抗高温高性能水基钻井液及其在深层油气开发中的应用研究

High temperature resistant and high-performance water-based drilling fluid and its application research in deep oil and gas development

深层油气高效开发是中国对能源战略的迫切要求,也是我国进行深度勘探的主要内容,而石油钻井与开采则是其有效开采的核心。随着深层油气开采逐步向耐高温、高压的方向发展,钻井液系统在极端温度压力环境下保持其工作稳定是一个难题。钻井作业是石油天然气钻探项目的核心内容,也是钻探工程建设中的一个关键环节,研制高效的钻井液系统已成为当前钻探行业的研究热点。“安全、快速、优质、环保、高效”是当前石油天然气开采领域面临的重大挑战,这必然对钻井液、完井液提出更全面更高的技术要求。

The efficient development of deep oil and gas is an urgent requirement for China’s energy strategy,and it is also the main content of China’s deep exploration,with oil drilling and extraction being the core of its effective extraction.With the gradual development of deep oil and gas extraction towards high-temperature and high-pressure resistance,maintaining the stability of drilling fluid systems in extreme temperature and pressure environments is a challenge.Drilling operations are the core content of oil and gas drilling projects and a key link in drilling engineering construction.Developing efficient drilling fluid systems has become a research hotspot in the current drilling industry.Safety,speed,quality,environmental protection and efficiency are major challenges facing the current oil and gas extraction field,which inevitably pose more comprehensive and higher technical requirements for drilling and completion fluids.
