Zusammenfassung: | The invention discloses a method for exploiting underground water dissolved helium in the technical field of helium development. The method comprises the following steps that effective trap of helium-rich formation water and the flow direction of underground water are determined; injecting carrier gas into the lower part of the trap, so that helium is desolventized from water at a gas-water interface and enters the carrier gas; the carrier gas can naturally migrate to the top of the water trap to form a helium-rich reservoir; and drilling a well at the top of the trap, and exploiting a helium-rich reservoir.
本发明公开了氦气开发技术领域的一种开采地下水溶氦气的方法,包括以下步骤:确定富氦地层水的有效圈闭及地下水流向;向圈闭的低部位注入载体气,以使氦气在气水界面从水中脱溶进入载体气中;载体气会自然运移至水圈闭的顶部形成富氦气藏;在圈闭的顶部钻井,开采富氦气藏。 |
