secondary generator

The gas generation of low mature source rocks has been simulated in the open system and close system respectively . the models of primary cracking gas ( gas from kerogen ) and secondary cracking gas ( gas from oil ) have been established . the ro value of primary cracking gas generation peak is ranged from 1 . 0 % to 1 . 5 % . the ro value of secondary gas generation peak is ranged from 1 . 5 % to 2 . 5 % 對低成熟(部分為成熟)的烴源巖在開放和密閉體系下的生氣熱模擬實驗研究建立了熱解氣和油裂解氣的生氣模式,熱解氣的生氣高峰在ro = 1 . 0 ? 1 . 5 ,油裂解氣生氣高峰是在ro = 1 . 5 ? 2 . 5之間,從熱解氣和油裂解氣的相對含量來看熱解氣占總生氣量的21 ,油裂解氣可能占79 ,油裂解氣產率為620m ~ 3噸

Under the upper pressures belt or minute super pressures of the upper triassic series and jurassic system interface formation , the fluid in the upper triassic series moved along stratum interface , fault and crack network thoroughfare , formed “ secondary gas pool “ in the jurassic system 上三疊統和侏羅系界面形成的超壓帶或微超壓帶,使上三疊統氣藏流體在壓力差的作用下,沿斷層、地層界面和裂縫網絡通道運移,在良好的侏羅系圈閉中形成“次生氣藏” 。

In this paper , according to the properties of secondary gas pools and the inclusion data , the secondary gas pools are though to be formed due to the leakage of the original gas pools penetratin through the regional caprock when the overpressures within lower overpressured strata release 結合包里體測試計算,認為期形成原因主要是由于下部超壓地層進行超壓釋放,從而在區域性盈層內部形成一系列泄壓道,原生氣藏泄漏而形成的。

The forming process of gas reservoirs includes three stages , that is , the formation of the primary gas pools with high temperature and high pressure , the leakage of the primary gas pools and the formation of the secondary gas pools , and late adjustment and maintenance of the secondary pools 形成過程主要經歷了下部高溫高壓原生氣藏的形成、原生氣藏泄壓與次生氣藏的形成、次生氣藏的長時間調整3個階段。
