为有效地保护自然环境,成功研制出了抗高温(215℃)高密度(2.1 g/cm3)低毒油包水钻井液,并对该钻井液的原材料选择、室内配方试验及配方毒性等方面进行了研究。结果表明,低毒油包水钻井液满足了钻井施工的要求,其毒性满足了环境保护的要求。
In order to effectively protect the natural environment, a high-density (2.1 g / cm3) low-toxicity oil-in-water drilling fluid with a high temperature resistance (215 ° C.) has been successfully developed. The raw material selection, laboratory formulation test and formulation toxicity of the drilling fluid Were studied. The results show that the low poisonous oil-in-water drilling fluid meets the requirements of drilling construction and its toxicity meets the requirements of environmental protection.
