摘要
针对麻黄山西部区块深部地层特点及难点,在室内优选抗高温钻井液体系,并对该体系进行性能优化研究,逐步改善其抗温、抗污染能力,并引入SPC-220与磺化处理剂发生高温交联,进一步增强体系的抗盐污染能力。宁深1井现场应用证明,该抗温钻井液体系性能稳定,对井下复杂情况的处理及顺利钻达目的层起到了关键作用。
According to the deep formation characteristics of west block of Mahuangshan, high temperature-resisting drilling fluid system was selected in lab and study was made on the performance optimization. The high temperature tolerance and anti-contamination abilities were improved, crosslinking reaction between SPC -220 and sulfonating agent was introduced for improve the ability of anti-salt pollution. The field application of Ningshen well 1 proved that the property of the high temperature-resisting drilling fluid system is stable and has played important role in the construction of complex formations.
