对于靖安油田张渠二区长2储层宏观非均质性进行评价。在储层沉积微相研究基础上,综合运用岩心观察、测井资料,对研究区长2储层宏观非均质性进行研究。研究结果表明:研究区长2储层层内、层间储层宏观非均质性中等,长211-长212与长212-长213的隔层较厚,平均厚度10 m以上且非均质性偏弱,说明封盖性较好。长213层内划分小层隔层厚度小于1 m且非均质性强,连通性好。
The macro-heterogeneity of Zhang 2 reservoir in Jingan Oilfield is evaluated. Based on the study of reservoir sedimentary microfacies, macroscopic heterogeneity of reservoir No.2 in the study area is studied synthetically by core observation and logging data. The results show that the macroscopic heterogeneity of interlayered reservoirs is middle in the reservoirs of Chang 2 and Chang 2 reservoirs, and the interbeds of Chang 211 - Chang 212 and Chang 212 - Chang 213 are thicker with an average thickness of over 10 m and are heterogeneous Sexual weakness, indicating a better capping. The length of 213 layers is divided into small layers with thickness less than 1 m and strong heterogeneity, good connectivity.
