Description | Isomerizations of methyldibenzothiophene from Neogene mudstones in northeast Japan were examined as a maturity parameter of organic matter during the diagenesis to catagenesis stage.The relationship between methyldibenzothiophene(MDBT)ratio(MDR:4-MDBT/1-MDBT)and vitrinite reflectance(Ro)from the Tojo TS-1 well,which underwent subsidence at low heating rate,can be described by the equation:MDR=15.1 Ro-5.35(n=11,r=0.85,Ro=0.4-0.7%).This equation is similar to that from Elmworth 6-28-68-13 W 6 M in Western Canada.New combination of the 1-MDBT,(2- + 3-)MDBT and 4-MDBT isoomers are used to be a new maturity parameter which is useful in the high maturity stage,up to 3% Ro.The ratio(2- + 3-)MDBT to(1- + 2- + 3- + 4-)MDBT increases from 0.2 to 0.6 over the range 0.4-3.0% Ro.The ratio(2- + 3-)MDBT to 4-MDBT was constant at about 0.5 in the range 0.4-1.5% Ro,and then increases from 0.5 to 4.5 in the range 1.5-2.9% Ro.Therefore,the(2- + 3-)/(1- + 2- + 3- + 4-)MDBT ratio is possibly on effective maturity indicator through the oil generation stage to higher maturity stages such as the dry gas zone.After the catagenesis stage,(2- + 3-)/(4-)MDBT ratio and high Ro gradients could assist interpretation of scattered(2- + 3-)/(1- + 2- + 3- + 4-)MDBT ratios with low gradient.
