| 摘 要： | 中国的大多数气藏属于低渗气藏。低渗气藏与油藏相比 ,具有不同的渗流特点 ,其评价需要采用能模拟气藏特点的实验方法。目前 ,国内外尚无针对气藏损害特点的实验及评价方法。在对低渗气藏应力敏感性进行研究的基础上 ,提出了模拟气藏特点的储层应力敏感性实验和评价方法。

| Abstract: | Among the gas reservoirs found so far in China, most are low permeability reservoirs. The formation damage mechanism of these reservoirs is very different from that of the medium or high permeability reservoirs. So, it is necessary to evaluate the formation damage of low permeability reservoirs with a standard other than that of conventional oil or gas reservoirs. Based on a series of the research results of stress sensitivity for low permeability gas sands, a new evaluating standard for stress sensitivity damage to low permeability gas sands is developed. |
