The Hydrocarbon Generation and Exploration Prospect of Yanji Depression
Yanji Depression was formed on the base of Upper Paleozoic strata.Distribution area of Carboniferous-Permian strata is about 1550km2, and the strata are preserved intact.By researching on the thermal evolution analysis of hydrocarbon source rock and the source-reservoir-cap combination, the hydrocarbon generation and exploration prospect was studied.The results show that the thickness and the depth of Carboniferous-Permian strata are great, and organic matter maturity is on the stage of high mature-past mature, and it has two stages of hydrocarbon generation process, and the residual hydrocarbon generation potential is low.Upper Paleozoic, Mesozoic and Cenozoic have extensive sandstone reservoir, and have favorable territorial cap rock.It forms two types of source-reservoir cap assemblage, and has great Hydrocarbon Resource Potential.After analysis the unconventional oil and gas, it shows that Yanji depression has the formation condition of tight sandstone gas and shale gas.
