The paper put forward the idea of sampling for gas hydrates by hole bottom freezing, and the method is that the temperature of the gas hydrate core is decreased on the hole bottom by cold source, the result of decreasing the temperature is the same as increasing pressure to inhibit gas hydrate dissociating and retains the core of gas hydrates. Firstly, the feasibility of hole bottom freezing method...
W artykule zaprezentowano aparaturę do badań in-situ średniej wartości przewodnictwa cieplnego i oporu cieplnego skał w otworach. Umożliwia ona nowe podejście do oceny parametrów skał i gruntów dla potrzeb projektowania systemów pomp ciepła (GSHPS). Stwierdzono między innymi, iż średnia wartość przewodnictwa cieplnego zmierzona w reżimie iniekcji ciepła jest wyższa od tejże, określonej w reżimie poboru...
