摘　　要：储层水淹层评价,尤其是针对碳酸盐岩地层的水淹层评价是当今石油开发中的一个世界性难题。针对碳酸盐岩地层的特点,提出裂缝孔隙度与电阻率交会图版法、井间电阻率与含水饱和度关系对比法、声波时差与电阻率曲线形态相关法、自然电位时间推移测井法等4种定性评价碳酸盐岩水淹层的方法。这4种方法可以从不同的角度对水淹层的水淹程度、水源及其水淹层位进行定性评价,从一定程度上填补了碳酸盐岩水淹层评价方法上的空缺。通过在ZL油田的实际运用表明,这几种方法具有各自的优点,结合现场情况,选择适合的方法对碳酸盐岩水淹层进行定性评价可以取得良好的效果。Evaluation of the water-flooded reservoir, especially the evaluation to the water - flooded layer of carbonate rocks is a global problem in the oil exploitation. Considering the characteristics of carbonate rocks, This paper Propose four methods, which include fracture porosity and resistivity intersection chart, water saturation and resistivity relation comparison among wells, acoustic and resistivity curve shape relation, Spontaneousness time-lapse logging way. These four methods may from the different angle to evaluation the flooding degree of the reservoir, the water source and water - flooded layer, has filled in the carbonate rocks water- flooded appraisal method vacancy from the certain degree. Through the practice applying in the ZL oilfield indicated that these methods have their own advantages. If according to the practice situation , selecting the appropriate method for qualitative evaluation water-flooded layer in the carbonate rocks can get good results.
