This work offers a new insight into the structural architecture and 3D representation of Qishn sandstone reservoir along Sharyoof field which is located at Say’un–Masilah basin in Hadramawt Province, Yemen. The 3D representation depends mainly on the integration of wireline logging data with 2D seismic lines along the Sharyoof field. The workflow of this study includes the interpretation of well logging data, tying the well data with the horizons along the 2D seismic lines, and manual interpretations for the seismic data to construct time structure contour maps. The check shot data was used to construct a velocity model which used to convert the resultant maps from time to depth. Finally, results were integrated to construct a 3D structural model for the Sharyoof field. The depths of 4 main formations tops (Fartaq, Harshiyat, Qishn, and Sa’ar formations) and their members were determined by the well logging data based on their lithological content. Seismic interpretation shows 6 main gentle dipping, planer, normal faults of NE–SW affecting the pre and syn depositional formation. Some of these faults extend to shallow depths affecting the post-rift Tertiary formations. The structural architecture of the Sharyoof field is mainly affected by the Early Cretaceous rifting between the African–Arabian and Madagascar–Indian which leads to the reactivation of the Najd fault system and the initiation of these NE–SW normal faults. The increase of the hydrocarbon productivity along the Sharyoof field requires drilling a new development well which suggested being north–east the current wells, as the hydrocarbon potentiality is mainly concentrated along this area.

这项工作为位于也门哈德拉毛省的 Say'un-Masilah 盆地的 Sharyoof 油田沿线的 Qishn 砂岩储层的结构结构和 3D 表示提供了新的见解。3D 表示主要取决于沿 Sharyoof 油田的电缆测井数据与 2D 地震测线的整合。本研究的工作流程包括测井数据解释、将井数据与沿二维地震线的层位联系起来，以及对地震数据进行人工解释以构建时间结构等高线图。检查射击数据用于构建速度模型，该模型用于将生成的地图从时间转换为深度。最后，整合结果以构建 Sharyoof 油田的 3D 结构模型。4 个主要地层顶部（Fartaq、Harshiyat、Qishn、和 Sa'ar 地层）及其成员由基于其岩性含量的测井数据确定。地震解释显示 NE-SW 的 6 个主要的缓倾、平面、正断层影响了前和同沉积地层。其中一些断层延伸到浅层，影响裂谷后第三纪地层。Sharyoof 油田的构造结构主要受早白垩世非洲-阿拉伯和马达加斯加-印度之间的裂谷影响，导致 Najd 断层系统的重新激活和这些 NE-SW 正断层的萌生。沿 Sharyoof 油田增加油气产能需要钻一口新的开发井，这表明在现有井的东北方向，因为油气潜力主要集中在该地区。
