Abstract: A technique facilitates a fracturing operation by maintaining the heterogeneity of proppant fluid as it is injected into reservoir fractures. The technique comprises using a blender to deliver proppant material in a pulsating manner to create pulses of proppant. The pulses of proppant are mixed with a fluid to create a proppant slurry having the pulses of proppant material separated by a second fluid. The proppant slurry is then split between a plurality of pumps which are operated to pump the slurry to a well. To maintain heterogeneity, the pump rates of the pumps are individually adjusted to control dispersion of the pulses of proppant downstream of the pumps and to substantially maintain the separated pulses of proppant material in the slurry. A wide variety of other system adjustments also may be made for enhancing the ability of the overall fracturing system to maintain separated pulses of concentrated proppant material.

Abstract translation: 一种技术通过在支撑剂流体注入到储层裂缝中时保持支撑剂流体的异质性有利于压裂作业。 该技术包括使用搅拌器以脉动方式递送支撑剂材料以产生支撑剂的脉冲。 支撑剂的脉冲与流体混合以产生具有由第二流体分离的支撑剂材料的脉冲的支撑剂浆料。 然后将支撑剂浆料分离在多个泵之间，这些泵被操作以将浆料泵送到井中。 为了保持异质性，泵的泵速率被单独调节以控制泵下游的支撑剂的脉冲的分散，并且基本上保持浆料中支撑剂材料的分离的脉冲。 还可以进行各种各样的其他系统调整，以增强整个压裂系统维持浓缩的支撑剂材料的分离脉冲的能力。
