Abstract
Condensate critical flowing saturation means the minimum saturation causing condensate flow,i.e.the endpoint of condensate gas phase permeability curve.For a long time past,it has been tested by use of analogue oil and analogue gas owing to the limitation of technological conditions.Real condensate critical flowing saturation is a hot point problem studying abroad at present.For this reason,different results,even contrary ones,have been obtained by different scholars because of considering different quantities of irreducible water in different systems.A method of directly testing the condensate critical flowing saturation by ultrosonic wave under flowing conditions in core at high pressure and high temperature was first proposed and two constant-volume depletion critical flowing saturations of real multi-component condensate gas were measured in artificial cores by the authors.According to the measure results of the two condensate gas samples in the artificial cores,it is obtained that the condensate criticle flowing saturation are 15% and 18% respectively,which opens up a new way for the application of ultrosonic wave in laboratorial core flowing testing.关键词
