摘要(Abstract)：

文东油田是处于油田开发中后期的高温、高压、高盐低渗透砂岩油藏,应用传统的套后剩余油饱和度监测技术以及利用常规电阻率测井资料确定水淹层剩余油饱和度效果不佳。在利用产出剖面资料确定水淹层剩余油饱和度方法研究的基础上,分析水淹层水淹程度的非均匀特征导致水淹层内剩余油饱和度的差异,通过面积等效法构建非均匀水淹层饱和度模型图,应用此改进方法确定出非均匀水淹层的剩余油饱和度。方法改进前后对比分析结果表明:方法改进后的计算结果更能反映水淹层的整体剩余油饱和度,与储层的实际情况更加符合,进而可准确掌握区域剩余油饱和度分布规律,为油藏的合理有效开发提供科学依据。
Wendong oilfield is a high-temperature,high-pressure,high-salt and low-permeability sandstone reservoirs,which is in the middle and late stages of the development,the determining methods of traditional after-casing remained-oil saturation monitoring technique and conventional resistivity logging data have lost their effects in the oilfield. On the basis of the researching methods of using the production profile data to determine the remained oil saturation in the watered-out layers,the saturation determining differences resulted from the heterogeneous characteristics of the watered-out degree for the oil layers stated above were analyzed,with the help of equivalent area method,the saturation model for the heterogeneous watered-out layers was established,and moreover by means of the improved method,the remained oil saturations of the layers were determined. The contrast and analysis before and after the improvement show that the calculated results of the latter can more reflect the overall remained oil saturation of the layers,and furthermore are much more accordant with the actual conditions of the reservoirs,thus can more accurately master the oil saturation distribution laws in the region. All these achievements have provided thescientific evidences for the rational and effective development of the oil reservoirs.
