Description
Technical field
The present invention relates to field use auxiliary material field more particularly to a kind of drilling fluid anti-collapse and anti-falling filtration agent and its lifes
Production method.
Background technique
Borehole well instability is always the principal element for influencing drilling well and going on smoothly in drilling process, especially in deep-well, ultra-deep
Well, directional well and high angle hole it is increasing in the case where, the above problem seems more prominent, in the work progress of drilling well,
People are frequently added anti-sloughing agent and fluid loss additive to solve the above problems, and fluid loss additive is reduced to stabilizing mud properties
For harmful liquid to stratum leak-off and stabilizing borehole, the important mud conditioner for guaranteeing hole diameter rule, fluid loss additive is oil well water
Most important one kind in mud additive, usually required in cementing technology casing, production string and tail pipe be added fluid loss additive with
Control the liquid phase leak-off in cement slurry, it plays critically important effect to wellbore stability, protection oil-gas Layer, temperature resistance ability also compared with
It is low, usually only 150 DEG C~180 DEG C, and caving-preventing characteristic and drop filter effect also do not protrude, and with other drilling fluid compatibilities
It is poor, it is easy to pollute the environment.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of novel environment friendly high-temperature resisting and salt-resisting performances
