There are some problems about back pressure testing data when the deliverability test data is processed in Hetianhe gas field of Tarim basin, test production sequence changes leads to a certain errors to be in results of the analysis. The influence of production sequence to back pressure well test is analyzed on the basis of binomial deliverability formula, four error formulae for production system are given. Combined with field examples, it is recognized that increasing sequence has the smaller error. And increasing geometric factor between productions as far as possible, widening the gap between productions that will help to reduce errors, which provides a basis for the back pressure well test design. ©, 2015, Well Testing.
