GeoEast特色解释技术在柴达木盆地仙东地区的应用

Application of GeoEast's characteristic interpretation methods in Xiandong area of Quadam Basin

柴达木盆地地表条件复杂,造成地震资料信噪比低,提高资料信噪比是迫切需要解决的问题。研究区构造相对简单,以岩性油气藏为主。储层单层厚度小,依据地震资料难以预测。该区钻井分布不均,沉积相带认识不清。GeoEast地震资料综合解释系统是东方地球物理公司开发的一套大型处理解释一体化软件系统,文中基于GeoEast解释系统在柴达木盆地仙东地区开展了地震地质综合解释,在地震资料精细解释、属性分析和油气检测方面均取得较好应用效果,在精细构造落实、油气分布规律研究方面效果明显,为寻找油气有利区提供了依据。GeoEast一体化解释平台功能齐全,适用性强,在多属性分析方面有着突出的应用效果。

Due to complicated surface conditions,the seismic data of Qaidam Basin has a low signal-tonoise ratio(SNR),and hence,data with a higher SNR is in urgent need.The simply structured study area is dominated by lithological hydrocarbon reservoirs with thin layers,which can hardly be predicted given the seismic data.Moreover,drilled wells are unevenly distributed in this area,and the understanding of the sedimentary facies zone is insufficient.GeoEast,developed by BGP Inc.,is a large software system integrating seismic data processing and interpretation.In this paper,GeoEast is used for comprehensive seismic geology interpretation in the Xiandong area of the Qaidam Basin,which has achieved good application results in seismic data interpretation,attribute analysis,and hydrocarbon detection.In addition,it boasts prominent effects in research on the fine structure and hydrocarbon distribution laws in the study area,which provides a reference for the search for favorable hydrocarbon areas.GeoEast,a fully functional integrated interpretation platform,has a wide application scope and outstanding application effects in multi-attribute comprehensive analysis.
