【Abstract】 In[WT5”,6BZ] order to find out dynamic performance of each zone within perforations of a production well and dynamic performance ofeach small zone within a thick oil formation interval, a multizone well tester and a multi-Sample sampling device have beendeveloped. The multizone well tester, through a hydraulic device, controls set and release of upper and lower pokers and sizeof test chamber, forming a very small formation production production einvironment in the test chamber, a quartz crystal gauge is used todetect its pressure changes. After completion of one zone test, the hydraulic device pushes a piston to discharge test chamberfluid and release upper and lower packers, and then it is ready for next zone test. The multi-sample sampling device has several Sample chambers, one trip of tool may obtain several samples. The multizone well testing technique is able to acquire dynamic information near wellbore such as static formation pressure, permeability, skin factor and fluid type, productivity etc.,which would provide reliable basis for zonal production and injection, production rate increment, water control and tertiary recovery etc.更多还原
