摘要
用实验模拟莺歌海盆地中中新统梅山组在高温高压封闭含水环境下产生地压气和烃类水相运移机制,其结果直观地显示了地压气形成和运移过程中烃类的化学组成变化。预测若开采莺歌海盆地地压气,天然气将伴生产出高比重的凝析油,以及地压气随地层水向上倾方向运移时形成常规天然气藏的油气特征,进而验证了崖13-1气田的油气来自莺歌海盆地,并由水相运移而聚集。
An experiment has been conducted to simulate and study generation of geopressured gas and mechanism of hydrocarbon migration in water phase in a high temperature,high pressure closed and water-bearing setting.as such a setting is believed to exist in Meishan formation of the middle Miocene of Yinggehai basin.Results of the experiment show apparently how the gas is generated and what chemical changes of hydrocarbons take place during process of migration.In addition the experiment suggests the gas if produced would be associated would be associated wigh high API condensate.Moreover,it also forecasts characteristics of the conventional gas pool which is formed with updip migrates of the gas in formation water.lastly this experimental confirms that YA1 3-1 gas field is sourced by Yinggehai basin and formed via water phase migration.
