高石梯―磨溪构造带是四川盆地震旦系灯影组重要的勘探前景区。应用激光荧光、包裹体和同位素等技术判识了油气运聚信息,分析了灯影组圈闭演化及储层特征,建立了成藏模式。高石梯-磨溪构造带在加里东运动后形成了相对古隆起区,在印支、燕山和喜山早期仍为古隆起区,喜山晚期运动形成了大型圈闭。该区有溶洞型、孔洞型和裂缝型3类含气层,分为震旦系顶部和灯二段两套含气组合。该区烃源岩主生油气期为早中侏罗世,主生气期为早白垩世,是一个持续演化的背斜型气藏。因此,该区是油气运移指向区,是有利勘探区带。

Gaoshiti-Moxi structure belt is the important exploration area of Sinian Dengying formation. The laser fluorescence, inclusion enclave and isotope technologies etc are used to obtain the gas migration and gather information. Though the trap evolvement and reservoir characters are analyzed, and reservoiring model of is  made. The Gaoshiti-Moxi was a palaeohigh area  after Caledonian movement, through the Indosian, Yanshanian and early Himalayan movement the palaeohigh area was  keeping. The belt is big trap after later Himalayan movement. There are three gas-bearing formation types of cavern, pore space and fractural interval, it can be  divided into two gas-bearing units that are Sinian top unit and dengying 2 formation unit. Combining with hydrocarbon simulation study, the main phase of oil  generation for source rocks is early-middle Jurassic, the main phase of gas generation is early Cretaceous, The Gaoshiti Moxi is evolving anticline gas  reservoir. The Gaoshiti-Moxi structure belt is favorable to migrate and assemble oil and gas, so it benefit to exploration.
