对东营凹陷胜坨和牛庄油田油气包裹体进行了分析 ,结合其构造发育史、沉积埋藏史、热史和生烃史等的综合研究 ,探讨了东营凹陷油气成藏充注过程中油气运移的相态、运移通道及其成藏过程的脉动性和成藏的时间。首次在东营凹陷发现的沸腾包裹体说明了胜坨油田呈现“突发式”成藏的可能性和牛庄油田砂岩体油气充注“间歇性”的模式。研究结果表明 ,胜坨油田坨 76砂体油气充注的时间是东营末期至馆陶期 ,牛庄油田牛 2 1井区的油气充注时间是东营末期至现今
The hydrocarbon inclusions in the Shengdu and Niuzhuang oilfields of Dongying depression are analyzed. Combined with the comprehensive study of their tectonic development history, buried-burial history, thermal history and hydrocarbon generation history, the hydrocarbon migration in the Dongying Depression during hydrocarbon accumulation State, migration channel and its accumulation process of the pulse and accumulation of time. The first discovery of boiling inclusions in the Dongying depression shows the possibility of “sudden” accumulation in the Shengtuo oilfield and the “intermittent” pattern of oil and gas filling in the sandstone bodies of Niuzhuang Oilfield. The results show that the charge of Tuod76 sand body in Shengtuo Oilfield is from Dongying to Guantao period, and the filling time of Niu-21 well in Niuzhuang Oilfield is from Dongying to present
