为获得最好的经济效益,对出砂的高粘原油采用防砂和携砂生产相结合的生产工艺。携砂生产不是主张出砂,它应用的前提是必须保持地层中骨架砂拱的稳定性,这一点和防砂是一致的;不同的是,携砂生产通过实施有效的人工出砂管理,允许少量易堵地层的砂子随产液流出,疏通地层孔隙,增大渗流面积,从而收到比防砂更好的效果。 In order to obtain the best economic benefits, the production process of combining high-viscous crude oil with sand control and sand-carrying production is adopted. Sand production is not advocated sand production, its application is based on the premise that we must maintain the stability of the framework of the sand arch in the stratum, which is consistent with the sand; the difference is that sand production by implementing effective manual sand management, allowing a small amount Easy to block the formation of the sand outflow with the production fluid to clear the formation pores, increasing the seepage area, which received better than sand control effect.
