摘　　要：分析了文 13北块的渗流特征、裂缝方向对水驱采收率的影响 ,利用主曲率法对该区块的裂缝分布规律进行了分析计算 ,并结合油藏构造特点及动态数据分析 ,探讨了不同层的裂缝分布规律。在此基础上 ,研究了井网的适应性 ,并对该区块的井网进行调整 ,使注采系统更符合地下情况 。The effect of perculation characteristics and fracture direction on the recovery of water flooding in North Block of Wen 13 is analysed. The fracture distributional Laws of the block are calculated analytically by using the method of main curvature, the fracture distributional laws in different layers are discussed in combination with reservoir structural characteristics and dynamic data analysis. On the basis stated, well pattern adaptability is studied and the well pattern in the block is adjusted, thus the injection producing system is more suitable to in-situ condition with good development effect.
