LOSS RECOVERY, CORRECTION AND PYROLYSIS APPARATUS, METHOD, AND SYSTEM FOR LIGHT HYDROCARBONS IN MUD SHALE

WIPO Patent Application WO/2024/016628

A1

A loss recovery, correction and pyrolysis apparatus, method, and system for light hydrocarbons in a mud shale. The apparatus comprises: a pyrolysis tank (2) capable of containing and heating a full-diameter core sample (8), two opposite ends of the pyrolysis tank (2) being respectively provided with an input pipeline (21) and an output pipeline (22), and the output pipeline (22) being provided with a diverting assembly (3) and forming a first branch pipeline (221) and a second branch pipeline (222); a carrier gas assembly (1) communicated with the input pipeline (21); and a detection assembly (4) comprising a first detection unit (41) and a second detection unit (42) which are respectively used for quantitative detection and qualitative detection, the first detection unit (41) and the second detection unit (42) being respectively connected to the first branch pipeline (221) and the second branch pipeline (222). Full-diameter core pyrolytic analysis can be carried out on site, the problem of light hydrocarbon loss caused by rock fragmentation is effectively avoided, and quantitative and qualitative analysis of light hydrocarbon pyrolysis can be achieved by means of quantitative diversion of high-temperature gas.
