塔中卡1地区奥陶系良里塔格组碳酸盐岩储集体油气资源丰富，但其非均质性强、反射特征复杂，储层识别预测难度大。通过对卡1-顺西地区良里塔格组储层特征及主控因素的研究，分析了该区良里塔格组储层响应特征，并基于古地貌分析、断裂检测、属性叠合等技术，探讨了良里塔格组储层识别及预测的方法。结合构造、断裂带、古地貌特征，在良里塔格组下段-鹰山组上段落实了9个圈闭；结合油气成藏期次及油气富集规律，优选部署了ZL1井。

In the of the central Tarim Basin, carbonate reservoirs are found rich in oil and gas; however, they have a strong heterogeneity and show complicated reflection characteristics, which makes it difficult for reservoir identification and prediction. We studied reservoir response characteristics through the analyses of reservoir features and controlling elements of the Lianglitage Formation in Ka1 and Shunxi areas, and proposed some methods for reservoir identification and prediction combined with paleogeomorphy, fault and attribute analyses. Nine traps were determined according to the characters of structure, fault and paleogeomorphy. Well ZL1 was deployed based on petroleum accumulation period and enrichment regularity.
