摘要

欠压实带是因地层具异常高压形成的

但这并不能完全代表现今欠压实带就一定为高压(超压)带

因为古高压(超压)在地质历史中

可能因诸多原因己释放。因此

在确定欠压实带是否仍存在高(超)压时

须视同一剖面砂、泥岩的测井曲线而定

若二者反映的同一层段都存在欠压实现象

则表明现今仍为高压(超压)带;若不一致

则说明古高压(超压)己释放。塔里木盆地以此方法判识的高压(超压)带与测试结果一致。山西沁水盆地QC

井依此判断

其 3个欠压实带现今均为常压段。

Abstract

Uncompacted belts were formed by abnormal high formation pressure.But this does not mean that all the present uncompacted belts are now still high pressure or superpressure belts.It has to be decided by the log of the sandstone and mudstone of the same section.If the log of the sandstone and mudstone indicates the existence of uncompaction in the same interval

it is certain that the uncompacted belt is still a high or superpressure belt;otherwise

the uncompacted belt is not high or superpressure belt.This method was used in Tarim and Qinshui Basins

the results are satisfactory.
