本文選題：東營(yíng)組 + 烴源巖評(píng)價(jià)　； 參考：《大慶石油地質(zhì)與開(kāi)發(fā)》2017年03期

【摘要】：為了有效評(píng)價(jià)東三段烴源巖并明確其油源貢獻(xiàn),以大量的鉆井、地球化學(xué)以及油氣勘探資料為基礎(chǔ),基于烴源巖評(píng)價(jià)的特征參數(shù)及油源對(duì)比方法,探討了東營(yíng)組烴源巖特征及烴源巖對(duì)油氣成藏貢獻(xiàn)。研究結(jié)果表明:東營(yíng)組有效烴源巖主要發(fā)育于東三段,其w(TOC)平均為1.1%~1.2%,最高可達(dá)7.8%以上,為好烴源巖,有機(jī)質(zhì)類型以Ⅱ型為主,成藏期(距今2 Ma)R_o值為0.7%~0.9%,處于大量生油高峰,最厚的有效烴源巖位于林雀洼陷與柳南洼陷,其次為曹妃甸洼陷;與沙一段和沙三段相比,東三段典型的生物標(biāo)志化合物特征為Pr/Ph值高以及伽馬蠟烷/C_(31)霍烷值低,以此可較好地與沙一段和沙三段烴源巖進(jìn)行區(qū)分。油源對(duì)比結(jié)果表明,現(xiàn)存的東營(yíng)組烴源巖貢獻(xiàn)的原油主要呈環(huán)狀分布于柳南洼陷以及林雀洼陷附近,曹妃甸洼陷附近仍有較大勘探潛力。
[Abstract]:In order to effectively evaluate the source rocks of the third member of the eastern region and determine their oil source contribution, based on a large amount of drilling, geochemistry and oil and gas exploration data, based on the characteristic parameters of source rock evaluation and the method of oil source correlation,The characteristics of source rocks in Dongying formation and their contribution to hydrocarbon accumulation are discussed.The results show that the effective source rocks of Dongying formation are mainly developed in the third member of Dongying formation, and the average value of the source rocks is 1.1% and 1.2%, with the highest value of 7.8%. The source rocks are good source rocks. The type of organic matter is mainly type 鈪，
