A new adjustable way was developed first time which use cluster well to decrease drilling cost and increase benefit in deep imbedded, low permeability, high pressure reservoir.

It makes analysis on reducing operating pressure technology for abnormal fracture pressure reservoir, and screens out technical measures for carbonate reservoir fracturing in Tahe peripheral oilfield.

开展了降低异常高破裂压力储层施工压力技术分析，并筛选出适应于塔河外围油田碳酸盐岩储层压裂改造的技术措施。

"The pressure buildup we're seeing is consistent with the modeling we did around reservoir depletion and full integrity," Wells said.

“我们正在看到的压力增加是与我们在油藏枯竭和完全完整周围的模型一致的。”威尔斯说。

So the expansion against lower pressure draws less heat from the hot reservoir right.

所以压强较低时的膨胀,从高温热源吸收的热量更少。

If pressure bleeds off there is clearly a problem with the pressure integrity of the shoe, However, industry practice dictates that a positive test, that is no pressure drop, is not diagnostic, simply because the reservoir pressure is sufficient to retain the pressure being applied.

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.
