| 摘 要： | 塔里木盆地塔中地区奥陶系鹰山组是海相碳酸盐岩油气勘探的有利目标层位。为查明塔中地区卡1三维区块鹰山组台内滩储层的空间分布,基于大量的岩心、钻井、地震资料,通过井震对比,分析台内滩的地震反射特征,并在此基础上预测卡1区块内鹰山组台内滩的分布。研究认为,台内滩内部多具有高频无序反射,振幅的强弱变化明显,且不均匀,两翼地层厚度有较明显的变化,与相邻层位岩性有明显差异;在顶面和底面多具有宽、缓的透镜状或丘状地震反射波外形,台内滩附近的围岩,较明显地超覆或披覆在台内滩之上。在精细解释三维地震资料的基础上,利用地震属性,对鹰山组古地貌进行了恢复,预测卡1三维区块奥陶系鹰山组的台内滩有利发育区,为区内高能滩相储集层的评价奠定基础。

| Abstract: | The Ordovician Yingshan Formation in Central Tarim Basin, Xinjiang is interpreted as the favourable target horizons for the petroleum exploration in the marine carbonate rocks. The seismic reflection configurations and spatial distribution of the intraplatform shoals in the Ordovician Yingshan Formation in the Ka-1 threedimensional seismic area are based on the core examination, well logs and seismic data. These intraplatform shoals have high-frequency disordered seismic reflection waves, highly varied amplitudes, and sharp changes of the stratigraphic thickness on both sides, wide and gentle lenticular or mound seismic reflection configurations, and overlapping or draping of the wall rocks around the intraplatform shoals upon the intraplatform shoals. The palaeomorphological features are reconstructed for the Yingshan Formation, and the favourable areas are delineated for the intraplatform shoals in the Formation. The results of research in this study will provide the basic information for the assessment of the high-energy shoal reservoir rocks in the study area. |
