[Abstract]:A high temperature resistant main emulsifier HT-MUL, for oil based drilling fluid was synthesized from tul oil fatty acid and maleic anhydride as main raw materials. The optimum acid value of tul oil fatty acid monomer and the optimum addition amount of maleic anhydride monomer to HT-MUL were determined. The results showed that the emulsifying ability of HT-MUL was good. When the oil / water ratio is 60:40, the maximum demulsifying voltage of the emulsion with oil / water ratio of 60:40 can be up to 490 V / 90: 10. The highest demulsification voltage of the emulsion can be as high as 1 000 V, which can be obtained from the resistance to temperature and filtration. The emulsification ratio of HT-MUL is compared with that of the domestic and foreign products. The results show that the emulsion prepared by HT-MUL has higher demulsification voltage, less filtrate loss, higher emulsification rate and better overall performance than the domestic and foreign similar products. A high density oil-base drilling fluid was prepared by using the main emulsifier HT-MUL. The performance evaluation shows that the basic properties of the system are good, and the demulsification voltage is up to 800V after hot rolling at 220 鈩，
