Yong 8 block is a complex fault block oil reservoir, if vertical wells were only applied in the development, not only well spacing density would be big and producing time would be long, but also low production and poor development benefit would appear after sand control. 永8块为复杂断块油藏,若全部采用直井开发,不但井网密度大、开采时间长,而且直井防砂后产量低,开发效益不明显。
Improving vertical resolution for density curves is by means of restructuring the response from large and small spacing sondes and borehole effect correction factor and coherence factor are used. 提高密度测井曲线垂直分辨率是通过对重新组合长、短源距探测器响应的算法来提高补偿密度曲线的垂直分辨率,并加入井眼影响校正因子和相关性因子;
