An evaluation method of reservoir development effectiveness by using individual well deliverability sequence

There are some defaults on the existing system of evaluating effectiveness of reservoir development for its unitary index and fussy manipulation.A new method was proposed to evaluate reservoir development effectiveness.Based on Pateto's law,a series of individual well deliverability sequence over the years of a reservoir can be established,and the development effectiveness can be analyzed qualitatively and evaluated quantitatively by means of the correlation between the degree of reserve recovery and the change rate of deliverability size which was derived from the linear regression of individual well deliverability sequence.The application results show that not only does the individual well deliverability sequence denote the distribution rule of the individual well deliverability,but also characterize the development potential and effectiveness quantitatively.The principle of this method for evaluating effectiveness of reservoir development is different from that of reservoir engineering method and can be an enrichment to present evaluation system of reservoir development.
