摘要
准噶尔盆地春光地区主要发育透镜体岩性油气藏,储层为薄层的滩坝砂体。针对该种薄层储层特征,以油气层地震-地质综合分析为起点,以保幅纯波地震资料为基础,应用多属性综合分析、频谱衰减和子波重构等技术进行油气检测。应用结果表明,油气检测目标最好具备同层位、同相带、同圈闭类型、小单元等条件,多属性综合分析和频谱衰减油气检测技术具有一定的可行性,子波重构油气检测技术更可靠,并通过钻探取得了证实。
The lenticular lithologic reservoirs were mainly developed in Chunguang Block of Junggar Basin and the depositional type was thin layered beach bar.Based on the characteristics of thin reservoir,integrated analysis of seismic-geology of oil and gas layer and amplitude-maintained and pure-wave seismic data,oil and gas were detected by using the technologies of multi-attribute comprehensive analysis,frequency attenuation and wavelet reconstruction.The result shows that the detection would be more precise when the target reservoirs are small and have the same trap type and lie in the same stratum or the same phase belt.The techniques of multi-attribute analysis and frequency attenuation have certain feasibility to detect hydrocarbon in Chunguang Block,but wavelet reconstruction technique is more reliable and effective than the other two,it is proven by drilling.
