摘　　要：针对鄂尔多斯姬塬油田长6段低阻油藏油水层识别难度大，通过对其低阻油层特征及成因进行了细致的分析，运用“四性”关系法、微分分析法、曲线形态相关分析法、组合熵识别法等手段，定性识别油、水层应用该技术对姬塬油田12口探、评井长6段进行了二次解释，应用效果良好，对姬塬油田长6段油藏勘探开发具有一定指导意义。In view of the big difficulties in identifying oil-water reservoirs of low resistivity Chang6 reservoirs in Jiyuan Oilfield, Ordos Basin, oil and water reservoirs are qualitatively identified in the paper through detailed analysis of the characteristics and genesis of the low ,＇esistivity reservoirs, and by means of the ＂four-property＂ relationship, differential analysis, curve shape correlation analysis, and combination entroy recognition method. Applic, ation of the technology re-interprets the Chang6 intervals in 12 exploratory and/or appraisal wells of the Jiyuan Oilfield, with good results.
