复杂断块油藏精细描述技术研究与应用——以大港油田第三系地层为例
|
摘要
复杂断块油藏是大港油区分布最广的油藏类型。论述了复杂断块精细油藏描述在构造研究、河道砂体预测、剩余油研究等方面形成的油藏描述技术及具体方法。研究认为,处于开发中后期的复杂断块老油田精细油藏描述研究工作的重点在于以井震结合、动静结合、多学科综合研究为基础,开展层次约束多重控制的地层对比、井震动静结合的构造精细解释、单一河道及内部构型刻画、多方法剩余油分布研究等方面,应突出精细化和全面化的特点,进一步深挖老油田剩余油潜力,以提高开发水平。
The complex fault-block reservoir is the most widely distributed in Dagang Oilfield. The reservoir description techniques, which are formed from the complex fault-block fine reservoir description on the structure research, channel sand body prediction, residual oil research and so on, are discussed. The result show that in the middle and later periods of the complex fault-block development in the old oilfield, the fine reservoir description research works are focused on a combination of well and seismic, combination of dynamic and static state, the multidisciplinary comprehensive research. The stratigraphic correlation of hierarchy level constraint and multiple controls, the fine structure interpretation of the well and seismic combination with dynamic and static state, the description of the single channel and inside configuration, residual oil research with multiple means, etc. are developed. To improve the level of development, the refinement and the characteristics of comprehensive are should be highlighted and further research for the residual oil potential of the old oilfield.
