高含硫天然气勘探开发潜在危害分析与防范

Potential Hazard Analyses and Prevention of High-sulfur Natural Gas Exploration and Development

川东北地区大型天然气矿藏中硫化氢含量较高,且带有高剧毒性和高腐蚀性,勘探开发难度较大。同时气田所处区域的岩土条件十分脆弱,洪涝、大风、冰雹等气候灾害经常发生,易引发泥石流、滑坡,形成地质灾害。另外气田所在地人口密度大,给勘探开发设施布局和居民安全带来很大困难。文章通过对川东北地区天然气勘探、开发过程中存在的潜在危害进行详细分析,提出风险防范技术与对策,以供参考。

With high hydrogen sulfide content,the large natural gas reserves in northeast Sichuan are highly toxic and corrosive which pose a difficulty to the exploration and development.Meanwhile geotechnical conditions of the gasfield are very fragile and floods,strong wind,hail and other climatic disasters occur frequently which easily trigger mudslides,landslides and other geological disasters.In addition,the population of the gasfield is large which brings great difficulties to exploration and development facility layout and safety of the residents.This article analyzes potential hazards of the area in the process of natural gas exploration and development and proposes techniques and countermeasures of risk prevention for reference.
