摘要:
A method for extracting bitumen from a subterranean oil sand deposit including: drilling a portion of the deposit; fragmenting the drilled deposit; drilling of the fragmented deposit to allow for flooding, wherein one or more wells are drilled to provide access to the deposit and retrieval of extracted bitumen, to form a drilled fragmented deposit; flooding the drilled fragmented deposit with a first flood volume of fluid to permit the first flood volume of fluid to admix with the fragmented first portion, to release heavy oil from any inert material so that the heavy oil floats within the first flood volume of fluid in the drilled fragmented deposit to form a flooded first portion; recovering the heavy oil; and repeating the above for each additional portions.
摘要(中):
一种从地下油砂矿床中提取沥青的方法,包括:钻一部分矿床; 分割钻孔矿床; 钻探碎裂沉积物以允许淹没,其中钻出一个或多个井以提供对提取的沥青的沉积和取回的通道,以形成钻出的碎片沉积物; 用第一淹没流体体积淹没钻出的碎片沉积物,以允许第一淹没体积的流体与碎裂的第一部分混合,从任何惰性材料中释放重油,使得重油漂浮在第一淹没流体体积内 钻出的碎片沉积物形成淹没的第一部分; 回收重油; 并对每个附加部分重复上述操作。
