【摘要】：地球化學(xué)指標(biāo)是烴源巖及非常規(guī)頁巖儲(chǔ)層研究的重要參數(shù),該類型參數(shù)對烴源巖的生烴潛力評估及儲(chǔ)層有效性評價(jià)均具有重要意義。采用Passey經(jīng)典公式計(jì)算濟(jì)陽坳陷沾化凹陷渤南洼陷沙三下亞段(E s_3)湖相泥頁巖地層總有機(jī)碳含量(TOC)時(shí)誤差較大,通過重新分析TOC與測井響應(yīng)之間的關(guān)系,發(fā)現(xiàn)TOC與三孔隙度曲線的相關(guān)性較好。在此基礎(chǔ)上,先分巖性(油泥巖、泥巖和油頁巖)建立TOC計(jì)算模型,計(jì)算精度得到明顯提高;再根據(jù)TOC和深度(D)間接建立熱解烴(S_2)、氫指數(shù)(HI)及最高裂解溫度(T_(max))等參數(shù)的計(jì)算模型,利用解釋出的連續(xù)HI,T_(max)及TOC等數(shù)據(jù),定量評價(jià)干酪根類型及有機(jī)質(zhì)豐度;最終結(jié)合由測井資料計(jì)算而得到的礦物組分、物性參數(shù)等信息,有效地識別出地層剖面中富含的Ⅰ型和Ⅱ1型有機(jī)質(zhì)泥頁巖巖相。該研究成果為濟(jì)陽坳陷沾化凹陷渤南洼陷沙三下亞段湖相泥頁巖有利儲(chǔ)層預(yù)測提供了理論基礎(chǔ)。
[Abstract]:Geochemical index is an important parameter in the study of source rock and unconventional shale reservoir. This type of parameter is of great significance for hydrocarbon generation potential assessment and reservoir effectiveness evaluation of source rocks. Using Passey's classical formula to calculate the total organic properties of the lacustrine shale shale strata in the lower member of the third lower section of the Bonan sag in Zhanhua depression, Jiyang depression. The error of carbon content is larger than that of TOC. By re-analyzing the relationship between TOC and logging response, it is found that the correlation between TOC and three-porosity curve is good. On the basis of this, the TOC calculation model is established by dividing lithology (mudstone, mudstone and oil shale), and the calculation accuracy is improved obviously. Based on TOC and depth D), the calculation models of pyrolytic hydrocarbon S2H, H _ 2 index and maximum pyrolysis temperature (T _ T _ (max)) were established. The data of continuous Hippon _ T _ (max)) and TOC were used to quantitatively evaluate the kerogen type and the abundance of organic matter. Finally, combined with the information of mineral components, physical properties and other parameters calculated from logging data, The mudstone facies of type 鈪，
