|
摘要
复杂断块油藏的精确定量表征是目前储层地质建模技术发展的难点和研究热点。文中以枣园油田枣北构造孔一段枣Ⅱ油组复杂断块油藏地质建模为例,充分利用已有的地质研究、测井解释、地震解释等成果,以RMS软件为依托,将软件特有的建模技术手段与基础地质研究相结合,针对构造模拟、微相模拟及属性模拟中的难点提出了相应的研究对策,准确合理地将地质认识转化为约束条件,并综合应用多种方法对各阶段模型进行验证,有效解决了复杂构造、强非均质性储层建模的难点,提高了复杂断块油藏随机模拟精度,使所建模型接近地下地质实际,为该区下一步数值模拟研究和目标挖潜提供了可靠的地质依据。
At present,the accurate and quantitative characterization of complex fault-block reservoir is the difficulty and research hotspot for reservoir geological modeling.In this paper,taking the geological modeling of complex fault-block reservoir for ZⅡoil group of Kong 1 Member in Zaobei Area,Zaoyuan Oilfield as an example,based on the data such as geological research,log and seismic interpretation,using RMS software and combining the modeling technique of RMS with basic geological research,the corresponding research countermeasures are put forward according to the difficulties of structure modeling,micro-facies modeling and attribute modeling.Based on the methods,it turns the geology understanding into constraint condition accurately.It also uses many ways to check and correct the model to make sure that the model is according with the underground geological conditions.The difficulties of reservoir modeling are resolved effectively.The stochastic modeling precision of complex fault-block reservoir is improved.The model can provides reliable geology basis for the further numerical modeling and the exploration of potential target in study area.
