Abstract:

Compared with the log plate interpretation,there is low accuracy in water quality interpretation chart and circulating rate of umbrella formation interval tester.To the log plate interpretation of umbrella formation interval tester in fluid profile of production log,there are more error in the interpretation of water content.In this paper,on the basis of interpretation and appreciation of plate and judgment on the bore hole fluid property and qualitative description in the pressure testing data of fluid profile,a new underground rod pumped well explanation is submitted.The method based on the successive approximation method in chart.By applying the interpretation theory of spondylolisthesis model,a correction on water holdup,water content and slippage velocity can be made.And by using the interpretation of down hole scale，the total flow rate and water content in the interpretation zone can be obtained.By comparing the interpretation of down hole scale with the plate method,the previous is more accurate in fact.

Key words: rod pumped well, fluid production profile, down hole calibration method, interpretive plate method, production logging interpretation
