Abstract: A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) and proppant-spacing filler material (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the material (24), and removing the filler material (24) to form open channels (26) around the pillars (28). The filler material can be dissolvable particles, initially acting as a consolidator during placement of the proppant in the fracture, and later dissolving to leave flow channels between the proppant pillars. The well treatment fluid can include extrametrical materials to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.

Abstract: A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) wherein the proppant comprises from 1 to 100 percent in weight of stiff, low-elasticity and low-deformability elongated particles (34) and proppant-spacing filler material called a channelant (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the channelant (24), and removing the channelant filler material (24) to form open channels (26) around the pillars (28) for fluid flow from the formation (14) through the fracture (20) toward the wellbore (10). The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture. The channelant can be dissolvable particles, initially acting as a filler material during placement of the proppant in the fracture, and later dissolving to leave the flow channels between the proppant pillars. The well treatment fluid can include fibers to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.

Abstract translation: 公开了一种在地下裂缝中布置非均相支撑剂的方法。 该方法包括注入包括支撑剂（16）在内的井处理流体，其中支撑剂包含1至100重量％的刚性，低弹性和低变形性细长颗粒（34）和称为通道（18）的支撑剂间隔填料， 通过井眼（10）进入裂缝（20），将支撑剂不均匀地放置在由通道（24）间隔开的多个支撑剂团簇或岛（22）中的断裂中，并将通道填料（24）移除到 在所述柱（28）周围形成用于从所述地层（14）穿过所述断裂（20）流向所述井筒（10）的开放通道（26）。 支撑剂和输送管可以在井内处理液中分离，或在放置在裂缝中时分离。 通道剂可以是可溶解的颗粒，最初在将支撑剂置于断裂中时充当填料，然后溶解以留下支撑剂柱之间的流动通道。 井处理流体可以包括纤维以提供支撑剂的增强和固结，并且还可以或另外地抑制支撑剂在处理流体中的沉降。
