| 中文摘要:针对塔里木盆地温宿凸起区新近系砂岩储层厚度薄、单砂体厚度小、砂体相变快的特点, 通过研究分析砂体储层与地震属性、测井曲线之间的关系, 采用伽玛拟声波地质统计学反演方法对研究区新近系进行储层预测, 并与常规的波阻抗反演、声波测井约束地质统计学反演方法生成的预测结果进行了对比分析。结果表明, 本文采用的方法极大地提高了预测结果的垂向分辨率, 可以有效识别出薄层砂体。该预测结果有效支撑了井位优选, 并经过了新钻井钻探证实, 实现了该区油气调查的突破。 |

| Abstract:In view of the characteristics of Neogene sandstone reservoir in Wensu uplift area of Tarim Basin, such as thin thickness, small thickness of single sand body and fast facies change of sand body, the authors studied the relationship between sandstone reservoir, seismic attributes and logging curves, and predicted Neogene reservoir by using geostatistical inversion method based on gamma pseudo-sonic curve. The prediction results were compared with conventional wave impedance inversion and geostatistical inversion based on acoustic logging curves. The results show that the vertical resolution of the prediction results is greatly improved and the thin sand body can be identified effectively. The prediction result effectively supports the well location optimization, as verified by new drilling, thus realizing the breakthrough of oil and gas investigation in this area. |
