    • A method for recirculating fluid in a well system includes drilling a first well bore from a surface to a subterranean zone, and drilling an articulated well bore that is horizontally offset from the first well bore at the surface and that intersects the first well bore at a junction proximate the subterranean zone. The method also includes drilling a drainage bore from the junction into the subterranean zone, and receiving gas, water and particles produced from the subterranean zone at the junction via the drainage bore. The gas, water, and particles are received from the junction at the surface, and the water is separated from the gas and the particles. The method also includes determining an amount of water to circulate, and recirculating a portion of the separated water according to this determination.
    • 用于在井系统中再循环流体的方法包括从表面到地下区域钻探第一井眼,以及钻出铰接井眼,所述铰接井眼在表面处水平地偏离第一井眼,并且在第一井眼处与 接近地下区域。 该方法还包括从连接点钻入排水孔到地下区域,以及接收气体,水和通过排水孔从连接处的地下区域产生的颗粒。 气体,水和颗粒从表面的接合处接收,并且水与气体和颗粒分离。 该方法还包括根据该确定确定一定量的水循环并使一部分分离的水再循环。
