RESEARCH AND APPLICATION OF METHOD FOR EVALUATING WELL STIMULATION

This paper introduces the method for evaluating well stimulation.The type decline curves,including exponential,hyperbolic and harmonic delines,are used to match production of oil well,and then determine decline tendency of oil well stimulated.Based on this,oil increase productivity can be calculated.It is a objective method for calculating oil production increment of well stimulation,and can be used to evaluate correctly the effectiveness of well stimulation.
