| 摘 要： | 对吉林油田长深井区火成岩低孔低渗型储层取岩芯样品进行应力敏感性测试,样品的渗透率恢复率不超过11%,呈现极强的应力敏感性。通过储层岩芯观察及其他地区火成岩应力敏感性分析结果对比,认为火成岩储层应力敏感性与储层的岩性、结构、构造和孔隙、裂缝发育程度以及发育类型有关。与砂岩较单一的成岩作用不同,火成岩复杂的成岩作用导致不同...

| Abstract: | The core samples of igneous rock formations with low permeability and low porosity in Jilin Changshen well block are tested for their pressure sensitivity.The result shows that permeability recovery rate of these samples is not more than 11%,which indicates high pressure sensitivity of the formations.By observing core samples and comparing the result of pressure sensitivity tests with those from igneous rock core samples of other regions,it shows that the pressure sensitivity of igneous rock formations is r... |
