Bentonite Rheological Additive In Drilling Mud
A, oil based mud rheological additive and filtration solutions with good performance, strong anti-pollution ability, viscosity coefficient of filter materials. Oil based mud can effectively drilling in complex stratum, in case of expansive mud stones, hale rock, salt rock, gypsum, which can prevent the collapse of the drilling; as it can also prevent mud expansion, it could protect the permerability of oil and gas reservoirs, it is suitable for low or high pressure oil and gas reservoir. The stability in high temperature is very strong, it is suitable for drilling in super deep well, oil based mud has super anti-corrision ability for metal against water, which can make the life a bit longer, and it can be used as drilling fluid for coring
Oil based mud is mainly used for solving the differential pressure sticking occurred in the process of drilling accidents,
B, Bentonite Rheological Additive
In emulsified oil based drilling mud, inverse emulsion oil based drilling mud, oil based drilling mud and oil based mud
formulation solution, when the solvent is diesel based, select CP-992 and CP-180 organic bentonite, when the solvent is mineral oil
the best choice is CP-150 organic bentonite, it can make the mud suspended, articles layer well, wall and anti-filtration
effect,when the medium pressure and temperature at 10 PA and 230C, it could still maintain the stability of chemical and
physical
