THERMAL SIMULATION EXPERIMENTAL RESEARCH ON COAL-BEARING SOURCE ROCKS IN XINWEN AREA

The capsule-type closure system was adopted and it was very important that thermal simulation experiment analysis of hydrocarbon source rocks and the characteristics of coal-bearing source rocks of permian conducted hydrocarbon production. The experiment shows that coal measure hydrocarbon source rock has good hydrocarbon potential on Carboniferous,the yield of gaseous hydrocarbons varies with temperature change.Hydrocarbon phase was divided into two forms, that is, the continuous hydrocarbon generation and secondary hydrocarbon generation. Continuous procession of hydrocarbon gas drying coefficient was less than the secondary hydrocarbon generation. From500℃ to 550℃, both dryness became consistent, mainly generate methane. The more phenomena of secondary hydrocarbon generation there are, the less the total gas production will be.
