- Besides, there are large scale of tight sandstone gas-reservoirs occurred in sandstone formations which are interbedded or nearly the hydrocarbon source rock of deep buried Triassic and Jurassic. 另外,埋深较大的侏罗系及三叠系中与烃源岩互层或很近的砂岩中存在规模很大的致密砂岩气藏;
- The latter method is more appropriate for the location of more deeply buried deposits. 后一个方法更适用于确定深理的矿体。
- THE COMPLICATIONS FROM atomic fallout naturally raise the question of whether any nonnuclear alternative could destroy deeply buried bunkers. 核子落尘造成的复杂问题必然让人想到,是否有核弹以外的替代方案可以摧毁深埋地下的掩体。
- According to different reformation types of palaeogeothermal fields,the reformations can been classified into deep buried reformation,thermal event reformation and stress reformation. 根据古地温场的改造或改变作用方式的不同可划分为深埋改造型、热事件改造型和应力改造型。
