崖城13-1气田构造模型和流动单元层模型的建立
|
摘要
崖城13-1构造是一个半背斜构造,构造的形成与基底隆起有关。崖城13-1气田是中国近海在开发的最大的气田,陵水组三段储层是其主要的储气层。陵水组和崖城组在构造顶部被剥蚀,对于陵三段气层来说其构造形态是一个“秃顶”的半背斜。利用储层顶底精细的深度构造图建立起了气田的构造模型;利用高分辨率层序地层学把陵三段储层划分为7个流动单元,根据井点流动单元分层数据和地层模式建立了流动单元层模型。上述工作为崖城13-1气田的地质统计学三维储层建模打下了很好的基础。
Yacheng 13-1 structure is a half-anticline. The form of the structure is relation to the basement apophysis. Yacheng 13-1 gas field is the largest gas field on Chinese offshore, which is developed by CNOOC. Its main reservoir is the third segment, Lingshui formation. At the structure top, the rock of Lingshui and Yacheng formation was denudated. As for the gas reservoir of Lingshui formation, its structure configuration is a "bared" half-anticline. The structure model was built based on the fine depth structure maps of the top and bottom of the reservoir. The reservoir of Lingshui formation was divided as 7 flow units. The flow unit layer models were built based on the wells data and the stratum mode. Those research productions were indispensable to building 3-D reservoir model of Yacheng 13-1 gas field by Geostatistics.
