中文摘要:汶川地震科学钻探四号孔(WFSD-4)在二开钻进过程中，钻井液受到了较为严重的CO2污染，造成钻井液性能变坏，具体表现为粘切升高，流动性变差，影响了正常钻进。通过分析CO2污染钻井液的影响因素，并结合钻井液遭受CO2污染的机理和特点，在室内实验和现场应用的基础上，总结出了CO2污染的规律、性能特征及相应的处理措施：即在保证钻井液pH值的条件下，通过石灰除去钻井液中的酸根离子等。

Drilling Fluid CO2 Contamination in WFSD-4 of Wenchuan Scientific Drilling and the Treatment
Abstract:In the process of the fourth hole (WFSD-4) of Wenchuan earthquake scientific drilling project, the drilling fluid was contaminated by CO2 seriously and the drilling fluid performance was deteriorated with sticking & cutting increasing and poor liquidity, by which normal drilling was affected. Through the analysis on the influence factors of CO2 on drilling fluid and according to the mechanism and characteristics of drilling fluid contamination by CO2, the contamination rules, performance characteristics and corresponding treatment measures are summed up based on the laboratory experiments and field application cases: with pH value of drilling fluid keeping, acid radical ion etc. in drilling fluid can be removed by lime.
