老井测井储层评价与剩余油挖潜研究

STUDY ON RESERVOIR EVALUATION WITH WELL LOGGING AND REMAINING OIL TAPPING POTENTIALAITY IN OLD WELIS

辽河油田勘探开发经历了几十年，已经进入中后期，储层的合油性不断改变，如何有效挖掘剩余油显得越来越重要，本文主要是利用裸眼井中常规测井资料，结合后期套管井中的新测井资料，例如C／O、中子寿命、过套管电阻率等测井新方法来评价储层。采用地层对比法、交会图法、试油结果分析法和油气显示分析法等，在实际应用中取得了较好的效果，本文结合四个实例，给出了储层评价与剩余油挖潜的具体方法。

Liaohe oilfield has a development history of few decades.It has entered into a mid-later period.Remaining oil distribution has changed. How to find remaining oil effectively becomes more and more important.This paper formulates that combination of conventional logging data of a borehole with that of cased hole,such as C/O,neutron life time and through-casing resistivity,etc.,can be used to evaluate reservoirs. Stratigraphic correlation,cross-plot,oil testing result analysis and show of oil and gas analysis have good effect.Thepaper gives out four cases to show the concrete methods of reservoir evaluation for remaining oil tapping potentialaity.
