【摘要】：應(yīng)用地質(zhì)、地球化學(xué)、測(cè)井、地震反演、沉積相和構(gòu)造埋深等資料,預(yù)測(cè)烴源巖厚度、有機(jī)質(zhì)豐度和有機(jī)質(zhì)類型等的平面分布,采用生烴潛力方法建立風(fēng)城組烴源巖的生排烴模式,評(píng)價(jià)風(fēng)城組致密油的資源潛力。結(jié)果表明:風(fēng)城組烴源巖分布面積廣、厚度大、有機(jī)質(zhì)豐度高,有機(jī)質(zhì)類型以Ⅱ型為主,目前處于低成熟—成熟演化階段。風(fēng)城組烴源巖在鏡質(zhì)體反射率Ro為0.5%和0.85%時(shí)分別達(dá)到生烴門(mén)限和排烴門(mén)限。風(fēng)城組烴源巖現(xiàn)今累積生烴量為3.185×10~9 t,累積排烴量為1.531×10~9 t,殘留烴量為1.654×10~9 t,其中云質(zhì)巖致密油與頁(yè)巖油資源量分別為0.613×10~9 t和1.565×10~9 t。綜合分析認(rèn)為,風(fēng)城組烴源巖類型好、生排烴量大,為晚期排烴,具有廣闊的致密油勘探前景。
[Abstract]:Using geological, geochemical, logging, seismic inversion, sedimentary facies and structural buried depth data, the plane distribution of source rock thickness, organic matter abundance and organic matter types are predicted.The hydrocarbon generation and expulsion model of source rock of Fengcheng formation was established by using the method of hydrocarbon generation potential, and the resource potential of dense oil in Fengcheng formation was evaluated.The results show that the source rocks of Fengcheng formation have wide distribution area, large thickness, high abundance of organic matter, and the type of organic matter is mainly type 鈪，
