Abstract

Abstract: The hydrous pyrolysis simulation test for coal samples of Middle-Lower Jurassic in Tuha basin is conducted. The PVT phase state of hydrocarbon-generated products is quantitatively calculated by PR state equation in different temperatures. The analysis shows that the oil phase of hydrocarbon generation has turned into the gas phase of it, and the vitrinite reflectance (R_o) ranges from 1.2% to 1.6%, as the simulated temperature rises.

Key words: Tuha basin, Jurassic, coal, thermal simulating test, phase state
