鄂尔多斯盆地麻黄山西区块宁东2、3井区侏罗系延8油层组三维储集层建模
|
摘要
针对鄂尔多斯盆地麻黄山西区块宁东2、3井区延8油层滚动勘探开发现状和需要,以层序地层学、沉积学、油气地质学和地质统计学等多学科的理论与方法为指导,从沉积微相特征分析和储集层特征等基础地质研究出发,充分利用现有的三维地震、测井、岩心和露头等资料,采用相控建模方法,建立了该地区侏罗系延安组延8油层组三维储集层地质模型。建模结果分析表明,麻黄山西区块延8油层组三维储集层模型与实际砂体展布和物性特征吻合较好,实现了储集层地质特征的定量化和可视化。
A three-dimensional reservoir geological model of this area was established by using scientific facies-constrained stochastic modeling. The study has been carried out based on the present researches about the Jurassic Yan 8 interval in Ningdong 2 and 3 well-block of the western Mahuangshan area in the Ordos Basin, according to the theories of sequence stratigraphy, sedimentology, petroleum geology and geostatistics, starting from basic geologic researches including sedimentary microfacies analysis and reservoir characteristics discussion, making the best use of the data from seismic survey, well logging, core and outcrop.Analyses of the modeling results indicate that the simulated 3-D model accords well with actual sandbody distribution and petrophysics characters which makes quantification and visualization of reservoir geological characters become possible.
