摘要：
To the problem of being difficult to determine true gas composition of formation for much change of gas composition at early time of gas testing in DS2 well and that at middle and later time, by using well testing interpretation method the paper has concluded that output gas formation is flowing landscape orientation and vertical fluid is not participated through analyzing curve shape of after reciprocal of down hole pressure data. It is thought that the stable gas composition at middle and later time stands for true formation share and it is proved that is correct and creditable through fracture operation.
