阿拉新气田地质特征及储层动态研究

Geological characteristics and reservoir dynamic research of Alaxin gasfield

阿拉新气田是大庆中浅层疏松砂岩气藏的重要区块之一。随着开发方案的实施,经过对气田进行精细的地质描述、动态分析以及试井评价等综合研究,进一步搞清了区块的地质特征,并重新核算了地质储量,相对于开发初期提交的探明储量,有所减少。论述了阿拉新气田地质精细研究成果,并结合动态方法,更加明确了各小层的特点以及下一步的开发建议,为今后的气田开发工作提供了借鉴经验。

Alaxin gasfield is one of important blocks with middle-shallow loose sandstones in Daqing oilfield. With the implementation of the development plan, through comprehensive study such as fine geological description, dynamic analysis and well test evaluation, the geological characteristics of the block have been further clarified, and then the geological reserves have been recalculated. Compared with the proven reserves submitted in the early development stage, however, it has decreased. In this paper, the geological fine research achievements have been discussed. Combined with dynamic methods, the characteristics of small layers and development suggestions have been further confirmed, which can provide guidance for future gasfield development.
