- 摘要:
- 复杂断块油藏以断层配置关系复杂为典型特征，如何精准定量表征储层是目前地质建模的重点与难点。以北大港油田复杂断块油藏为例，充分利用地震、地质、测井、钻井、岩心等资料，多成果融合、多条件协同建立高精度储层模型。提出“分级分步”构造模型建立思路，简单快速地解决复杂断块油藏断层多且复杂等构造建模难题。分析网格系统对地质体的准确刻画与合理表达。采取“多维协同、相序约束”储层属性模型建立法，达到相控、物性参数优相关目的。同时对“甜点”区重点解剖，应用不同随机模拟方法嵌套使用建立储层构型级别模型，准确描述储层内部非均质性。运用以上技术手段可以在提高模型精度条件下，减少储层不确定性，为此类型油田开发部署提供客观、科学的高精度地质模型。
Complex configuration relationship is a typical characteristic in complex fault-block reservoir and accurate and quantitative description of such reservoir is important and difficult in geological modeling. In Northern Dagang Oilfield complex fault-block reservoir development, fully used are such information of earthquake, geology, logging, drilling, core, etc. to establish high precision reservoir model by multiple achievements fusion and multiple conditions collaboration. By means of "Level-control, Step-simulate" structure modeling rule, effectively solved is the complex fault-block reservoir modeling problem. Analyzed is grid system to describe geologic body accurately. Applied is the "Multi-dimensional Cooperation, Facies Sequence Constraints Simulation" to build property model to achieve the purposes of phased-array and better relative physical parameters. Strengthened is study on the "sweet spot" areas, used are different stochastic simulation methods to establish reservoir architecture level model and characterize inner reservoir heterogeneity accurately. These technological means can not only improve the accuracy of the model, but also reduce reservoir uncertainty, which will provide an objective and scientific precision geological model for similar oilfield development.
