Formation Pore Pressure的意思|示意

The pore pressure also strongly influences the state of stress in a formation (by as much as 50%) and is therefore a critical piece of information for designing hydraulic fracturing treatments.

孔隙压力也强烈地影响地层中的(多达50%)的应力状态，并针对设计水力压裂处理而言是一项重要信息。

Formation drillability is related to formation compact degree and pore fracture degree, so NDR can reflect formation pore pressure state.

地层可钻性与地层的压实程度和孔隙破裂程度有关，因此NDR可以反映地层孔隙压力的情况。

Due to the higher thermal expansion of fluid in low permeability shale, the super pore pressure may lead to the development of effective tensile stress and even formation fracturing.

由于低渗透页岩地层流体高温膨胀导致的超孔隙压力，有可能产生有效拉张应力，严重时会导致地层破裂。

Pore pressure is the pressure of the fluid in the formation.

孔隙压力是地层中液体的压力。

Gas reservoir in Xujiahe Section 2 in west Sichuan are low porosity, low permeability, deep, high formation pore and fracture pressure, etc.

川西须家河组2段气藏属于低渗低孔致密深层气藏，地层压力和破裂压力高。

The lower the permeability and the smaller the pore-throat radius as well as the lower the reservoir pressure, the easier the formation of water locking damage, and it is difficult to be removed.

渗透率越低，孔喉半径越小，油层压力越低，越容易产生水锁损害，且越难以解除其损害。
