reservoir pressure

基本解釋

The rule of reservoir pressure distribution and bottom hole flowing pressure alteration of a periodic trial-produce well in infinity subterranean formation.
無限大地層中—口間歇試采生產井的地層壓力分布及井底流壓變化規(guī)律；
Inn most oilfields reservoir pressure decline and increased volumes of water produced with the oil give rise to conditions where the wells will not flow unaided.
在大多數(shù)油田，油藏壓力下降，伴隨著油產出的水的體積上升，導致了井沒有幫助就不能流動的情況。
Reservoir pressure decline, the increase of recovery rate and the damage of rock structure are main reasons of micro fine migration and sand production during oil recovery process of such reservoirs.
疏松砂巖油藏開采過程中，油層壓力下降和采油速度的增加以及巖石結構的破壞，是造成油層巖石微細粒運移和油井出砂的主要原因。

So the expansion against lower pressure draws less heat from the hot reservoir right.
所以壓強較低時的膨脹,從高溫熱源吸收的熱量更少。

They decline significantly from one year to the next because each barrel of oil taken from a reservoir reduces the pressure within the field, leaving less force available to push the next barrel of oil up the well.

The air was held in a reservoir and when the pressure reached 100 PSI, a modified irrigation valve was triggered to launch a tennis ball that had been stuffed down the barrel.

Still, the reservoir behind the dam was emptied to relieve pressure on the structure, the state-sponsored Chinese business news magazine Caijing reported.

地層壓力
In one hand,the oil/water gravitational differentiation is utilized to raise the oil/water interface and increase the oil recovering volume. In the other hand,water is injected to supplement the reservoir energy and restore the reservoir pressure.
一方面利用油水重力分異,抬升油水界面,增加采出量;另一方面注水補充地層能量,恢復地層壓力。

The overall water resistance experiment of LD-19 seals of II type shows, when the gate’s gap is within 30mm, and the reservoir pressure is under 2.0MPa, if the back pressure is large enough, the seal could resist the water.
