Abstract

Abstract

On the basis of the results of hydropyrolysis simulations for about 90 different types immature to mature source rocks selected from about 5 000 marine source rocks in China, and accompanied by the investigation on the natural thermal evolution profiles, it was suggested that, the content of total organic carbon (TOC) of excellent marine source rocks does not change obviously at immature stage R_o < 0.8%, or at high-post mature stage R_o > 1.3%, and the residual TOC content decreases gradually with the maturity increase during the immature to low mature stage. The maximum of the decrease of the residual TOC content for sapropel (Ⅰ), Ⅱ₁ and Ⅱ₂ type kerogen from excellent source rocks is usually 40%, 32% and 24%, and the TOC restitution coefficient is 1.68, 1.48, 1.32, respectively. Both the amplitude and the restitution coefficient of TOC decrease gradually with the decrease of TOC content for the source rocks with low organic matter abundance (0.3 % < TOC < 1.0%), and the TOC restitution coefficient is 1.20 when 0.3% < TOC < 0.5%, and close to 1.0 when TOC < 0.3%. The TOC content of solid bitumen and shale with high organic matter abundance (TOC > 30%) also required no restitution at high mature stage. The decrease of S₁+S₂ of marine source rocks (0.3% < TOC < 30%) and the increase of the hydrocarbon quantity generated and expulsed in laboratory simulation are consistent with the decrease of the residual TOC content observed in natural thermal evolution profiles.
