| 中文摘要: |
| 水驱油田的优势通道发育广泛,如何快速识别注采井间的水流优势方向可为后续的调剖堵水工作奠定基础。通过对油水井的生产动态分析,在相关系数与多元回归的基础上,并考虑注水延迟效应的影响之后,建立了一种快速识别水流优势方向的方法,并编制了相应的计算机程序。将该方法运用于实际油田区块,其所判断的水流优势方向结果与油田注采劈分结果一致,具有良好的实际使用效果。 |
| 英文摘要: |
| The dominant channel of water flooding oilfield is widely developed and how to quickly identify the dominant direction of water flow between injection and production wells can lay a foundation for the subsequent profile control and water plugging work. Based on the correlation coefficient and multiple regression and considering the influence of water injection delay effect, a method to quickly identify the dominant direction of water flow was established and the corresponding computer program was compiled. The method is applied to the actual oilfield block, and the result of the predicted flow direction is consistent with the oilfield injection and production splitting, which has a good practical application effect. |
