复杂断块油藏精细描述技术——以东营凹陷中央隆起带为例
|
摘要
进入勘探开发成熟期的东营凹陷中央隆起带,具有典型的复式地堑型构造样式,必须应用各种地震地质技术进行精细的油藏描述,才能继续挖掘该地区的生产潜力。通过对复杂断块基本特征的分析,结合典型实例,对其构造、储层、油藏特征等精细油藏描述的具体做法和效果进行了分析和归纳,并着重对构造描述流程、地震地质分析及构造控制下岩性油藏描述等几个方面进行深入研究,提出了复杂断块油藏描述工作的几个方向。
The central uplift of Dongying sag, which has entered mature stage of exploration and development, is a typical complex graben structure. Accurate reservoir description must be conducted by use of various seismic and geological techniques in order to further tap the potential in this area. Combining with typical example, structure and reservoir description has been performed with emphasis on structure description process, seismic and geological analysis, and structure - controlled lithologic reservoir description. Several directions in description of complex fault block with high degree of prospecting are also put forward.
