低渗透岩心随温度升高,孔隙度会不断降低,在胶结物含量高的情况下也许会存在相反的结果,其主要原因可能是由于胶结物在高温条件下出现了脱水现象导致了岩心孔隙度升高,在高温条件下岩心中的胶结物对岩心孔隙度有着很大的作用;对于渗透率,实验表明随着温度的升高岩心渗透率不断变大,随着围压的增大岩心渗透率降低。 The porosity of low-permeability cores decreases with increasing temperature. The opposite may result when the content of cements is high. The main reason may be that the dehydration of cement under high temperature leads to the porosity of cores , The cement in the core under high temperature has a great effect on the core porosity. For the permeability, the experiment shows that the core permeability increases with the increase of the temperature, and the core infiltration increases with the confining pressure Lower rates.
