地震勘探技术在金坛地区盐穴建库中的应用
|
摘要
金坛盐穴储气库是我国自行设计、建造的第一个国家级储气库,它对于长江三角洲地区能源安全具有重要战略地位。江苏金坛地区大地构造运动对沉积岩和地表应力作用小、断裂系统不发育,盐岩厚且埋深适中,是建库的有利地区。利用三维高精度地震采集、处理和解释技术,认识盐层及顶底板地层岩性分布特征,识别断层及空间展布规律,建立了精确的地质模型,为井位部署、造腔施工和气库管理提供了的科学依据。该技术实施和应用,为我国其它地区油气库的建设积累了经验。
The Jintan salt cavern gas storage has an important strategic status for energy security in the Yangtze River delta.Our country independently design and construct the first national level gas storage.Jintan Jiangsu area is a favorable area to construct gas storage,in where,the tectogenesis has slightly effects on the sedimentary rock and the surface stress;the breaking system doesn't grow;the salt rock is thick and buried in suitable depth.We have known litho logic patterns of the salt bed and adjoining rocks,recognized faults and the rules of their space distribution,built the precise geological model by gathering,processing and interpreting the high precise 3D seismic data.What we do have provided the scientific basis for geometric arrangements of wells,cavities' making and construction,and managements of the gas storage.The implementation and application of the technology have accumulated experiences for constructing oil and gas storages in other area in our country.
