【摘要】：為了研究斷裂在下生上儲(chǔ)式油氣成藏中的作用,在油源斷裂優(yōu)勢(shì)通道輸導(dǎo)油氣能力影響研究的基礎(chǔ)上,利用油源斷裂優(yōu)勢(shì)通道本身的發(fā)育特征和源巖品質(zhì),構(gòu)建了油源斷裂優(yōu)勢(shì)通道輸導(dǎo)油氣能力綜合評(píng)價(jià)參數(shù)指標(biāo),建立了一套油源斷裂優(yōu)勢(shì)通道輸導(dǎo)油氣能力綜合評(píng)價(jià)方法,并將其應(yīng)用于渤海灣盆地冀中坳陷留楚地區(qū)東三段儲(chǔ)層10條主要油源斷裂優(yōu)勢(shì)通道輸導(dǎo)油氣能力的評(píng)價(jià)中。結(jié)果表明,留楚地區(qū)東三段儲(chǔ)層10條主要油源斷裂共34條優(yōu)勢(shì)通道,其中:有8條輸導(dǎo)油氣能力綜合評(píng)價(jià)等級(jí)為強(qiáng),主要分布在北部留楚背斜區(qū);有15條輸導(dǎo)油氣能力綜合評(píng)價(jià)等級(jí)為中等,主要分布在留楚南背斜區(qū);有11條輸導(dǎo)油氣能力綜合評(píng)價(jià)為弱,主要分布在南部和東部邊部地區(qū)。這與目前留楚地區(qū)東三段儲(chǔ)層只在北部留楚背斜核部找到大量油、中部留楚南背斜找到少量油相吻合,表明該方法用于油源斷裂優(yōu)勢(shì)通道輸導(dǎo)油氣能力綜合評(píng)價(jià)是可行的。
[Abstract]:In order to study the role of faults in the formation of oil and gas reservoirs, based on the study of the influence of oil and gas transport capacity on the dominant channel of oil source fault, the development characteristics and source rock quality of the dominant channel of oil source fault are used. The comprehensive evaluation parameter index of oil and gas transportation ability of dominant channel of oil source fault is established, and a set of comprehensive evaluation method of oil and gas transportation ability of dominant channel of oil source fault is established. It is applied to the evaluation of oil and gas transport ability of 10 dominant channels of main oil source faults in the east third member reservoir in Jizhong Depression, Bohai Bay Basin. The results show that there are 34 dominant oil source faults in 10 main oil-source faults in the third member reservoir in Liuchu area. Among them, 8 have strong comprehensive evaluation grade of oil and gas transfer ability, mainly distributed in the northern Liuchu anticline; There are 15 middle grade of comprehensive evaluation of oil and gas transport capacity, mainly distributed in the south of Liuchu anticline, and 11 of which are weak in comprehensive evaluation of oil and gas transport capacity, mainly in the southern and eastern border areas. This is consistent with the large amount of oil only found in the core of the northern Liuchu anticline and a small amount of oil in the central Liuchunan anticline, which indicates that this method is feasible for the comprehensive evaluation of the oil and gas transfer capacity of the dominant channel of oil-source faults.
