摘　　要：油层微型构造(微构造)是指在总的油田构造背景上,油层本身的微细起伏变化所显示的构造特征。微构造可分为正向微构造和负向微构造。正向微构造一般为剩余油富集区;负向微构造为低含油气或易被水淹区。马岭油田北三区生产实践证明,正微区的生产井效果好,负微区生产井效果差。在确定加密井网井位时,应考虑微构造因素,尽可能的把加密井钻在正向微构造区。Oil-bearing reservoir ministructure is called microstructura,means small highs and lows exhibited on its overall background. Microstructura can be divided into positive ministructure and negative ministructure. The former ones are regions of oil and gas enrichment and the later ones are regions where severe water invasion occurs. According to developmental practice in North Ⅲ block of Maling oilfield, wells located on the positive ministructures are better than those on negative＇ministructures. In the designing of well locations,according to ministructure, full wells should be drilled on the positive strut ture areas .
