通过对岩心的仔细观察,结合其它资料评价沙四上亚段储层的物性,利用核磁录井资料详细计算Y176井沙四上亚段的储层储集空间参数。结果表明:沙四上亚段砂岩孔隙度属于超低孔—低孔、超低渗—低渗储集层。同时,对研究井区进行单井相分析、物源分析的基础上阐述了Y176井区沙四上亚段储层在平面上的展布和储层物性的变化。
Through careful observation of cores and other data to evaluate the physical properties of the reservoirs in the Upper Shahejie Formation, the parameters of reservoir space in the Upper Member of Shahejie IV of Y176 well were calculated based on nuclear magnetic logging data. The results show that the sandstone porosity of the Upper Es4 in Shahejie belongs to ultra-low porosity-low porosity and ultra-low permeability-permeability reservoirs. At the same time, based on single well facies analysis and provenance analysis, the reservoir distribution in the upper reaches of Shahejie formation in Y176 well and the change of reservoir physical properties are expounded.
