Detailed Product Description

The modified asphalt FT-342 takes high-softening-point asphalt as raw material. It turns into a kind of efficient shale inhibitor via special processing. It has several functions and characteristics as follows:
 1.As a kind of shale inhibitor, it can efficiently prevent the mud shale from hydrating, swelling and dispersing.
 2.After high temperature softening, its particles can seal off the microcrack of the formation and prevent the peeling-off collapse.
 3.Through taking part in the shaping of the sidewall mud cake, the particles of the asphalt can evidently cut down the lubrication coefficient of the mud cake and reduce the bit freezing.
 4.It can efficiently reduce the high temperature high pressure filtration.
 5.The characteristic of oil-soluble can perfectly protect the permeability of the oil-layer and increase the out-put of the crude oil.
