The non-penetrating treatment agent is a micelle polymer containing small molecules, which can form micelles
on the rock surface of the shaft wall. Depending on the interface suction of the polymer micelle or the micelle
and its deformability, the non-penetrating treatment agent can block a large area of the rock surface Of the
pore and throat to form a dense and impermeable plugging film on the surface of the rock wall and effectively
block the different permeability strata and microcracked mud shale formation and form a protective layer on
the periphery of the wall and the drilling fluid and its filtrate are completely isolated Will penetrate into the
formation, can achieve close to zero loss drilling.
Drilling fluid properties
Physical and chemical standards
1, can be closed non-homogeneous permeability of formations, including micro-fractured shale formation;
2, to a certain extent, can improve the pressure of formation rupture;
3, can widen the drilling fluid density window;
4, can use the same drilling fluid into different pressure strata;
5, speed up drilling speed, improve drilling, completion quality;
6, can significantly reduce the complexity of the wells and reservoir damage.
