Abstract: lPR curve is a kind of characteristic curve descrbing the basis reiationship between oil well production and bot-tomhole flowing pressure.Using dimentionless lPR curve and dimentionless general equation IPR, the evaluation methods of pay zone cantamination are studied in this paper.Practical application indjicated that it is a simple and ease methoxi.

Key words: pay zone contamination, lPR equation, satura1ed reservoir, unsaturated reservoit
