Friction reduction fluids

摘要

The invention provides an oilfield suspending friction reducer treatment composition fluid comprising from about 0.001 weight percent to about 0.5 weight percent of a drag reducing surfactant; at least one drag reducing enhancer selected from the group consisting of polymeric drag reduction enhancers, monomeric drag reduction enhancers, and mixtures thereof.

1. An oilfield fracturing treatment method for reducing friction comprising the steps of:
providing a suspending friction reducer fluid comprising:
from about 0.001 weight percent to about 0.5 weight percent of a drag reducing surfactant comprising at least one surfactant selected from the group consisting of cationic surfactants, protonated amine surfactants, zwitterionic surfactants, anionic surfactants, amphoteric surfactants and mixtures thereof,at least one drag reducing enhancer selected from the group consisting of polymeric drag reduction enhancer, monomeric drag reduction enhancers, and mixtures thereof, and injecting said suspending friction reducer fluid into a wellbore as a hydraulic fracturing treatment fluid, initiating and propagating a fracture in the formation during a PAD stage of the hydraulic fracturing treatment, and allowing said fluid to enter a subterranean formation penetrated by the wellbore, and achieve a percent drag reduction of at least 20%, wherein the total amount of the drag reduction enhancer is no more than about 0.2 weight percent.
