The charged molar ratio of heterocyclic compound is 1:2.5；Aminated compounds and base metal catalysts mass ratio are 1200:1.
Comprise the concrete steps that:
(1) add aminated compounds in reactor, gradually heat up；Aminated compounds rheological characteristic strengthens；
(2) base metal catalysts deionized water is made into the aqueous solution that concentration is 10%, is uniformly added in reactor, with amine
Compound is uniformly mixed；
(3) constant temperature after being heated up to 85 DEG C, is uniformly added into heterocyclic compound, controls temperature of reaction kettle and is less than 100 DEG C, mix homogeneously
Rear holding constant temperature continues reaction 2h, treats that material is become fully transparent from muddiness, show that polyreaction completes that cooling discharge obtains
Shale polyamine class inhibitor.
Described alkali metal compound refers to potassium hydroxide or sodium hydroxide.
Compared with prior art, what the present invention was reached has the beneficial effect that:
(1) this inhibitor has high inhibition ability to mud shale, good with other conventional drilling liquid inorganic agent compatibilities, and without poison ring
Protect.
(2) this inhibitor has substantially no effect on the rheological characteristic of drilling fluid after adding drilling fluid, can improve drilling fluid simultaneously
Shut-off capacity and lubricating ability, reduce the filter loss of drilling fluid.
(3) this inhibitor is by introducing new functional group, can significantly improve drilling fluid system temperature resistance ability.
(4) raw material of synthetic drilling fluid shale polyamine class inhibitor is generalization chemical product, originates quite varied, closes
Become that technique is simple, safe and environment-friendly, easily operate, it is simple to commercial production.
(5) after this drilling fluid shale polyamine class inhibitor being joined in drilling fluid, under the conditions of identical dosage, than other
With type inhibitor, there is higher rejection ability.
(6) drilling fluid shale polyamine class inhibitor is while significantly improving drilling fluid rejection ability and temperature resistance ability,
