摘要
达尔其油田沉积物源近,沉积厚度薄,岩性物性变化快,非均质性强,导致腾格尔组储层发育低阻油层,通过综合分析低阻油气层常规电测井响应特征,总结了一套适合本地区的测井识别方法,如双电法、视地层水电阻率法、自然电位减小系数法等,在所研究区块都取得了明显的效果。
Because of close to the sedimentary source,thin sedimentary thickness,quick lithology and physical properties changes and strong heterogeneities in Daerqi oilfield,the reservoir in tengge＇er formation developed low-resistivity oil layer.Through a comprehensive analysis of conventional electrical logging response characteristics of low resistivity reservoirs,a set of logging identification methods suitable for the local region,such as double- electrical resistivity method,apparent formation water resistivity method,spontaneous potential coefficient reducing method,is summed up. They have taken obvious effect in the study block.
