【摘要】：经过多年的研究对临江地区扶余油层有一定的认识,但是,由于临江地区扶余油层主要为岩性-构造复合油气藏,识别评价难度很大,目前对岩性-构造复合油气藏的预测精度还不能满足勘探布署的要求。为了解决扶余油层勘探布署的问题,就要解决有效储层的预测问题。本文以临江地区扶余油层为例,通过在临江地区扶余油层开展地震、地质结合的构造特征研究,沉积微相分析,精细储层预测研究,对储集层属性进行描述,结合储层的构造格架运用相关软件,建立三维储层地质模型,通过模拟出的临江地区地下地层沉积模型,能更加客观、全面的展示出地下构造、储层特征,能更有效的进行储层预测。储层地质模型的建立可以直接为油田开发、管理、开发方案调整提供服务。同时,通过三维储层地质模型分析储集层的空间展布特征,探索并解决生产布署中扶余油层有效储层无法准确预测、储集层与成藏匹配不好,虽有较好的砂岩却无法形成油藏的难题,对油田开发中指导井位布署以及如何提高勘探经济效益都有很大的帮助。
[Abstract]:After many years of research, there is a certain understanding of Fuyu reservoir in Linjiang area. However, because the Fuyu reservoir in Linjiang area is mainly composed of lithologic and structural reservoirs, it is very difficult to identify and evaluate Fuyu reservoir. At present, the prediction accuracy of lithologic and structural composite reservoirs can not meet the requirements of exploration and deployment. In order to solve the problem of exploration and deployment of Fuyu reservoir, it is necessary to solve the problem of effective reservoir prediction. In this paper, the Fuyu reservoir in Linjiang area is taken as an example. Through the research on structural characteristics of seismic and geological combination, sedimentary microfacies analysis and fine reservoir prediction in Fuyu oil reservoir in Linjiang area, the properties of reservoir are described, and the relevant software is used in combination with the structural framework of reservoir. By establishing a three-dimensional reservoir geological model and simulating the sedimentary model of underground strata in Linjiang area, the underground structure and reservoir characteristics can be displayed more objectively and comprehensively. The establishment of reservoir geological model can directly provide service for oil field development, management and development scheme adjustment. At the same time, the spatial distribution characteristics of reservoir are analyzed through three-dimensional reservoir geological model. To explore and solve the problem that the effective reservoir of Fuyu reservoir in production layout can not be accurately predicted, the reservoir is not well matched with the reservoir formation, although there is good sandstone, it cannot form the reservoir. It is of great help to guide well location arrangement in oilfield development and how to improve the economic efficiency of exploration.
