摘要(Abstract)：

缝洞型油藏具有多缝洞、多压力、多渗流单元的特征,储层强非均质性影响了注水开发效果。为避免油藏注水后存在水驱均衡性差、部分井水窜严重等问题,需迫切开展井间连通性研究。目前基于注采生产数据的多元线性回归模型(MLR),多采取最小二乘法、遗传算法、拟牛顿法等参数求解方法,以获取表征注采井间动态连通系数。由于缝洞型油藏储集层复杂,在传统研究基础上,研究采用局部经验模态分解(LMD)对生产数据去噪,并应用高斯估值对考虑时滞性的多元线性回归模型进行参数求解。应用所建模型对塔河油田部分井组进行了井间连通性反演,反演结果和真实示踪剂测试结果吻合,表明所建模型能够定量表征油藏井间连通性。
