Study result suggest: The change of stock in RFCCU directly affect gasoline content. Gasoline content can be reduced through increasing the equilibrium activity of catalyst, controlling reaction level, increasing recirculating rate of gasoline and stability of gasoline level. Conclusions drawn from experiment is that optimization of operating condition has great effect on lowering olefine content of gasoline which can be reduced from 60% to 50%.Reducing reaction temperature is useful for lowering olefine content of gasoline, when the reaction temperature is raised, thermal cracking rate is higher than catalytic cracking rate, so that olefine content is increased. Raising catalyst-to-oil ratio is good for lowering olefine content. With conversion rate increased, the yield of LPG and coke is raised, the yield of gasoline is increased firstly and then decreased slightly, hydrogen transfer index is increased, so the olefine content is decreased.

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。
