Abstract:

The Repeat Formation Testor (hereinafter referred to as RFT) was introduced into our country from overseas markets at the end of 70 s and early in 80 s. Since then RFT data have been widely used by quite a few oil fields from day to day,and it is obvious that more thoroughgoing, perfect and precise explanations for these data are undoubtedly required.
Referring to some related articles published by both domestic and foreign specialists in recent years, this paper mainly introduces the application of RFT data to the cvaluation of oil (gas) reservoirs based on the principle of RFT as well as the basic theory for data explanations.The emphasis is placed on the introduction to the explanation of RFT data，the error analysis and the new method of rectification for measured formation pressures.In this way，we may define fluid properties and various fiuid contacts within reservoirs both recisely and reliably in order to provide a powerful scientific basis for distinguishing oil(gas) reservoir types and calculating their reserves.

Key words: RFT data, Oil-gas reservoir, Measured formation pressures, Error analysis, The new method of rectification
