【摘要】：為弄清留楚地區(qū)斷裂控藏規(guī)律,在明確油源斷裂的基礎(chǔ)上,采用斷面埋深等值線法刻畫出油源斷裂優(yōu)勢(shì)運(yùn)移通道,結(jié)合烴源巖供烴能力和油氣分布特征,分析了斷面優(yōu)勢(shì)運(yùn)移通道有效性的差異及其對(duì)油成藏分布的控制作用。結(jié)果表明,留楚地區(qū)油源斷裂為明化鎮(zhèn)組沉積末期活動(dòng)的Ⅲ型、Ⅴ型和Ⅵ型斷裂,凸面型斷面為其優(yōu)勢(shì)運(yùn)移通道;斷面優(yōu)勢(shì)運(yùn)移通道有效性按照其溝通烴源巖級(jí)別的不同分為有效、較有效和低效3個(gè)等級(jí);斷面優(yōu)勢(shì)運(yùn)移通道的分布控制了油氣的平面和縱向分布,斷面優(yōu)勢(shì)運(yùn)移通道有效性等級(jí)控制了油氣的富集程度。研究成果對(duì)留楚地區(qū)下一步勘探具有重要指導(dǎo)意義。
[Abstract]:In order to make clear the rules of fault and reservoir control in Liuchu area, on the basis of clear understanding of oil source faults, the dominant migration channels of oil source faults are described by using the section buried depth isoline method, and the hydrocarbon supplying ability and hydrocarbon distribution characteristics of source rocks are combined. The difference in the effectiveness of the dominant migration channel and its controlling effect on the distribution of oil accumulation are analyzed. The results show that the oil-source faults in Liuchu area are 鈪，
