勘探、评价、开发阶段地震技术应用关键问题分析

摘要/Abstract

摘要： 地震技术作为解决油气勘探难题的核心技术，正在逐步向评价、开发阶段延伸。由于油气勘探、评价、开发阶段的地质任务、认识及资料基础不同，对地震技术需求不同，需要对不同阶段地震技术应用的关键问题进行梳理，达到提高技术应用针对性的目的。在勘探阶段，领域资料、区带资料、目标资料与地质认识基础薄弱，地震技术是不可或缺的手段。在评价阶段，约束条件比较明确，地震技术描述对象重点转移到有利岩性、储层物性、含油气性方面，精度要求远高于勘探阶段。在开发阶段，地震技术应用重点是描述储层及油藏的细节特征，地质家对地震技术依赖程度有所降低，但地震技术仍有较大的应用空间。

Abstract: Seismic technology is the core for petroleum exploration, and it is gradually extended to petroleum appraisal and development stages. In the petroleum exploration, appraisal and development stages, when the geologic tasks, understandings and available data are different, the requirements for seismic technology are varying. Accordingly, it is necessary to clarify key issues in application of seismic technology during different stages, so as to ensure the appropriateness of the technology. During the exploration stage with limited data available for the concerned area, prospects, specific target and geologic conditions, seismic technology is indispensible. During the appraisal stage with clarified constraints, seismic technology may be deployed to determine favorable lithologies, reservoir properties and oil/gas-bearing potential, with much higher accuracy required than that in the exploration stage. During the development stage, seismic technology is mainly used to highlight the detailed features of specific reservoirs and oil pools; though geologists are less dependent on seismic technology, the technology can still be extensively deployed.
