昆北油田切16区E1+2油藏出水类型及原因分析
Water Production Types and the Reason for E1+2 Reservoir in Qie 16 Well Block, Kunbei Oilfield
摘要
Abstract
The increasing water production and moisture content has constrained the daily output significantly in Qie 16 well block of Kunbei Oilfield,which has seriously affected the economic and effective development of theoilfield.Based on structure,reservoir,logging,test data and test curves,this study analyses the watering characteristics and its reason in the area.The study shows that there are many kinds of water types in the area,and can be divided into layer internal water,interlayer water,edge water and injected water.The watering types are different in different stages and the production curves possess different characteristics.In the early test production stage,layer internal water dominates,and the watering types increase to become mixed water when the injection is performed.The distribution of watering types are simple for only the layer internal water is widely distributed and the other three types are relatively limited.As different watering types are controlled by different factors,this paper only analyses in detail the reasons for the layer internal water.The result shows that this kind of water is controlled by reservoir physical property,oil saturation and oil viscosity.关键词
