To ascertain how to produce differential pressure reasonably during the course of high temperature and pressure gas well testing, we must consider synthetically the following situations : both liquid in well bore and solid phase particles of mud in strata can be carried out through airflow ; we must avoid sand production out of borehole walls and make the selected differential pressure meet the demands of the testing instrument capability ; the calculation of differential pressure when no sand comes out of strata covers the calculation of strength of rock of borehole walls and airflow velocity, etc
