摘　　要：在严重的油藏非均质情况下,特高含水开发期坨21断块沙二1-7单元地下剩余油潜力具有“厚度薄、分布零散、面积小、油层物性差、驱替能量低”的特点,利用三次加密、层系细分等传统井网调整技术来挖掘这部分潜力,经济效益变差。围绕高含水期井网综合调整这一核心,通过系统的开发地质及油藏工程的研究,取得了一些重要的成果和认识。The underground residual oil potential in Sha-2 1-7 Unit of Tuo-21 Fault Block has such features as thin thickness, scattered distribution, small area, poor oil layer physical properties and low driving energy under serious heterogeneous reservoir conditions. By using traditional well pattern adjustment techniques, such as three-time infill well and subdivision of stratigraphic sequences, tbis part of potentials is exploited, and the economic benefits change for the worse. Focusing on the heart of eomprehensive well pattern adjustment, some important outcomes and knowledge are elicited through the systemic studies of geology and reservoir engineering.
