| 摘 要： | 低渗气层压力敏感性是钻井过程中造成气层损害的主要因素之一。采用来自胜利油田的岩样作为代表低渗气层的标准岩样,进行了气层压力敏感性的试验研究。试验表明,气层压力敏感效应的强弱决定于压力敏感声、的大小,气层存在明显的压力滞后现象,另外,气层内部含水饱和度越高,气层的压力敏感效应越强。

EXPERIMENTAL STUDY ON PRESSURE SENSITIVENESS OF CONGLOMERATED GAS RESERVOIR WITH LOW PERMEABILITY |
| |
| Abstract: | The pressure sensitiveness of gas reservoir with low permeability is one of main factors resulting in gas formation damage during drilling. The experimental study was done for the pressure sensitiveness of gas reservoir, by using the rock samples from Shengli Oilfield as standard samples of gas reservoir with low permeability. The experiment indicates that the pressure sensitiveness depends on the size of pressure sensitive point. Pressure delay is found obviously in the gas reservoir. In addition, the pressure sensitiveness of gas reservoir is greater the higher water saturation. |
