Based on transient well test theory,the feasibility and reliability of deriving formation pressure by dual flow rate test technique are analyzed,the application range of this test technique is discussed.

Raster sensor and its application in the flow test;

The technology of no-flow-concentrating flow testing in water injection well is based on principle of interpolation of super sonic wave transfer which has a feature of being test without flow-concentration,without setting up the flow-concentration and of conducting test in many formations at once time and preventing the influence on test from temperature,viscosity,residue and turbulent flow.

According to the use of stabilized mixing plant of WBS-300 type for many years, the article presents that flow test is used to control the mix proportion of stabilized soil and then to further guarantee the mixing quality of mixture.

According to testing requirement,test traffic should be similar to practical network traffic.

This paper analyzes the problem of stochastic test traffic generating,concludes the generating expressions of stochastic test traffic.

This paper presents a generating technology of self-similar test traffic.

Accurate reservoir pressure and other data can be obtained from two-flow well test which doesn\'t need to shut in the tested well but need to flow it twice with different rates.
