摘要
油藏注水开采过程中,详细了解注采见效状况及井间连通性,对指导注水开发全过程,延长稳产时间,提高采收率等都具有重要的作用。本文用相关系数理论,通过相关度的大小来判断油田注水见效情况及井间连通性,取得了很好的效果。研究表明Spearman秩相关系数能分析注水见效及井间连通性,本文的研究对油田开发具有重要的指导意义。
In the process of petroleum reservoir water flooding,comprehension of the effective response to water flood and inter-well connectivity in detail is of great help for guiding the whole process of water injection development,extending the stable production time and improving the EOR.In this paper,the effective response to water flood and inter-well connectivity is judged through the value of the relevance by the theory of correlation coefficient,and very good results have been achieved. The research demonstrates that Spearman rank correlation coefficient can analyze effective response to water flood and inter-well connectivity,the research in the paper has important guidances for the development of oilfield
