Nano polymer microsphere polyacrylamide for profile control and flooding

【Product description】

Nano scale polymer microspheres are used to prepare nano polymer microspheres by inverse microemulsion polymerization. The product is highly resistant to high temperature and high salt, and has the characteristics of "injection, plugging and moving." Nano polymer microsphere polyacrylamide for profile control and flooding enters the formation with the injected water. Through gradual expansion and deformation and accumulation in the deep water washing zone of the reservoir, it can effectively block the high permeability pore throat, change the liquid flow direction, expand the micro sweep volume of water drive, and achieve the effect of water drive oil increase.

【purpose】

Effectively reduce the water production of oil wells, improve the non-uniformity of water absorption of injection wells, improve the longitudinal sweep coefficient of injection wells, and effectively improve the recovery of heterogeneous reservoirs.

【Technical indicators】

【Usage and dosage】

The recommended dosage is 1000 ~ 2000ppm. The profile control pump is used to inject it into the formation along with the injected water, and the well is shut in for setting. The water control effect is closely related to the nature of crude oil and formation structure. Before use, test shall be carried out to determine the addition amount and use scheme.

【Packaging and storage】

1.25L plastic barrel packaging, net weight 25kg; Or packaging according to customer requirements.

2.Store in cool, dry and ventilated warehouse. The shelf life is 24 months.
