摘要： A method of improving injectivity of fluid, particularly produced water, in enhanced hydrocarbon recovery is disclosed. The method includes introducing a fracturing fluid into the subterranean formation to create a fracture, and introducing proppant into the fracturing fluid to form a single layer of proppant in the fracture. The fracturing fluid can be formed from produced water. Alternatively, the produced water is introduced after a fracturing fluid, other than the produced water, has been introduced to create a fracture. By reducing the amount of proppant and by using much larger proppant, a larger flow path through the fracture is created, thereby increasing the injectivity of produced water.

摘要： Herein is described a method of completing an interval of a cased well drilled through incompetent formation. This method includes a combination of three successive operations: zero-degree phasing perforation of a relatively small portion of the interval to be completed, consolidation of the formation zone around the perforations and injection of a propped fracturing fluid above fracture pressure to create a gap between the cement and the borehole and pack this gap with a proppant held by a proppant flowback-retention agent.
摘要翻译：这里描述了完成通过无能力地层钻探的套管井的间隔的方法。该方法包括三个连续的操作的组合：要完成的间隔的相对小部分的零度相位穿孔，穿孔周围的形成区域的固结以及在断裂压力之上的支撑压裂流体的注入，以在水泥和钻孔，并用支撑剂逆流保留剂保持的支撑剂填充该间隙。
