Abstract:

Use data of bottom pressure restoration of well with right angle coordinate system to draw P-T curve,and then chose two time-points(t1,t23) from the average value,read out corresponding P1,P2 and P3 value,produce time curve slope and productivity index on the basis of the plate.Interval between each point shall be chosen as following rule;interval between t1 and t2 shall not be too small,40mm for t1 and 300mm for t2.The establishment of this method is mainly on the basis of theory of slug flow test.Predicative results got from an oil field in eastern China by this method are almost as same as practical testing results.

Key words: non flowing well, slug flowing test, productivity, application
