陕北三叠纪煤田勘探中油页岩的地球物理测井效果

油页岩是一种重要的潜在能源,储量巨大,若折算成发热量,它的储量在化石燃料中仅次于煤而列第二位;若折算成页岩油,世界上油页岩储量约为4750亿t,相当于目前世界天然原油探明可采储量的5.4倍,因此油页岩的勘探与开发已成为世界性新能源开发的课题。本文针对综合地球物理测井曲线在油页岩上具体的反映特征进行了系统论述,对以后的勘探与开发利用具有重要意义。

GEOPHYSICAL LOGGING OF OIL SHALE IN EXPLORATION OF THE TRIASSIC COAL-FIELDS IN NORTHERN SHAANXI

Oil shale is an important potential energy,which has huge reserves.If converting it into calorific capacity,the reserves would be ranked the second in fossil fuel in China,just following coal.If converting it into shale oil,the reserves of oil shale in the world is about 475 billion tons,almost 5 to 4 times of minable reserves of native oil in the world.Therefore,exploration and development of oil shale is a task for development of new energy resources.This paper has made a systematic discussion of the practical reflections on oil shale resulted from synthetic geophysical logging curves,which would be significant to exploration and developemt of oil shale in future.
