Study on inferring interwell connectivity of injection-production system based on decision tree
摘要
Abstract
The traditional method of identifying interwell connectivity of injection-production system is manual analysing the logging curve by every small layer,which is labor-intensive,bring out a lot of workload and keep a very low work efficiency.In order to change the status quo of inferring interwell connectivity in Daqing oilfield,this paper analysised the logging data of oilfield development to extract and establish some relative characteristics between injection wells and production wells and used CART algorithm to construct a decision tree for the automatic identification of interwell connectivity of injection wells and production wells.According to the experimental results,this method has the advantages of simple operation and fast discriminant.It improves the efficiency of discrimination and meanwhile ensured a greater accuracy.关键词
