THE RAPID PRODUCTION TESTING TECHNOLOGY USING CONVENTIONAL DOWNHOLE TOOLS

In order to improve the current situation of tesing technology,To reduce further costs,to shorten the period,and to increase the economic benefits,the conventional production testing technology has been reformed since the April,1992 in the 2th Production Department of Jiangsu Oilfield.According to the different well conditions,two kind(three sets) of practical units are designed for rapid production test,which consist of the piezometric tube,packer,screen pipe,uniflow valve,pressurizing drip etc.,whose advantages are reliable Performance,strong applicability and easy to operate and so on.The success rate of 93 Percent is obtained in the field tests of 7 layers,the problem that the wellbore fluids entry the oil bed is resolved and the expected results are reached.This paper introduces the structure,theory and testing results of the said units,and gives suggestions for the improvement.
