摘　　要：储层流体性质识别是勘探阶段油藏基础描述之一,因此对西峰油田开展流体性质识别工作,对勘探开发有重要意义。本文以西峰油田ZT井区的延10储层为例,结合生产、地质资料进行测井孔隙度—渗透率模型和孔隙度—声波时差模型的建立,最终对研究区进行流体性质识别,对比各类方法的优越性和适用性。结果表明:延10储层的油层电阻率偏低,不利于进行含油性辨别,并且储层的油水高侵,低侵不明显,流体性质也不易识别,根据探井数据、测井曲线响应来看,仅有邻井对比法及油层最小电阻率法在该研究区可适用,且效果良好。对西峰油田ZT井区延10储层流体性质进行定性识别,筛选出适用于该研究区的流体性质识别方法,对该研究区后续油田勘探开发具有借鉴意义。Reservoir fluid property identification is one of the basic reservoir description in the exploration stage,so it is of great significance for Xifeng oilfield to carry out fluid property identification.In this paper,yan10 reservoir in ZT well area of Xifeng oilfield is taken as an example to establish the porosity-permeability model and porosity-acoustic time difference model combined with production and geological data,and finally to identify the fluid properties in the study area and compare the superiority and applicability of various methods.Results show that the yan10 reservoir of low resistivity reservoir,conducive to discern oiliness,and reservoir oil-water high invasion,low contamination is not obvious,fluid properties and not easy to identify,according to exploratory well data and log response,only adjacent wells correlation method and the minimum reservoir resistivity method can be used in the study area,and the effect is good.The fluid properties of yan10 reservoir in ZT well area of Xifeng oilfield were qualitatively identified,and the fluid properties identification method suitable for this research area was selected,which has reference significance for the subsequent oilfield exploration and development in this research area.
