TESTING DEVICE AND METHOD FOR MEASURING OIL, GAS AND WATER CONTENTS IN ROCK

A testing device for measuring oil, gas and water contents in a rock, comprising: a thermal desorption unit (400), comprising a sample chamber (105) used for placing a rock sample (106) under test, a crushing mechanism provided in the sample chamber (105), and a heating mechanism (121), wherein the thermal desorption unit (400) can perform closed crushing and heating on the rock sample (106) to achieve gas analysis and desorption analysis of contained oil and water, so that components to be measured are obtained; a cold trap collection unit (110) communicated with the sample chamber (105) and used for trapping oil and water in the components to be measured and performing separation to obtain primarily separated components to be measured; a light hydrocarbon trapping unit (113) communicated with the cold trap collection unit (110) and used for trapping light hydrocarbons in said primarily separated components and performing separation to obtain secondarily separated components to be measured; a gas metering un
