Reservoir protection effect.But, owing to the high molecular polymer in clay-free drilling fluid under the high temperature conditions is degradable, cause
The viscosity of drilling fluid, shear force are relatively low, carry suspension landwaste relatively difficult, can cause the adverse consequencess such as bit freezing.At salt-water drilling fluid
With in organic salt drilling fluid due to the salt shielding action to polymer molecule so that drilling fluid viscosity and shear force decline rapidly, with
Sample cannot carry and suspend landwaste, is then likely to result in down-hole complicated.In construction usually through increase viscosifier maintenance consumption or
Shorten maintenance period and cut performance so that guarantee drilling fluid is viscous, the most not only add cost but also other performances of drilling fluid may be constituted
Impact.
In recent years, at home, biogum class viscosifier are cut performance receive the favor of vast researcher with being carried of its excellence,
But affected by factors such as selling at exorbitant prices and heat resistance differences, limited its being widely used in drilling fluid.In addition
Also having cellulose family viscosifier and synthesized polymer species viscosifier, although cellulose family viscosifier cost is relatively low, but performance is the most relatively
Difference, in high temperature well, application is seldom, and domestic main synthesized polymer species viscosifier have acrylate polymer 80A51 and second
Alkenyl monomer multiple copolymer PAC141, both viscosifier products thickening efficiency slightly improves, temperature tolerance the most relatively biogum class
Height wanted by viscosifier and cellulose family viscosifier, but high temperature (> 130 DEG C) still can not meet performance during application under high content of salt and want
