精细地震解释技术在海上某油田开发前期研究中的应用
|
摘要
海上油田开发前期决定了平台位置以及油田后续开发的潜力,是油田生命历程中的一个特殊阶段,精细地震解释技术在该阶段发挥着重要作用。为此,组织了系列攻关研究,总结出包括井震精细标定、精细地层格架建立、储层预测以及砂体描述技术等在内的一系列精细地震解释技术。在中国海上某油田开发前期研究中充分应用了该系列技术,对该油田油藏类型、油水关系、沉积微相以及砂体非均质性等方面进行了深入研究,提出了馆陶组油藏类型新认识,建立了精细地层格架、刻画了沉积相特征及储层非均质性,为油田原有的油水关系矛盾提供了合理解释。后续开发生产情况表明,其系列成果符合该油田地质情况。
Pre-development is a special stage for an offshore oilfield,which decides the location of platform and the following devel opment potential of the oilfield.In this stage,fine seismic interpretation technology may play a significant role.Therefore,a lot of targeted researches were carried out,and a series of fine seismic interpretation technologies were developed,including well-to-seismic fine calibration,fine stratigraphic framework establishment,reservoir prediction and sand description.These tech nologies were then used in the pre-development researches of some oilfield,and the researches covered the aspects of reservoir types,the relationship between oil and water,sedimentary microfacies,sandbody heterogeneity and so on.The researches brought new recognition of the reservoir types in Guantao formation,established fine stratigraphic framework and depicted sedimentary fa cies and reservoir heterogeneity,providing reasonable interpretation for the initial contradiction between oil and water of oilfields.The latter development and production situation proved that the series of researches fruits accorded with the geological conditions of the oilfield.
