摘要
文中简要介绍了碳氧比能谱测井的原理、分析孔隙度、矿化度、岩性、原油密度和井眼对其测量的影响因素和适用范围,提出碳氧比能谱测井资料处理解释存在不足之处,进而通过分析大量的碳氧比能谱测井资料解释存在的问题。以碳氧比能谱资料及岩心分析资料为基础,建立了准确可行的解释模型。该模型在大港油田5个地区的综合应用,在老井挖潜、准确判断油层水淹、油—水界面和油层动用状况上取得了好的效果,值得推广和应用。
The paper introduces the principle of carbon/oxygen(C/O) spectral logging,analyzes the influences of porosity,salinity,lithology,crude density and wellbore on measurement as well as its applicable ranges,and demonstrates the deficiency of data processing interpretation in carbon/oxygen(C/O) spectral logging.Based on carbon/oxygen(C/O) spectral logging data and core analysis,an accurate and feasible interpretation model is established,which applies to 5 regions in Dagang oil field.It is demonstrated that the model obtained good results in making full use of veteran oil wells,correctly determining water-out oil layers,oil/water interface and producing reserves.This model is worth spreading and applying.
