeability blocks,different classification parameters fall into different classification results, which exacerbates the non-determinacy of results. To solve this problem,on the basis of existed achievements of classification limits for Fuyang oil reservoirs with ultra-low permeability,the method combined multi-parameter cluster analysis,dynamic and static consistency test with comprehensive evaluation was established. The classification evaluation criteria for two groups and four sub-groups were determined,and the classification results of each block were verified. The results show that this method solves the problem of classification difficulty caused by different classification parameters of individual blocks falling into different classification results,and realizes the reasonable classifications of 63 developed ultra-low permeability blocks. In addition,it has the characteristics of simple calculation and high accuracy,which provides a powerful basis for efficient and fine classifications of ultra-low permeability blocks in Daqing Oilfield.
