上覆岩层

基本要素包括一套烃源岩、储集层、盖层和上覆岩层，作用是圈闭的形成和油气的生成运移聚集。

The essential elements are source rock , reservoir rock , seal rock and overburden rock , and the processes include trap formation and the generation-migration-accumulation of petroleum .

地壳上部的水平主应力是上覆岩层自重、地壳温度场和板块挤压三种作用的结果。

Horizontal principal stress in the upper crust of China is due to the weight of the overburden rock beds themselves , the crustal temperature field as well as the compression of the plates .

研究把岩石视为多孔介质，从多孔介质的角度出发，重新建立上覆岩层压力、孔隙流体压力、基岩应力之间的关系式，该式包含了岩石作为多孔介质的一个重要参数孔隙度F。

Rock should be regarded as porous media . Based on this , the new equation is derived to include one important parameter of porous media , F.

地层压力体系包括上覆岩层压力（P0）、地层孔隙压力（Pp）、地层破裂压力（FP）和坍塌压力（BP）。

The formation pressure system includes the overburden pressure ( P0 ), formation pore pressure ( Pp ), fracture pressure ( FP ) and breakout pressure ( BP ) .

并且研究了双相介质（水气、油气）孔隙率、流体饱和度和上覆岩层压力变化对反射波AVO的影响。

The paper also studied the effects of porosity , fluid saturation in diphasic medium ( water gas and oil gas ) and change of overburden pressure on reflection wave AVO .

The discontinuous deformation analysis method ( DDA ) was employed to numerically simulate the stress distribution and deformation of rock strata during the excavation in a coal mine .

认为上覆岩层压力（pob）等于流体静压力（pf）和岩石骨架应力（pG）之和，是不严密的，这可以导致许多错误。

Traditional theory considered that the overburden pressure ( pob ) is the sum of hydrostatic pressure ( pf ) and framework stress ( pG ), this may resulted in many mistakes .
