RFT资料的误差校正及应用

自我国于七十年代末、八十年代初从国外引进电缆地层重复测试仪(简称RFT)后,近几年以来,RFT资料在油田上的应用越来越广泛,对RFT资料的解释也要求日趋深入、完善、精确。本文主要参考了近年来国内外专家、学者发表的有关文章,结合海上一个新发现的油田实际资料,从RFT仪器原理、资料解释的理论基础出发,介绍了RFT资料在油(气)藏评价中的应用,着重介绍了RFT资料解释,对地层压力测量值进行误差分析和校正的新方法,以便更精确可靠地确定油田内流体性质和不同流体界面,为判断油(气)藏类型、计算油气储量提供有力依据。

APPLICATION OF RFT DATA AND ERROR RECTIFICATION

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.
