摘要: 在分析异常孔隙流体压力形成条件及机制的基础上,建立了一套利用声波时差资料计算目前欠压实泥岩异常孔隙流体压力的方法和一套古异常孔隙流体压力的恢复方法。通过分析异常孔隙流体压,力形成与演化历史,建立了异常孔隙流体形成时期和终止时期的确定方法。该方法在松辽盆地北部青山口组泥岩中的应用结果表明,它用于系统研究欠压实泥岩异常孔隙流体压力是可行的。

Abstract: Based on the analysis of the condition and mechanism for forming abnormal pore fluid pressure in undercompacted mudstone, two methods for calculating current abnormal pore fluid pressure and for buildup of the ancient abnormal pore fluid pressure of undercompacted mudstone by acoustic transit time are developed in this paper. Also, an approach for determination of the formation period and end period of abnormal pore fluid pressure is presented, which applied results in Qingshankou mudstone of northern part of Songliao basin show that it is practical for systematic study of abnormal pore fluid pressure in under compacted mud- stone.

Key words: compaction, mudstone, abnormal pressure, Songliao basin
