The temperature resistance of the product reaches 200 \u2103, which will not cause viscosity increase in water-based drilling fluid and can assist in the formation of mud cake.<\/p>\n\n\n\n<p><strong>4. Usage<\/strong><\/p>\n\n\n\n<p>The general dosage is 3-4%, which has strong compatibility with other drilling fluid materials.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>1.
