陈学义 ,魏斌等 .辽河油田滩海地区低阻油层成因及其精细解释 .测井技术 ,2 0 0 0 ,2 4(1) :5 5～ 5 9应用岩心物理实验和试油结果相结合的方法 ,深入分析低电阻率储层所处的地质环境和形成低电阻率油层的成因。低阻油层的成因是受泥浆侵入、低幅度构造、泥质附加导电等多种影响因素所致 ,但在不同地质条件下 ,只有一种或两种因素对低阻油层的形成起主要作用。利用有效的测井解释方法 ,识别低电阻率油层 ,并在辽河油田锦 2 9井区见到了明显的地质应用效果 。

The geological environment and origin of oil reservoir with low resistivity are analysed in detail on the basis of core analysis and well testing scaling.The conductive reservoir is generated from mud invasion,low height trap and additional shaliness conductivity,etc., but only one or two of which are the dominant factors. Fine interpretation methods are used to identify the conductive reservoir in Block Jin 29 of Liaohe Oilfield. Obvious geological effect has been obtained. A case history shows that the methods are very effective.
