【摘要】：可逆乳化钻井液可集中水基钻井液与油基钻井液的优势。现有可逆乳化钻井液所用乳化剂为表面活性剂,考虑用改性纳米颗粒制备可逆乳化钻井液提高其耐温性能和稳定性。本文优选可制备可逆乳状液的改性纳米颗粒,在此基础上制备可逆乳化钻井液,并进行性能评价。经研究,改性纳米颗粒3可制备可逆乳状液,在此基础上制备可逆乳化钻井液,与表面活性剂HRW稳定的可逆乳化钻井液(乳化剂用量1.4%)相比,所制备可逆乳化钻井液在乳化剂用量较少(0.8%)的情况下,保持良好的可逆转相性能、滤饼清除和含油钻屑处理性能,且在耐温性能(180℃)和稳定性(1000VW/O乳状液破乳电压)方面明显优于表面活性剂HRW稳定的可逆乳化钻井液(耐温120℃,550VW/O乳状液破乳电压650V)。
[Abstract]:Reversible emulsified drilling fluid can concentrate the advantages of water-based drilling fluid and oil-based drilling fluid. The emulsifier used in reversible emulsified drilling fluid is used as surfactant. The preparation of reversible emulsified drilling fluid with modified nanoparticles is considered to improve its temperature resistance and stability. In this paper, the modified nanoparticles of reversible emulsion can be prepared, on the basis of which, reversible emulsified drilling fluid is prepared and its performance is evaluated. The reversible emulsion can be prepared by modified nano-particle 3, and the reversible emulsified drilling fluid is prepared on this basis, which is compared with the reversible emulsified drilling fluid stabilized by surfactant HRW (1.4% emulsifier dosage). The reversible emulsified drilling fluid with less emulsifier dosage (0.8%) has good reversible phase properties, filter cake removal and oil drilling chip treatment. The reversible emulsified drilling fluid (120 鈩，
