While the fluid flows up along relative close and wider rift system (not blowout to surface) under overpressure, its nature is close to pressure conduit flow in fluid mechanics,which could be described by Bernoulli equation.

Experimental study on the effects of compaction on the properties of sandstone reservoir;

The main diagenesis includes compaction,cementation,dissolution,replacement and recrystaUization.

The compaction is the main force that expels the hydrocarbon from source rocks in Fulin subsag.

The geological facts of the regional unconformity,the evolution of Mesozoic-Cenozoic fault and basin in the area show that there are five compression deformations in Mesozoic-Cenozoic period.

The Mesozoic faults,regional unconformities and basin evolution in the Yanshan area suggest that there occurred not only strong compression but also strong extension in the Yanshanian Stage.

There are many kinds of structure-fluid interactions in nature, among which the pressure solution, the fluid-induced cracking, and the crack closing are the most important ones during the geological processes.
