The capacity of oil pressure relief and the conversion factor between oil pressure and gas pressure are measured.

测定了油压与气压间的变换系数和油压释放量。

Relief valve or vent valves permit a small pressure to be maintained on the vapor over the oil in the tank (except when the tank is being emptied).

卸压阀或通气阀使罐内油面上方的蒸汽保持微正压(油罐正在排空时除外)。

Relief well is a more mature technology, However, this high pressure for the Gulf of Mexico oil and gas Wells, Small effective, and long construction period.

减压井是较成熟技术，但用于墨西哥海湾这样的高压油气井，收效甚微，且施工周期过长。

And following the intersection of the well bore with those relief wells, they will put heavy mud down there to suppress the pressure of the oil coming up from the reservoir, put a cement plug in and effectively do what I would call a bottom kill, as opposed to the top kill, which was not successful a couple of weeks ago.
