摘　　要：川东北地区整装高含硫气田的成藏规律是:在碳酸盐岩台地的边缘滩发育优质生物礁、白云岩孔隙储层;形成了带状常压大型古油藏;顶部巨厚的区域膏盐岩盖层,阻止藏内油气散失,油气高度集中富集;多烃经过高温裂解和硫酸盐还原作用,形成高含硫常压整装天然气藏;寻找台地边缘滩储层古隆洼格局是发现大型整装天然气藏的关键。The law of the large-scale high-sulfur gas fields ready to accumulation in northeastern Sichuan Basin: In the edge of the beach carbonate platform,Formed high-quality porosity reefs、dolomite reservoir;Formed a band of large normal pressure ancient reservoir;Thick of the regional cap gypsum rock and salt rock at the top,prevent the oil and gas in reservoir to loss,high concentration of oil and gas accumulation;Formed a high-sulfur normal pressure natural gas fields after high-temperature split and sulfate reduction of heavy hydrocarbon;Find pale uplift reservoir is the key to find a large natural gas deposits.
