摘要

高邮凹陷戴南组高导泥岩的高导特性

主要是由泥岩盐度差异引起的

与化学成分和粘土矿物关系不大.高导泥岩沉积时

不是一个简单的湖水不断扩大

而是一个扩大、缩小、再扩大、再缩小的过程

水深、水介质性质亦随之相应变化.反映了在构造背景稳定条件下

气候和地表迳流注入量的控制作用.

Abstract

The high conductivity of high conductive mudstone is mainly caused by sali-nity difference

and has less relation with the chemical composition and claymineral of mudstones.The deposition of the mudstone is not a simpleprocess of the lake enlargement

but a process of enlarging-contracting andreenlarg-recontracting.In the meantime

the depth of water and the nature ofmediums were changed correspondingly.This shows the control actions of ancientclimate and direct runoff under the stable structural background.
