| titleOfInvention | Tackifying and cutting-improving agent for oil-based drilling fluid and preparation method and application thereof |
| abstract | The invention discloses a tackifying and cutting-improving agent for oil-based drilling fluid and a preparation method and application thereof. The tackifying and cutting agent is prepared by reacting poly fatty acid and amino-terminated polyether under the conditions of heating and nitrogen protection atmosphere, wherein the poly fatty acid and the amino-terminated polyether are added according to the molar ratio of carboxyl to amino of 1:03-0.5, the reaction temperature is controlled at 160-200 ℃, and the tackifying and cutting agent is obtained by heating for 30min after heating until no water is generated. The tackifying and shear strength improving agent has good suspension performance in the oil-based drilling fluid, and the dynamic-plastic ratio and the shear strength of the system are obviously improved. |
