准噶尔盆地霍玛吐背斜带紫三段储层孔隙结构分形特征及评价
|
摘要
基于物性、铸体薄片、扫描电镜、恒速压汞等实验数据,利用分形几何的基本理论,对准噶尔盆地霍玛吐背斜带紫三段储层微观孔隙结构进行了系统研究。研究结果表明:霍玛吐背斜带紫三段储层孔隙类型以原生粒间孔和剩余粒间孔为主,喉道以缩颈型喉道为主,且大多是中喉。分形维数与物性、微观孔隙结构参数具有较好的相关性,可以综合表征孔隙结构的复杂程度,弥补了单一参数在反映孔隙结构方面的不足。霍玛吐背斜带紫三段储层孔隙结构类型以Ⅱ类中孔中喉为主。
Based on analyses of casting thin section,scanning-electron micro-scopes,X-ray,constant-rate mercury injection and the fractal fundamental theory,the micro scopic pore structure of the E2-3z3 reservoir in Huomatu anticlinal zone of Junggar basin were studied. The results show that the types of E2-3z3 reservoir pores mainly consist of primary intergranual pore and residual intergranual,the throats are mainly necking throats and medium throats. The fractal dimension has good correlation with physical property and micro-structure parameters,thus it can be seen that the fractal dimension can reflect the complexity of the pore- structure synthetically and make up the deficiency of a single parameter in reflecting pore-structure. The pore-structure of the E2-3z3 reservoir in Huomatu anticlinal zone is mainly type Ⅱ、medium pore and medium throat.
