摘要
构造建模是岩性油藏三维地质建模的基础,精准的地层格架模型是储集层相模型和属性模型建立的根本保障。构造的复杂性使得复杂断块油藏构造建模比常规岩性油藏构造建模要复杂得多,构造模型的建立成为复杂断块油藏三维地质建模的重点和难点。结合复杂断块的特征及常规三维地质建模流程,提出适用于复杂断块油藏构造模型建立的"点-线-面-体"四步法构造建模技术,详细阐述了其操作流程,并针对柴达木盆地油砂山油藏,运用该技术建立了符合复杂断块地质构造特征的三维构造模型。
Structural modeling is the foundation of 3-D geological modeling for lithological reservoir. Establishing an accurate stratigraphie framework is the fundamental guarantee for reservoir facies model and attribute model development. The complexity of structure makes the structural modeling for complex fauh-block reservoir more difficult than for traditional lithological reservoir. Combined with the feature of complex fauh-block reservoir and conventional process of 3-D geological modeling, this paper presents Point-Line-Surface-Geometry four- step structural modeling technique and detailed operation procedure. In view of Youshashan reservoir characteristics in Qaidam basin, the 3-D structural model is developed for this complex fauh-bloek reservoir by using the four-step structural modeling technique.
