Abstract:There are the functional relations among the flow parameters of air in the air reverse circulation drilling piplie, including volume of flow, velocity of flow, pressure and pressure difference which have a great effect on carrying solid phase. It is of significance of quidance to test movement parameters, find their regularity and study movement mechanism of air carrying solid phase during the reverse circulation drilling. The test items and purpose are introduced and the test results are analyzed in this paper.
keywords:reverse circulation dirlling, medium, solid phase, volume of air, lifting velocity, pressure difference
