摘要
塔里木盆地卡塔克1区块(卡1区)碳酸盐岩具有较好的油气勘探前景,但是该区缝洞储集体规模较小、埋深较大,纵横向非均质性强,给储层预测增加了难度。通过已钻井地震属性敏感分析研究认为,频率衰减梯度属性对储层含流体性具有较好的反映,并将其应用到储层预测工作中,指出了该区有利区带主要沿着东向断裂带呈不规则片状分布,位于构造高部位和斜坡部位,部署了Zhong101井、Zhong121井、Zhong122井等3口井。
The carbonate in Block Kartake 1 of Tarim Basin had better prospects of exploration for oil and gas,but vuggy reservoirs in this area were smaller,deeper with strong and vertical heterogeneity,which increased the difficulty for reservoir prediction.Through analysis of attributes sensitivity of drilled wells,it indicates that the frequency attenuation gradient reflects well to the reservoir fluid and it is applied to the reservoir prediction,which obtains good effect,the technology can be used as an effective technique in Tazhong Area.
