Drag reducer in slick water fracturing fluid

The drag reducer products of our company are mainly applied in the construction of slick water fracturing fluid. As the main agent of the slick water system, the function of the drag reducer for fracturing is to reduce the friction coefficient when the fracturing fluid flows, thus reducing the construction pressure. Besides its low friction, it also features online blending, excellent solubility, low surface tension and simple construction. 

In terms of product performance, it can be classified into: conventional drag reducer, salt-resistant thickeners and acidizing thickeners.

It has high drag reducing performance, can be blended online, has good solubility, causes little formation damage, contains no insoluble substances, and is easy to flow back.

It features high temperature resistance, salt resistance, shear resistance, rapid solubility, low damage, excellent drag reducing performance, and simple treatment of flow-back fluid.

Green clean slic kwater integrates multiple key functions such as rapid dissolution, drag reduction, sand carrying, fluid discharging assistance, swelling prevention, and cleaning. 

--Green clean slickwater fracturing fluid is synthesized from biological substances, being non - toxic, harmless, safe, and environmentally friendly. 

-- Green clean slic kwater fracturing fluid can reduce formation adsorption and cause little damage to reservoir permeability. 

-- Green clean slic kwater fracturing fluid has a strong sweep ability, which can significantly increase the fracturing swept volume and achieve obvious production increasing effects. The on-site construction process of green clean slickwater is simple and convenient to use. Meanwhile, it has obvious cost reducing advantages. 

-- Green clean slick water fracturing fluid can meet the requirements of 100% flow-back fluid for liquid preparation.

The combined use of thickeners and drag reducer in the slick water fracturing fluid system is an effective way to resolve the contradiction between "viscosity" and "resistance", and has become a key technology for the development of unconventional oil and gas reservoirs. By rationally selecting the types of thickeners and drag reducer, and optimizing the compounding ratio and process conditions, a fracturing fluid system with both high-viscosity sand carrying capacity and low-resistance transportation performance can be obtained. 

Through the analysis of the action mechanisms of thickeners and drag reducer, the compounding principles, formula optimization methods, performance evaluation methods, and field application cases, the performance of the compounded system mainly depends on the molecular structures, interactions, and environmental adaptability of thickeners and drag reducer. Through molecular design, formula optimization, and process innovation, remarkable progress has been made in the compounded system in terms of temperature and salt resistance, drag reduction and sand - carrying, gel - breaking with low damage, etc.
