【摘要】：四川盆地川西坳陷是印支期以來龍門山擠壓推覆所形成的前陸盆地,中段東坡地區(qū)包含合興場—高廟子、豐谷、永太、中江—回龍和知新場—石泉場共計5個三維地震勘探區(qū)塊,涉及3個構(gòu)造區(qū)帶。通過研究烴源巖生烴演化史并對研究區(qū)6口井22塊流體包裹體樣品進行熒光觀察、顯微測溫、測鹽等系統(tǒng)分析,結(jié)果表明:上三疊統(tǒng)須家河組五段烴源巖于151~145 Ma進入生烴門限,130 Ma達到生烴高峰;研究區(qū)侏羅系沙溪廟組砂巖儲層發(fā)生過3期與油氣成藏有關(guān)的流體活動,分別發(fā)生在距今141~128 Ma(J_3-K_1),105~88 Ma(K_1-K_2),83~68 Ma(K_2),成藏關(guān)鍵時刻主要在烴源巖的生烴高峰期130~68 Ma(K_1-K_2)。
[Abstract]:Sichuan Basin West Sichuan Depression is a Foreland basin formed by the compression and nappe of Longmen Mountain since Indosinian period. The east slope area of the middle section contains Hexingchang-Gaomiaozi, Fenggu, Yongtai, etc. There are five 3D seismic exploration blocks in Zhongjiang Huilong and Zhixinchang-Shi Quan fields involving three tectonic zones. Based on the study of hydrocarbon generation evolution history of source rock and the systematic analysis of 22 fluid inclusion samples from 6 wells in the study area, such as fluorescence observation, microthermometry, salt measurement, etc. The results show that the source rocks of the fifth member of the Xujiahe formation of the Upper Triassic reached the peak of hydrocarbon generation at 151- 145Ma entering the hydrocarbon generation threshold of 130Ma, and the sandstone reservoir of Shaximiao formation of Jurassic system occurred fluid activity related to oil and gas accumulation in three periods in the study area. Respectively, at 141T 128MaS J3-KS / T / 88 / 88 Ma-K1-K _ 2S / T _ 1 / K _ 1-K _ 2S / T _ 1 / T _ 1-K _ 2 / T _ 1 / T _ 1 / T _ 1 / K _ 2 respectively, the key time of reservoir formation is mainly at the peak of hydrocarbon generation of source rocks, 130m ~ 68 Mai K _ 1-K _ 2S _ 2.
