地震数据处理解释一体化在隐蔽油气藏勘探中的应用(英文)
|
摘要
在全球石油高度紧缺的形势下,寻找剩余石油显得非常重要。但是,容易寻找的简单构造油气藏大都已发现,剩下未发现的油气藏大都是复杂构造、地层和岩性圈闭油气藏。用地震技术到底能不能找到那些复杂的隐蔽油气藏?这是本文所要探讨的内容和回答的问题。本文提出以AVO叠前处理解释为核心的地震数据处理解释一体化系统工程。一体化的处理解释流程保障了叠前和叠后信息的相互反馈,提高了数据利用的准确性和克服地震属性的陷阱;在油气藏评价过程中,与地质信息有机结合,找出最具代表油气特征的多参数进行综合评价,发现油气成藏规律与分布规律,最终达到精确地对储层描述与评价,提出有利圈闭和井位部署建议。本文是对隐蔽油气藏地震资料处理解释一体化所取得的经验的总结及对一些关键问题的探讨,并剖析了地震属性分析中的陷阱。
Nowadays, it becomes very urgent to find remain oil under the oil shortage worldwide. However, most of simple reservoirs have been discovered and those undiscovered are mostly complex structural, stratigraphic and lithologic ones. Summarized in this paper is the integrated seismic pro- cessing/interpretation technique established on the basis of pre-stack AVO processing and interpretation. Information feedbacks occurred between the pre-stack and post-stack processes so as to improve the accuracy in utilization of data and avoid pitfalls in seismic attributes. Through the integration of seismic data with geologic data, parameters that were most essential to describing hydrocarbon char- acteristics were determined and comprehensively appraised, and regularities of reservoir generation and distribution were described so as to accurately appraise reservoirs, delineate favorite traps and pinpoint wells.
