摘要
钻井工程存在大量不确定性,具有高投入、高风险的特点。若能提前预测潜在的风险,根据现场实际情况采取相应措施,则可将风险发生的可能性控制在最低程度。钻井风险主要包括井漏风险、井塌风险、井涌风险、卡钻风险。这几类风险给钻井工程带来了巨大的困难。钻井地质环境(岩石力学参数、地应力状态、三压力剖面)作为引起四类钻井风险的主要影响因素,是钻井风险预测与诊断的基础。
There are many uncertainties in drilling engineering which has the characteristics of high investment and high risk.If you can predict the potential risks in advance and take corresponding measures according to the actual situation,the risk can be controlled to minimum.Drilling risks mainly include the risks of lost circulation,borehole collapse,kick and sticking,which bring great difficulty for drilling engineering.Drilling geological environment(rock mechanics parameter,the in-situ stress state,three pressure profile)as the main factor causing four types of drilling risks,is the foundation of drilling risk prediction and diagnosis.
