GeoEast地震数据管理与解释技术在松辽盆地中央古隆起带基底勘探中的应用

Seismic data management and interpretation techtechnique of GeoEast in basement exploration application of paleo-central uplift belt of Songliao Basin

GeoEast-iEco是全新研发的地震解释数据库建设平台,高效数据管理,支持各类数据批量加载和输出,支持多坐标系统下统一成图,满足盆地级地震解释成果数据管理需求;GeoEast V4.0是在GeoEast-iEco平台上开发的软件系统,集构造解释、地震属性分析、地震反演储层预测、叠后叠前裂缝地震预测等的综合地震资料解释系统平台,能解决油田地震资料解释及井位部署的需求。文中应用GeoEast-iEco数据管理平台和GeoEast软件解释技术系统,构建松辽盆地中央古隆起带基底地震解释数据库,基于iEco地震解释数据库,开展基底构造解释、岩性及储层地震预测、五维解释裂缝地震预测等技术应用,有效支撑了该区“十三·五”以来针对中央古隆起带基底的勘探部署,并见到了较好应用效果。

GeoEast-iEco is a newly developed platform for seismic interpretation database construction.Integrating many functions of efficient data management,batch data loading and output,and unified mapping based on multi-coordinate systems,it meets the data management requirements of seismic interpretation at the basin level.GeoEast V4.0 is a new software system developed on the GeoEast-iEco platform.It is a comprehensive platform of seismic data interpretation system integrating tectonic interpretation,seismic attribute analysis,reservoir prediction by seismic inversion,and post-stack and pre-stack fracture prediction with seismic data.Therefore,it can satisfy the demands of oilfield seismic data interpretation and well location deployment.This paper employs the data management platform GeoEast-iEco and software interpretation technology system GeoEast to establish the basement seismic interpretation database of the paleo-central uplift belt of Songliao Basin.By the iEco seismic interpretation database,the paper carries out technical applications of the basement tectonic interpretation,the lithology and reservoir prediction with seismic data,and the fracture prediction with seismic data based on five-dimensional interpretation.This study has supported the basement exploration deployment of the paleo-central uplift belt since the 13th Five-Year Plan and yields sound application effects.
