| 摘 要： | 根据电性与岩性、矿化度的经验关系,通过对电测深不同极距等视电阻率值平面电性分布特征,综合钻探地质、测井曲线反映的沉积相规律,推断黄河冲积扇的演变,由深到浅,或者说从老到新的规模是由小到大,即面积大约为11800km2→52000km2→66700km2的发展过程。

| Abstract: | Based on the empirical relationship of electrical properties to lithologiccharacters and mineralization intensity and according to the pattern of sedi-mentary facies reflected by plan electrical property distribution characteristicsof equi-apparent resistivities at different polar distances of electrical sounding,integrated drilling-geological data and logging curves, it is inferred that theevolution of the Yellow River alluvial fan from deep to shallow (or from oldto young) is characterized by the gradual increase in size with the areaapproximately from 11800 km2 through 52000 km2 to 66700 km2. |
