摘    要:摘 要] 我国未来深部大陆科学钻探深度为12000m ~ 13000m,井底温度将达到350℃以上,钻井液将面临超高温高压环境,钻井液技术将面临严峻考验。本文重点介绍了国内外典型深井及超深井钻探和高温地热井钻探钻井液使用情况,提出了抗高温钻井液的主要技术难点是高温高压及污染条件下钻井液流变性、滤失量、润滑性控制。耐温250℃以上钻井液处理剂及体系、耐高温钻井液试验仪器和地面循环降温系统是超高温钻井液技术研究方向。

关 键 词:超深井  钻探  高温钻井液

Abstract:In the future,the continental scientific drilling depth of China will reach 12000m ~ 13000m,and temperature of the well bottom will exceed 350 ℃.The drilling fluid will face a super-high-temperature high-pressure fluid environment,and the drilling technology will face a severe challenge.This paper focuses on presentation about the applications of drilling fluid to typical ultra-deep wells and high-temperature geothermal boreholes in China and elsewhere in the world.It is proposed that the main technical difficulty of the high temperature drilling fluid is the controlling of rheology,filtration and lubrication,and that research direction of drilling fluid technology is temperature drilling fluid agent and systems for the ultra-high temperature above 250 ℃ as well as the high-temperature drilling fluid testing equipment and ground cycle cooling system.
Keywords:ultra-deep well  drilling  high-temperature drilling fluid
