海底天然气渗漏形成水合物量的线性动力学模型:以墨西哥湾GC185区块Bush高地为例

世界许多地区如墨西哥湾，存在着大量天然气渗漏并形成水合物的现象，出于科学，生态，气候和安全的需要。人类有必要弄清存在于海底以水合成形式存在的天然气的比例。因此，构建了水合物形成量的线性动力学模型，以分析墨西哥湾GC185块区Bush高地海底渗漏天然气的地质过程和行为。Bush高地渗漏的天然气来源于附近的Jolliet气藏，结果表明，渗漏天然气中约有9％的海底形成了水合物。

A kinetic model of hydrate formation to calculate the fraction of venting gas precipitated beneath seafloor: An example of the Bush Hill vent site, GC185, Gulf of Mexico

Gas vent and hydrate formation occur at innumerable sites in the Gulf of Mexico and other places around the world. For scientific, ecological, climatological, and safe reasons, it is important to obtain the mass fraction of these gases precipitate as hydrate in the subsurface. Therefore, a linear kinetic model of hydrate precipitation is constructed to trace geological process and formation of venting gas from Jolliet reservoir in Bush Hill, GC 185, Gulf of Mexico. The Bush Hill vent is fed by gases reservoirs in the nearby Jolliet field. The estimation depending on this linear kinetic model shows that on an average about 9%of the venting gas is formed as hydrate under the Bush Hill seafloor.
