摘    要:海上油田水源研究,尤其是地层水回注方面的研究日趋引起关注。渤东低凸起为渤海油田重要产区,注入水源充足与否直接决定着油田开发生产是否顺利。针对该凸起,对主要水源目的层馆陶组进行了水资源量评价研究工作。馆陶组储层系统研究表明,馆陶组砂岩分布广、厚度大、物性好,主要属于中—高孔、中—高渗型储层。采用容积法对渤东低凸起馆陶组储层水资源量进行了计算,目的层水资源总量达1 271×108m3,其中Ng1水资源量达311×108m3,Ng3水资源量达960×108m3,水资源量非常充沛,结合该区水源井产能预测结果,认为馆陶组储层能够满足该区域油田长期开发对水资源的需求。

关 键 词:渤东低凸起  馆陶组  砂岩  储层  水资源量

Abstract:The research on water resource of offshore oilfield, especially on stratum water reinjection, is attracting more and more attention. Bodong low salient is an important oil&gas production area in Bohai oilfield, and whether or not there is enough water injection will have direct impact on the smooth production of oilfield. Against the salient, this paper made evaluation and research on the water resource of Guantao formation which was the target layer of water resource. Research on the reservoir system of Guantao formation indicated that its sand rock, characterized with wide distribution, big thickness and good physical properties, belonged to medium-high porosity and medium-high permeability reservoir. By using volumetric method, this paper calculated the water resource of Guantao formation and concluded that water resource was abundant including total water resource of 1 271×108 m3, Ng1 water resource of 311×108 m3 and Ng3 water resource of 960×108 m3. Combing water source wells deliverability prediction results of the area, it is considered that Guantao formation can meet water resource demands of the long-term development of the oilfield in the area.
Keywords:Bodong low salient  Guantao formation  sand rock  reservoir  water resource
