据估计在加拿大艾伯塔东北的油砂矿床含油量,比世界上所有普通可开采的石油都多。该石油是以沥青形式挤压在岩层中的。沥青是一种非常粘稠的焦油状物质,在典型的储油层温度下,它实际上呈现为固体。本文叙述了这样一种方法,根据岩层的传输线激励,可利用频率范围只几千赫到好几兆赫的电磁波加热岩层的方法来开采沥青。这种加热降低了沥青的粘稠度,使其能够流动。然后用适当的气体或液体作驱赶物质,把它从油基体岩层中赶出来。已从按比例缩小的物理模型中得到了实验结果。
Oil sands deposits in northeastern Alberta, Canada, are estimated to contain more oil than any common oil that can be mined in the world. The oil is extruded in the formation as a bitumen. Asphaltene is a very viscous tarry substance that actually assumes a solid at typical reservoir temperatures. This paper describes a method that can be used to mine bitumen by means of electromagnetic stimulation of rock formations using electromagnetic waves in the frequency range of only a few kilohertz to several megahertz, depending on the transmission line excitation of the formation. This heating reduces the viscosity of the bitumen, allowing it to flow. Then use the appropriate gas or liquid as a driving substance, it is driven out of the oil matrix rock. The experimental results have been obtained from the scaled-down physical model.
