gas-pressure compaction的意思|示意

The clastic rock shallow gas layer has the characters of lower deep and infirmness compaction, so that the compaction extent of mud and the pressure of pore volume and liquid are low.

碎屑岩浅气层具有储层埋深浅，岩体弱压实的特征，故其间泥质的压实程度低，孔隙空间及所含流体承受的压力较小。

The major causes of abnormally high pressure oil-gas pools are hydrocarbon generation, under compaction, montmorillonite dehydration, hydrothermal-pressure increasing and sealing.

烃类生成、压实作用，蒙脱石脱水，水热增压及地层的封闭性是产生高压油气藏的主要原因。

Research on inclusions and mudstone compaction curves shows that uncompaction and structural compression are the main factors resulting in abnormal high pressure in Early Cretaceous gas reservoirs.

前人认为超压的形成主要受控于构造挤压作用 ，此外还有高压天然气的注入、构造抬升等因素 ，基本不存在欠压实作用。
