沈84块精细油藏描述研究

Study on fine reservoir description of Shen 84 block

为了进一步提高沈84块开发效果,对沈84块18个四级断块进行了分类评价和潜力分析,对全区目的层段地层、构造、沉积微相、油层分布特征及全区开发效果进行了分析评价,优选潜力断块区,多学科、多技术相结合进行油藏地质建模、数值模拟及剩余油分布研究。提出了改善油藏开发效果的对策,对同类油藏精细油藏描述研究具有一定的借鉴意义。

In order to improve the development effect at Shen 84 block,the fine reservoir description was carried out and 18 Class 4 faulted blocks are evaluated and their potentials are analyzed in accordance with their catalogue.,The formation,structure,sedimentary microfacies,oil distribution features and development effect are analyzed and evaluated for the target interval in the whole area;thus potential blocks are optimized by establishing geological model by combining with multidisciplinary subjects and various techniques,numerical simulation and remaining oil distribution.Consequently,the countermeasures for improving development effects are pro-posed.
