【摘要】 高角度断裂控油新模式与碳沥青成矿有着相似的成藏模式,只是缺少后阶段高热演化导致的碳沥青成矿。高角度断裂中油气成藏经历了烃源岩成岩——油气形成(储层)——运移储集三个阶段。断裂浅表的液态原油受到氧化等多种稠化机制作用而固态化(沥青化)使断裂产生自然封闭,有利于液态原油的进一步富集成藏。高角度断裂控油新模式,是传统圈闭成藏模式的一种补充。实际上,两者既是不同的成藏模式,又具有油气成藏储、盖、阻的共同特征。更多还原

【Abstract】 The new model for controlling oil with high-angle faults is similar to that of carbon asphalt mineralization, but lacks of carbon asphalt mineralization caused by high heat evolution in the later stage. Oil and gas accumulation in high angle faults has experienced three stages: source rock diagenesis-oil and gas formation( reservoir)-migration and accumulation. The liquid crude oil on the superficial surface of the fracture is oxidized and solidified( asphalted) by various thickening mechanisms, which makes the fracture naturally closed and is beneficial to the further enrichment and accumulation of liquid crude oil. The new oil control model of high angle fault is a supplement to the traditional trap formation model. In fact, they are not only different reservoir-forming modes, but also have the common characteristics of oil and gas reservoir-forming, cap-forming and block-forming.更多还原
