一、关于油气生成的两种对应观点 在地质界存在着两种截然对立的油气成因说,一种是有机成因说,一种是无机成因说。 有机说认为,油气是“化石燃料”,即由埋藏于沉积地层中的动、植物或动植物混成物质转变而成。此说最早出现于18世纪60年代,先后有动物说、植物说和腐泥说等。现代有机成因说认为,油气是在近海沉积作用过程中,由无数浮游生物、动植物遗体在长期稳定的还原环境和良好的埋藏条件下经化学降解而成。有机质转化为油气通常经过三个阶段:先是在生物化学作用下形成干酪根和天然气;之后干酪根在
I. Two Corresponding Views on Hydrocarbon Generation There are two diametrically opposed generative causes of hydrocarbons in the geological field. One is the organic genesis and the other is the inorganic genesis. Organic said that oil and gas are “fossil fuels,” that is, by the buried in sedimentary formations of animals, plants or plants and animals mixed material into. This first appeared in the 1860s, there have been animals that plant said and sapropelic said so. The modern organic cause suggests that oil and gas are chemically degraded by innumerable plankton, animal and plant remains under long-term stable reducing environment and good burial conditions in offshore sedimentation. The conversion of organic matter to hydrocarbons usually goes through three stages: first, kerogen and gas are formed by biochemistry; then kerogen
