安塞油田塞160区块长6油藏试井资料解释与应用

Interpretation and Application of Well Testing of Chang6 Reservoir of Block Sai160 in Ansai Oilfield

安塞油田塞160区块长6油藏储层裂缝发育,试井资料解释过程中主要采取均质、裂缝及复合模型。随着开发时间的不断延长,油层压力分布不均,严重影响到区块的开发效果。根据2008年塞160区块54口油水井试井资料的解释结果,结合历年同井试井资料进行分析评价,为该区块今后的高效开发提出了调整意见。

In light of Chang 6 reservoir fractures of block Sai 160 are relatively developed, homogeneity, crack and composite model are mainly employed to interpret well test. Continuous operation has resulted in unequal distribution of reservoir pressure which has a serious impact on the block＇s opening up. According to interpretation of well testing data of 54 oil -- water wells of Block Sai 160 in 2008 and combined with analysis and evaluation on well testing data of the same wells over the years, this paper presents its suggestion on adjustment of the future efficient ex- ploitation in the block.
