无机成因油气领域可能存在比有机油气领域大得多的油气潜量.无机成因油气的成欧条件是:要有岩石圈级深大断裂作通道,以及无机控类运移到地壳表层的过程中不被氧化.根据这些条件和岩石圈结构特征,提出了2种无机成因油气可能成藏的模式;一是在有较厚的还原环境沉积段(在还原环境沉积段中,氧逸度低,无机烃类可以保存不被氧化)的裂谷系或裂陷盆地(这些盆地一般都有与岩石圈底部相通的深大断裂)内的有关圈闭中成藏,往往与有机油气混合成藏;二是在与裂陷盆地相邻共生的隆起区内,水平破裂带(地壳深部烃类的储集体)隆升后的残留体(是理想的裂隙圈闭).在此基础上,指出了无机油气的有利远景区以及勘查无机油气领域的方法.
Inorganic genesis There may be a much larger hydrocarbon potential in the field of hydrocarbons than organic hydrocarbons. Inorganic genesis Oil and gas conditions for the formation of Europe is: there must be lithospheric deep faults as a channel, and inorganic control class transport to the surface of the earth’s crust is not oxidized. According to these conditions and lithospheric structural features, two models of possible hydrocarbon accumulation in inorganic genesis are proposed. One is that in the sedimentary section of thickening environment (in the depositional environment of reducing environment, the oxygen fugacity is low and inorganic hydrocarbons can be Preservation of not oxidized) Rift system or rifting basin (these basins generally have a large fracture with the bottom of the lithosphere) within the trap of accumulation, often mixed with organic hydrocarbon accumulation; Second, with In the uplifted adjacent symbiotic rifting basin, remnants of the horizontal rupture zone (reservoirs of deep hydrocarbon in the crust) uplift are ideal fracturing traps. On this basis, the favorable prospect of inorganic oil and gas and the methods of exploration of inorganic oil and gas are pointed out.
