Abstract:

According to the organic geochemical and petrological analyses on Triassic mudstones from Well MS 1,the organic matter abundance, type and maturity are revealed. And the hydrocarbon generative potential is addressed
and evaluated. The results show that the organic matter abundance is between 0.17%~9.11% and the average value is 1.62%, reaching the standard of high-quality source rock. The organic matter are mainly derived from higher plant, the kerogen type is from II2 to III. The organic matter has gone into mature stage. Thus, the Triassic mud-stones are favorable for hydrocarbon(especially gas)generation. Considering that the source rock potential of the Triassic strata has not been well constrained, this study provides a new reference information for regional oil and gas exploration nationally and internationally.

Key words: Triassic, hydrocarbon generative potential, Junggar Basin, Well Moshen 1, organic geochemistry
