摘要
油层微型构造(微构造)是指在总的油藏构造背景上,油层本身的细微起伏变化所表现出的构造特征,其幅度和范围均很小,通常相对高差在10m以内,面积很少超过0.3km2。可以分为正向微构造、负向微构造和斜面微构造。正向微构造一般为剩余油富集区,而负向微构造一般为低含油气区或易水淹区。对鄯善油田西Ⅱ区的微构造分析表明,正向微构造区油井的生产能力好,负向微构造区井的生产能力差。
The micmstructures of oil reservoir refer to occurring structural feature resulted from its own slight changing in overall reservoir structure background. Its changing and scope are small, with less than 10 m relative height difference and less than 0.3 km^2 area. The structures include positive, negative and inclined microstructure. The former one is area with abundant remaining oil and the second one is poor petroliferous area or easy water - out area. The analysis for microstructure in west Ⅱ region indicates productivity of oil wells in positive microstructure is better than that in negative microstructure.
