| 摘 要： | 本文以渤海湾油区南部含油气盆地为例,讨论了地温对盆地生油、砂岩孔隙性和特殊油、气藏形成的地质作用和意义。地热研究不仅限于学科自身的范围,而且已向石油、天然气等流体矿藏的成藏领域突入,并从已知的深层原生天然气藏、高含二氧化碳的天然气藏、特高压油藏和特稠油油藏的成藏实例中,找到了某些结合点。

| Abstract: | Based on the study of Weibei basin, Dongying and Huimin basins in southern Bohai
Bay petroleum province, this paper discusses the effects of geotemperature on the
hydrocarbon's generation, migration and accumulation. The author believes that high
temperature not only decreases the depth of oil- window, but also lets poor organic matter
into kerogen produce high waxy crude oil. Through the core analysis of well X. 38, the au-
thor obtains the result for the first time that the slightly metamorphism of source rocks
caused by the high temperature of volcanic rock bodies led the original organic matter to be
remained. On the other hand, high geotemperature can change the porosity of sandstone
reservoirs and also can lead the formation of various special oil and gas pools in various
tectonic position of a basin, including primary gas pools, high carbon dioxide gas pools,
abnormally high pressure oil pools and very heavy oil pools etc. |
