| Abstract: | Injection/pressune drawdown method is one kind of single well transient pressure testing. Injection rate and pressure are the key factors in the test design. The calculation method for normal parameter,surface equipment and pipeline structure for open hole well and cased well were given in the paper. The construction step and its advantage and shortcoming were also introduced. |
