Highly efficient cleaning fracturing fluid is a new type of high viscosity synthetic polymer. This fracturing fluid has very good sand carrying capacity and resistance reduction, and is very stable after preparation. It can be used for various fracturing such as conventional fracturing and volume fracturing. It has good application prospects for conventional oil and gas reservoirs and shale gas reservoirs, and is suitable for oilfield regulation. Due to viscosity adjustment, emulsion slippery, strong sand blasting ability, low friction resistance and low sedimentation speed, it breaks through the limitations of foreign conventional slick water. It can carry sand efficiently, thus saving a lot of water and operating costs.
Technical advantages:
Online configuration: no need to configure in advance, as long as the site and clean water are added to the container in a certain proportion to stir, saving the liquid dispensing time and material cost.
It has strong sand-carrying ability, high liquid efficiency, good controllability and strong seam-forming ability. The sand ratio can reach 35-199%, which can be adjusted according to the site conditions. The friction is low, the pressure loss is reduced, the formation is smoothly opened, and the displacement is increased. Because it is super slippery, the bottom of the friction is 5-45%, the average is 1/3, 2000-3000s-1, 1% efficient cleaning fracturing fluid on-site determination of 60% of the water without residue, the drug selection takes five solid phases, almost No residue, can be diluted with water, completely soluble in water, no residue, no damage, can be completely reversed, no damage to the formation.
