| 以注水开发40多年的胜坨油田一区沙二11层为例,综合不同时期地质、测井及开发动态资料,通过划分动态井网单元,连续追踪油藏井网布局变迁及开发动态变化,定量表征储层所经受的水驱程度,利用多元线性回归分析拟合储层参数随水驱程度的数学演化模型,并计算出开发不同阶段的储层参数,建立基于油藏开发动态的储层四维模型。研究表明:储层参数演化数学模型能够根据开发动态将油藏开发初始时期储层参数统一到开发后的任意时期,有效扩充各个时期地质建模数据点的数量和分布范围;基于油藏开发动态的储层四维模型不仅能够直观和定量地表征储层参数在历史时期的空间展布规律,还可通过油藏开发趋势分析对未来储层参数分布状态进行预测。 |

| Abstract: |
| Taking the 11 layer of second member of Shahejie formation in Shengtuo Oilfield exploited by waterflood for more than 40 years as an example, a mathematical evolutionary model of reservoir properties correlated with reservoir performance was achieved by delimiting the dynamic well pattern unit, tracing the well pattern and development performance, characterizing the water drive degree quantitatively and using the multivariate regression analysis. The reservoir properties in different phase were figured out, and a 4D reservoir model was set up based on reservoir development performance. The results show that the reservoir properties value in initial development stage can be transformed to arbitrary stage by mathematical evolutionary model. The quantity and distribution range of modeling data in different development stage can be enlarged efficiently. Not only could the 4D reservoir model based on development performance characterize the past and present spatial distribution of the reservoir properties visually and quantitatively, but also forecast the future reservoir properties by using development trend analysis. |
