| titleOfInvention | A kind of multi-functional composite fracturing liquid system |
| abstract | The present invention provides a kind of multi-functional composite fracturing liquid systems, including drop blocks water and highly viscous sand-laden fluid；It is calculated in mass percent, the drop blocks water including 0.02%~0.15% friction reducer；It is calculated in mass percent, the highly viscous sand-laden fluid includes 0.2%~0.75% thickener；The friction reducer is identical association polymer with thickener, is natural modified association polymer and/or organic synthesis association polymer.The present invention forms a kind of multi-functional composite fracturing liquid system with preferable resistance reducing performance and high concentration association polymer using low concentration association polymer with preferable solid-carrying performance, compared with existing composite fracturing liquid system,, formula few with additive types is simply, the feature of preparing process simplicity, while system has better drag reduction, shear resistant and takes grittiness；System is returned drain and can be reused after the processing such as flocculation, precipitation and filtering, and water blanket utilization rate is improved. |
