Based on the method offinite element, the numerical method of calculating single well formation pressure under the condition of dense well pattern quasi-steady was established. Considered the formation pressure field before well off test, numerical well testing theory under the condition of dense well pattern was established. The influence of well spacing, injection-production ratio,drainage area shape and parameters of reservoir bed on numerical well test curve was analyzed. Analysis method of well test for dense well pattern was determined, which could fix the theoretical foundation for calculation of formation pressure and well test interpretation under the condition of dense well pattern.
