摘要
针对水包油钻井液的特点,从处理剂评价入手,通过室内试验优选出了乳化剂和增粘剂,在此基础上研制了一种水包油钻井液体系配方,并对体系的抗温性和抗污染能力进行了评价。试验结果表明:该水包油钻井液抗温能力达到160℃,具有较好的流变性、较强的稳定性、较低的虑失量和较好的抗污染能力,能够满足钻井施工的要求。
According to the characteristics of oil-in-water drilling fluid, starting from the evaluation of treatment agent, the emulsifier and thickener are selected by laboratory experiment. On this basis, a kind of oil-in-water drilling fluid system formula is developed. The anti-temperature properties and anti-pollution capability are evaluated. The experimental results show that this kind of oil-in-water drilling fluid system can resist 160 ℃ and has better rheological property, stronger stability, lower filtration and better anti-pollution capability, which can meet the requirements of drilling operation.
