枣园油田油藏精细描述技术与方法

在查明油田构造、沉积体系、储集体几何形态和储层参数的空间分布规律,确定油藏类型及油气储量,阐明油气控制因素及油气富集、高产区分布规律的基础上,为编制、调整开发方案,提供了完整的符合地下情况的全套数据和地质依据,还提出适合枣园油田特殊非均质油藏的描述及综合评价技术,并综合构造、沉积、储层成岩后生作用的研究,对储层渗流屏障、渗流差异、敏感性及孔隙渗流等方面的研究,提出并形成了油藏渗流地质学新观点,为枣园油田和同类油藏的勘探开发,提供了理论基础.

THE TECHNOLOGY AND METHODS OF RESERVOIR DESCRIPTION IN ZAOYUAN OILFIELD

On the basis of specifying the structures of oilfield,sedimentary systems,geometryshapes of reservoir hodies and spatial distribution of reservoir parameters,the types of oilreservoir and the reserves,of oil-gas are determined,the control factors of oil-gas and thedistributions of abundant oil zones are indicated,the development plans are made and adjusted,a set of data and geological conditions corresponed to subsurface groundback are present.The technology of characterization and comprehensive evaluation of special heterogeneousreservoir in Zaoyuan Oilfield are also available.Two new viewpoints are present in this paper.One is about petrophysical fscird which is based on the cornprehensive study of structure,sediment and diagenetic lategeneration of reservoir,The other is about reservoir flow geologywhich is developed aceordingt to flow barrier,flow difference,sensibility flnd pore flow.Theseviewpoints lay theoretic fundamentation for the exploration and development of Zaoyuan oil-field and the same type of oilfields.
