摘要(Abstract):
为实现对超低渗透率岩层的真实模拟,克服现有流固耦合相似材料的不足,研发了一种具有超低渗气密性且参数可调的新型气固耦合岩层相似材料.该材料以铁精粉、重晶石粉、石英砂为骨料,特种水泥为黏结剂,水泥添加剂和淀粉为调节剂,采用电动夯实机振动压实成型.选取m_(特种水泥),m_(水泥添加剂),m_(淀粉)作为影响因素,采用正交试验方法测试了材料的力学渗透性质及影响规律,其中,相似材料的气体渗透率利用自主研发的相似材料渗透率测试仪通过稳态法测试.试验结果表明:材料的密度为2.47~2.66 g/cm~3,单轴抗压强度为0.66~8.86 MPa,弹性模量为66.65~438.17 MPa,渗透率为3.71×10~(-3)~4.63 mD,各参数均可通过m_(特种水泥),m_(水泥添加剂),m_(淀粉)进行精确调节;材料干燥快速,性质稳定,渗透率可在1.5 MPa气压下维持恒定.研发的超低渗气密性岩层相似材料可用于煤与瓦斯突出、页岩气开采等气固耦合模型试验中超低渗气密性岩层的模拟.
