3.5维地震勘探方法及其应用研究
|
摘要
3.5维地震勘探是在油田开发中、后期结合高精度三维地震与油田开发动态信息的地震、地质、测井和开发等信息的综合地震勘探方法,该方法可以有效地解决油田开发中遇到的问题,预测剩余油气的分布,提高油田开采的经济效益。在前期3.5维地震勘探方法研究的基础上,对该方法进行了总结和完善,形成了基于参考标准层的井震信息标定、储层构造演化解释、储层沉积演化解释、储层静态建模、油藏开发空间动态信息解释、三维地震信息结合开发静态和动态信息综合解释的一体化工作流程。基于西部某油田开发后期水驱开采实例和东部某油田稠油热采的实例,进一步研究证实了3.5维地震技术的应用性,并提供了最新研究成果。
3.5D seismic is the methodology which integrates high-quality 3D seismic data with the production information of oilfield to solve the problems in reservoir development and find remaining oil during the middle and later development stages of oilfield.This technique integrates seismic,geology,well logging and production information for raising economic benefit in oilfield development.With the earlier study results and the latest research of 3.5D seismic,a reservoir characterization integration workflow was proposed,which includes well-to-seismic calibration based on reference horizon,structure evolution interpretation,depositional evolution interpretation,reservoir static modeling,spatial dynamic production information interpretation, as well as the integrated interpretation of 3D seismic data, static and dynamic information of reservoir production.The application to a water flooding oilfield in west China and thermal recovery for heavy oil in east China indicated the capability of 3.5 D seismic,and provided the latest research achievements.
