Gas formation Gas reservoir的意思|示意

On the basis of the theory of petroleum system, t he geochemical mode of gas reservoir formation in Carboniferous in East Sichuan Basin was studied by applying gas reservoir geochemical methods.

本文根据含油气系统理论，采用气藏地球化学方法，研究了四川盆地东部石炭系天然气成藏的地球化学模式。

During the process of condensate gas reservoir development, the gas-liquid two phases have formed due to the appearance of condensate oil along with the decrease of formation pressure.

在凝析气藏的开发过程中，随着地层压力的不断下降，在地层中凝析出凝析油，形成气、液两相。

For gas Drilling, the bottom hole pressure is far smaller than the formation pressure, so that the gas in the reservoir come out to the hole continuously and get out of the well.

当用气体钻井打开储层时，由于钻进时井筒流动压力远远低于地层孔隙压力，储层流体就不断地流入井筒，并返出到地面。

For volumetric gas reservoir, gas well absolute open flow (AOF) is reduced with the decrease of formation pressure.

对于定容气藏，气井的绝对无阻流量随地层压力的下降而降低。

In gas and condensate gas reservoir, the content of the irreducible water has great importance to the calculation of reserve and the percolation of formation fluid.

气藏及凝析气藏中，束缚水含量对气藏储量计算、流体渗流有重要影响。

The formation mechanism of gas is analyzed in the paper, the majority of gas derives reservoir oil degradation gas, the minority derives the biogenic methane in Jurassic coal stratum .

分析了该天然气的成因，指出它主要是来自储层原油的菌解，另外还有侏罗系浅部煤系地层生物气的贡献。
