摘要

在华庆西部地区延10~长2油藏发现一些电阻率相对较低的油气层,经试油检验可获得较高的油气产量,这对测井识别油水层造成一定的困难。通过对研究区低阻油层成因的深入研究,结合钻井、测录井及试油情况,分析引起研究区部分油层呈现低阻特征的主要原因;同时综合试油数据与测井响应之间的对应关系,利用多种油水层识别方法综合识别油水层,从而提高研究区浅层油藏油水层识别准确性。
        Some oil and gas reservoirs with relatively low resistivity were found between Yan10 and Chang2 in the west of Huaqing region, higher production was obtained in oil test, which caused the difficulty in identifying oil and water layers.Based on the in-depth study of cause of low resistivity reservoir formation, combined with the drilling, logging and well testing conditions, main reasons for the low resistance characteristics of the reservoirs were analyzed. Meanwhile, based on corresponding relationship between the well testing data and the logging response, a variety of identification methods were used to synthetically identify the oil and water layers, in order to improve the recognition accuracy of oil and water layers in study area shallow reservoir.
