英文摘要 | Free and sorbed low-to-medium molecular weight thermovaporized hydrocarbons ( The hydrocarbon content obtained from OM concentrates, however, only reflects the sorbed liquid hydrocarbons. HCSorbed,OM = FIDsignal(OMsh0+sh1)/Mass(OM) x TOCOM In these equations, TOCrock is the total organic carbon of the rock sample; TOCOM corresponds to the TOC content of the OM concentrate sample; Mass(rock) is the initial mass of the rock sample; Massom is the initial mass of the OM concentrate sample; FIDsignaL(rock)(Sh0+Sh1) is the flame ionization detection (FID) signal that corresponds to the global surface area under each thermal peak (Sh0 and Sh1) generated by the Rock-Eval FID; FIDsignal(OM)(sh0+sh1) corresponds to the global surface area under each thermal peak (Sh0 and Sh1) measured by the Rock-Eval FID between 100 degrees C and 350 degrees C after the themovaporization of the OM concentrate sample. Free liquid hydrocarbons are finally calculated as the difference between these last two values (HCFree = HCTotal,rock - HCSorbed,OM). This paper illustrates the application of this methodology on rock samples derived from the Vaca Muerta Formation (Argentina). Along the selected vertical profile, the lower rock interval contains approximately 60% of sorbed liquid hydrocarbons, whereas the upper sample contains more than 90% free liquid hydrocarbons. The parameters FreeHC(Sh0) and FreeHC(sh0) (+ sh1) could be used to identify potential producible free liquid hydrocarbons intervals in early exploration campaigns. |
