Y133井区目前已经步入含水快速上升的前期,而目前实际地质采出程度还很低。通过对井区储层精细划分小层的基础上进行非均质性深入剖析,为该油田改善开发效果,实现高产、稳产的探索提供依据。利用钻、测、录井等资料统计分析进行综合分析,发现Y133井区储层整体上渗透性差,微观非均质性较强。宏观非均质性研究显示,长6113砂层组层内非均质性在六个小层里非均质性最强,以相对均质型和非均质型为主;长6323和长6123砂层层间非均质性相对较弱,长6113砂层层间非均质性最强;平面非均质性研究表明,沉积相带控制着储层物性的好坏,高孔高渗带所处的位置为浊积水道微相。其研究成果对制定合理注水开发技术策略提供了参考依据。
Well Y133 has now entered the early stage of rapidly rising water cut, but the current actual geological recovery is still very low. By in-depth analysis of heterogeneity on the basis of subdividing fine reservoirs in well area, this study can provide the basis for improving development effect and realizing high yield and stable yield in this field. By using the statistical analysis of data of drilling, logging and logging, it is found that the permeability of reservoir in Y133 well is poor and the microscopic heterogeneity is strong. The results of macro-heterogeneity show that inhomogeneity in the long 6113 sandstone layer is the strongest in six small layers, and is relatively homogeneous and heterogeneous; the length of 6323 and the length of 6123 The interlayer heterogeneity is relatively weak, and the interlayer heterogeneity is the strongest in the long 6113 sandstone. The study of plane heterogeneity shows that the sedimentary facies controls the physical property of the reservoir, and the high porosity and permeability zone The location of turbid water channel microfacies. The research results provide a reference for formulating a reasonable water injection development strategy.
