Geological Study of the Yan'an Formation in the Northeastern Oil Region of Zhaizi River
Currently,the oil-rich region in the northeast of Zhaizi river boasts extensive reservoirs within the Yan'an formation,with significant initial trial extraction results.However,due to insufficient understanding of the geology of the Yan'an formation,targeted water injection development has proven challenging.To address this issue,theoretical frameworks such as petrology and stratigraphy are employed,utilizing diverse data sources to intricately delineate sub-layers within the oil reservoir.A comprehensive analysis of the current development status in the oil region has been conducted,delving deeply into identified issues.The proposed development adjustment and deployment strategy,taking into account both geological and economic benefits,aims to not only increase reservoir utilization but also realize a larger scope of recoverable reserves.This approach ensures the maximization of project benefits,creating favorable conditions for the successful operation and sustainable development of the entire project.Ultimately,it establishes a solid foundation for future oilfield development,paving the way for a robust and sustainable future.
