Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, has developed a kind of preparation method of high-temperature diluent of drilling liquid.
The preparation method of a kind of high-temperature diluent of drilling liquid of the present invention phenylethylene-maleic anhydride sodium salt 30~50kg, feero-chromo-lignosulfonate 50~75kg, water 250~300kg is formulated, and its concrete operation steps is:
A, in container, add entry 250~300kg, be heated to 45~55 ℃;
B, in the hot water of a, add phenylethylene-maleic anhydride sodium salt 30~50kg, stirred 10~40 minutes, fully dissolve;
C, slowly add feero-chromo-lignosulfonate 50~75kg in the solution of b, stirring and dissolving guaranteed not have caking in 10~40 minutes.
It is strong that a kind of high-temperature diluent of drilling liquid of the present invention preparation has a high temperature resistance, and dilution property is good, advantages such as cost is low, cleanliness without any pollution easy to use.
