【摘要】 本文通过对中坝须二、雷三凝析气藏形成条件的研究,表明成熟期的陆源成因油气、不同源的腐泥与腐植型油气混合的混源型油气在一定条件下也能形成凝析气藏,其形成、富集的地质因素是有利于凝析油气体系成生的有机相带,适合凝析气藏形成的温压条件及圈闭、运移、储集条件的时空配置。更多还原

【Abstract】 By studying formation conditions of Zhongba gas fields in Xu-2. Lei-3 condensate gas reservoirs, this paper shows that in the matvre period, continental-source-origin Oil and gas, Sapropelic and humic type of oil and gas of dfferent sources, and mixed source type of oil and gas can also form condensate gas reservoirs under given conditions. The geological factors of their formation and accumulation are organic lithofacies zones in favour of forming the condensate oil and gas system, fitting temperature and pressure conditions and fime-space metch of trap, migration and resrvoir conditions for forming condensate gas reservoirs.更多还原
