Abstract

Niniejszy wynalazek dostarcza urządzenie do badania szybkości desorpcji gazu dla zagęszczonej skały, które utworzone jest z urządzenia do desorpcji (101) gazu, urządzenia do pomiaru objętości gazu (102) i komputera (18), przy czym urządzenie do desorpcji gazu zawiera uchwyt rdzenia, pompę wspomagającą i manometr; urządzenie do pomiaru objętości gazu zawiera zbiornik gazu, gumowy wąż, miernik masy, specjalny płyn, zbiornik płynu i cienkie folie, zbiornik gazu mieści specjalny płyn i zbiornik płynu mieści specjalny płyn; gdy uchwyt rdzenia wytwarza ciśnienie w przestrzeni pierścieniowej, gaz w próbce skały ulega desorpcji, wypływa przez zawór do zbiornika gazu, w którym gaz może wypierać specjalny płyn do zbiornika płynu; miernik masy mierzy masę wypieranego specjalnego płynu i przesyła tę informację do komputera po linii transmisji danych w czasie rzeczywistym, a komputer rejestruje masę specjalnego płynu wypieranego w czasie rzeczywistym, a w przypadku, gdy znana jest gęstość specjalnego płynu, komputer automatycznie oblicza objętość specjalnego płynu wypieranego w czasie rzeczywistym, oraz komputer oblicza szybkość desorpcji dla próbki skały na podstawie objętości specjalnego płynu wypieranego w czasie rzeczywistym.The present invention provides a device for testing the gas desorption rate for compacted rock, which is formed of a gas desorption device (101), a gas volume measuring device (102) and a computer (18), the gas desorption device comprising a core holder, a pump booster and pressure gauge; the gas volume measuring device includes a gas tank, rubber hose, mass meter, special fluid, fluid tank and thin films, the gas tank holds a special fluid and the fluid tank holds a special fluid; when the core holder creates pressure in the annular space, the gas in the rock sample is desorbed, flows through the valve into the gas tank, in which the gas can displace special fluid into the fluid tank; the mass meter measures the mass of the displaced special fluid and sends this information to the computer in a real-time data transmission line, and the computer records the mass of the displaced special fluid in real time, and if the density of the special fluid is known, the computer automatically calculates the volume of the special displaced fluid real-time, and the computer calculates the desorption rate for a rock sample based on the volume of special fluid displaced in real time.
