高含硫气藏水合物形成机理的实验研究

EXPERIMENTAL INVESTIGATION OF HYDRATE FORMING MECHANISM IN GAS RESERVOIRS WITH HIGH SULFUR CONTENT

近年来随着川东北罗家寨、铁山坡等高含硫气藏的相继勘探成功 ,这些气藏将成为川渝地区重要的接替区块。对高含硫气藏水合物机理进行了实验研究 ,并对实验原理、实验方法、实验现象等进行了详细论述。首次得出了高含硫气藏水合物在实验条件下是按照天然气的比例以混合物整体形式同时与水分子结合形成的 。

Gas reservoirs with high sulfur content are found one by one in Luojiazhai, Tieshanpo, etc. of Northeast Sichuan area. Aiming to the hydrate forming mechanism of gas reservoirs with high sulfur content, the experimental investigation was conducted. The article discusses the experimental principles, methods, and phenomena in detail. It was demonstrated under the experimental conditions the hydrate formation of gas reservoirs with high sulfur content was according to the mechanism of the whole gas mixture combining with the water molecules but not the optimal principle one by one combining.
