摘　　要：莺-琼盆地是一个高温高压盆地,钻探过程中一直面临异常压力界面识别难度大、压力窗口窄等作业风险。为了确保高温高压井的钻探成功,引入法国地质服务公司地层压力评价技术PreVue,对高温高压井进行随钻地层压力监测。该技术基于dc指数法结合伊顿公式进行实时监测,同时利用随钻工程参数和井况信息对地层压力综合评价。现场应用表明,该技术能够准确地监测地层压力变化,具有较好的实用性和实效性。The Ying-Qiong Basin is high-temperature and high-pressure,where the drilling is faced with the risk of abnormal pressure interface recognition and the narrow pressure window.In order to ensure the drilling success of high temperature and pressure well,the PreVue technology is introduced by France GeoServices to evaluate formation pressure.The technique is mainly used to monitor the formation pressure with the dc index method and the Eaton formula,and comprehensively evaluate drilling parameters and well information.The field application shows that the technology can accurately monitor the formation pressure changes,and has good practicability and effectiveness.
