摘要
低电阻率油气储集层是油气层电阻率与邻近水层电阻率反差较小的油气储层。对已知低阻油藏的岩性特征、物性特征、电性特征以及含油气性和成岩作用对低阻储层的影响进行全面研究,分析了SN油田的低阻储层的成因和机理与识别方法,建立了解释图版和识别标准。利用研究成果对该区域类似油藏进行老井复查和验证,取得了较好的效果。
Oil and gas reservoir with low electrical resistivity is a kind of oil and gas reservoir , of which resistivity difference between oil and gas layer ,and adjacent water layer is smaller .Based on the comprehensive study of influencing factors including lithology ,physical property ,electrical characteristics ,oil-gas possibility and diagenesis ,it was analyzed that the cause and mechanism ,understanding and recognition of low resistivity reservoir in SN oilfield .Thus corresponding interpretation chart and recognition standards were established .The research results were applied to reexamine and verify old wells of similar reservoirs in the area .And good results were achieved .
