| 摘 要： | 苏里格庙气田主要产气层为上古生界石盒子组盒8段，属于三角洲平原分流河道沉积。复合砂体近南北向展布；单砂体的厚度变化大，非均质性明显，储渗变化大。盒8段含气砂岩在AVO资料上有明显反映；在综合测井资料上，盒8段表现出自然伽玛测井值、密度测井值、补偿中子测井值都偏低，电阻率、声波时差测井值较高，出现了大幅度的自然电位异常。利用核磁共振测井技术测得苏里格庙区某井盒8段3555．9m～3559．6m为气层，3560．6m～3572m为气水层，与生产实践吻合得很好。

| Abstract: | The main gas-producing interval in Suligemiao gas field of Erdos Basin is He-8 member of the upper Paleozoic era. The depositional facies of He-8 member in Suligemiao gas field belongs to the distributary channel of delta plain. The complex sand bodies extend along south and north direction. The thickness of single sand body varies greatly with obvious anisotropies. The reservation and infiltration characteristics the sand bodies change obviously. The gas-bearing sandstone of He-8 bodies are clear on AVO profiles. The values of natural gamma-ray, density and compensated neutron logging are low, while that of resistivity and acoustic logging are comparatively high. There are high anomalies on SP logging. From NMR materials we deduce that the interval from 3555.9 to 3559.6 meter is gas sand, and 3560.6 to 3572 meter is gas-water sand. |
