Abstract

Due to original sedimentary environments and accumulation processes, oil and gas reservoir are usually of great in-homogeneity. After the later-stage reservoir stimulation measures, the formation property of near-well zone and distant-well zone are often quite different. In order to characterize this kind of reservoir more accurately, the reservoir can be radially treated as composite reservoir with different zones. Based on method of variables separation to solve conventional flow problems, the pressure solution is originally obtained for radially dual composite reservoir by using the same method. This case enlarged the application of variables separation method for solving flow problems in oil and gas reservoir, and these work is also of great significance for evaluation of composite reservoirs.
