| 摘 要： | 在分析了 Z 油田 5 个超前注水实验区基本情况的基础上，应用注采平衡分析方法，采用理论分析和区块动态分析相结合的方式，运用数值模拟评价了实验区的井网适应性。通过分析地层压力与油水井数比关系、相对采液量与油水井数比关系、地层压力与吸水产液指数比关系及不同井网形式含水与采出程度关系，明确了井网形式对地层压力、采油速度及含水上升规律的影响。分析结果表明：地层压力随油水井数比增高而单调递减，通过调整井网提高产液量还有较大的空间，井网形式与含水上升之间关系不明显。

| Abstract: | Based on the analysis of 5 experimrntal areas of advanced water injection, adaptability of well well network in thye study area is numerically simulated with the analysis method of balancing between injection and production and by combining theoretical and dunamic analysis of study area. After analyzing the relationship between pressure and number ratio of oil well and water well, between contra output of liquid and number ratio oil well and water well, formation pressure and production fluid index with water absorption and that water percentage of different well network and output degree. The authors clarify the influence of well network on formation pressure, oil producing rate and increase of water percentage. The analysis reveals that formation pressure monotone decrease with the increasing of ration of oil and water well, and that fluid production can be increased by adjusting wellnetwork and there is no clear relationship between well network and increasing in water percentage. |
