摘　　要：通过对深水钻井过程中钻井液面临的挑战和现有钻井液流变仪的分析,指出目前钻井液流变性测试仪器对评价深水性能存在的不足,重点介绍了用于评价深水条件下钻井液流变特性的新仪器——FannIX77全自动钻井液流变仪,详细阐述了该仪器的结构原理、组成、特点、技术指标及操作模式等。该仪器模拟温度范围在-10℃~316℃之间、最高压力可达30000psi,不仅适用于高温高压井的评价测定,尤其对深水作业时钻井液性能的评价更显示其独有的优势。文章以比重为1.2SG的水基钻井液和合成基钻井液体系为研究对象,介绍了该流变仪在深水钻井液流变实验中的应用。The Challenge of drilling fluids in deepwater drilling and the shortage of present rheometer for evaluation of mud′s rheology in deepwater are analyzed.A new fully automatic rheometer,FannIX77 is introduced in evaluating deepwater drilling fluids,and it′s structure,characteristic,technical description and operational models are introduced in detail.This stimulating temperature rang of FannIX77 is from-10℃ to 316℃,and the max pressure is up to 30000 Psi.The instrument is not only suitable for HTHP evaluation,but also has unique advantage in deepwater drilling fluids evaluation.In this paper,we research the rheology of four water-based drilling fluids and synthetic-based drilling fluids under low temperature and high pressure,and discussed it′s application in deepwater drilling fluids.
