Nanometer Plugging Agent


The molecular chain of Nanometer Plugging Agent NP-1 carries various adsorption groups, which can firmly adsorb on the surface of shale. Its particle size is easy to seal the pores and layers of shale formation, prevent water and drilling fluid from penetrating and hydration the formation and thus stabilize the wellbore.

Technical Specification

Items Specifications
Appearance White Milk
API Filtrate Volume,mL ≤15.0
Particle Size D50 after 150℃/16h aging, μm ≤0.9
Penetration Index,mm ≤0.5


1.Median particle size D50 of nano sealing agent NP-1 is below 0.9μm, the size matching degree with shale bedding and micro cracks is high, which can play an effective sealing role;

2.NP-1 is composed of nanoscale dispersed polymer solid particles with a wider range of usage temperatures. Experiments have shown that NP-1 still has a good physical sealing effect at a wellbore temperature of 200 ℃;

3.NP-1 belongs to the non fluorescent sealing material and can be used for exploratory well construction, which can effectively improve the stability of the wellbore during exploratory well construction;
