HVFR^® - 高粘滑溜水非常规压裂液技术

特征和优势

Friction Reducing Agent KHF027LV is a slurry of an anionic high molecular weight polyacrylamides. Conventional Friction Reducers (FR) lower the pumping friction when the fluid is pumped at a high rate. However, it will not give viscosity and viscoelasticity for the fluid and thus, the proppant suspension capability is low. Unlike the regular FR, the High Viscosity Friction Reducer (HVFR) not only reduces friction, but also provides viscosity to the fluid resulting in better proppant suspension. More than 70% of the friction reduction can be achieved within one minute when the friction reducer is introduced to the mix water. The table below summarizes the characteristics and benefits of HVFR systems.

特征

High viscosity friction reducer (KHF027LV), clay stabilizer (KHF002C), biocide (KHF003 and KHF003N), flowback additive (KHF007S) and breaker (KHF011, KHF012, KHF013, KHF014) are the key additives used in the HVFR systems.
The laboratory procedures, quality assurance program and guidelines for field mixing and handling of HVFR systems are described in HVFR fluid manual.

基本性能及使用条件

HVFR technology was commercialized in 2017 successfully and has been applied in various unconventional oil or gas fields in the world. It has been proved to be effective in treatment of shale or tight sand reservoirs with the following conditions:

Temperature:	BHST 70-350F (21-177C)
Formation:	Various shale gas or shale oil formations
Mix-water:	Fresh water, brines, or seawater

Further information about field applications is described in documented “Case History of HVFR Technology”.

Typical rheological properties of HVFR fluids are shown in the following Figures.
