Study On Production Rule And Injection-production Connectivity Of Well 530 In Badaowan Formation Of Karamay Oilfield

This paper takes reservoir 530 of badaowan formation in karamay oilfield as the research object.Taking sedimentary microfacies as the main classification standard,it was divided into two sedimentary facies with great difference in physical properties,namely channel and heart beach,and then studied the production rules of different sedimentary facies by types.Based on different sedimentary facies,this paper systematically studied the development characteristics and rules of well 530 of badaowan formation reservoir,including the rising law of water cut,production decline curve and water drive characteristic curve,as well as the characterization types of interconnectivity between injection-production Wells.The methods of statistics and reservoir numerical simulation are used.The results show that the above laws are obviously different in different sedimentary facies.The rising curve of water cut is obviously different from that of channel.Based on the analysis of the field production dynamic data,it is divided into four rising types.The type of production decline on the heart bank is exponential decline,and the type on the channel is hyperbolic decline.The water drive characteristic curves of a and b are compared with the chart drawn by colleagues.It is found that according to the current development mode,the recoverable reserves predicted by water drive curve type b are close to the characteristics of actual production.The connection between injection-production Wells is divided,and the static and dynamic identification criteria are established.It provides theoretical support for the adjustment of the later scheme.The production rules and injection-production connectivity studied in this paper have a good reference to the development of conglomerate reservoirs similar to the badaowan formation.
